Many novice computer users, faced with files of an unknown format, including RTF, do not know how to open them.

What is an RTF file? Rich Text Format, translated from English as "rich text format" from Microsoft Corporation, supported by many versions of operating systems and text editors. These are text documents, for creation, as well as for opening, editing, changing, popular computer word processing applications are used. Using this format, text is typed, saved and copied for other operating systems. It is characterized by the content of only text data. However, they can be typed in any other format, but the final save is performed in the RTF extension. Transferring his text material from one program to another (Microsoft Office) is quite simple. The same applies to operating system versions.

Why RTF files are needed

They allow you to format the text, highlight its sections in italic or bold, underline some elements. Printed characters can be selected in different fonts and colors. With the RTF file format, it is easy to set a different spacing between lines, set the indent of text material relative to the edge of the sheets. It is in great demand among computer users.

Opening an RTF file using programs and services

This format has versatility, which is its undeniable advantage. You can open the program for RTF files using the Word application included in the MS Office package. It is the most successful product offered by this corporation and is used as a standard in word processing. It features an attractive interface with presented features. The Microsoft Office suite includes Project, Visio, InfoPath, Designer, PowerPoint, SharePoint, Excel, Access, Outlook. It is worth noting that Word is considered the best among text editors.
To open books in an RTF file, you can use the Kingsoft Writer application included in the Kingsoft Office suite. This is a free text editor. It is characterized by the same functions as the above Word program. The application can be installed both together with the entire package, but also as a standalone document. It has a classic interface similar to other text editors. It is used to create and format text material with the introduction of formulas, diagrams, graphs, images, three-dimensional symbols. Like Word, Kingsoft Writer is provided with a separate window for inserting a number of characters that are not on the keyboard. It allows you to instantly convert materials to a PDF file without resorting to the use of additional tools. The tabbed interface makes it possible to run multiple files in one window.
To open the RTF format, use the OpenOffice.org program, a multifunctional office application package with multilingual support. It is run by all major operating systems. The program allows you to store all data using its own open ODF format. It has been approved by the international organization for standardization ISO. One of the best features is the export of text to a PDF file with a single mouse click. Flash technology is supported here. The program interface is quite clear and convenient.

Note. A license is not required to install OpenOffice.org, which in turn allows each user who wishes to install it on their PC.

Notepad2 also supports RTF format. This is a small but fast enough text editor with syntax highlighting. Its interface is simple and attractive. The program does not require installation.
You can solve this problem with the help of AbiWord, a tool that processes text documents. It can print, edit, create various materials, as well as process letters and messages.

How to open RTF on a computer

The regular WordPad application located in the Start menu will help you open the file on your computer. Having launched it, you need to activate the main menu button with the mouse and select the "Open" item and specify the path to the document to be opened. The application displays the entire catalog of supported formats, RTF is not an exception.
Also, the context menu allows you to open the required file by right-clicking on the document icon. The menu that opens will display all the programs to view it.

The Smart Office program downloaded to a tablet or other mobile device will help you open RTF on Android.
The Cool Reader program supports this format quite well in this operating system. Good display of the table of contents, headings, images, which cannot be said about tables.

How to open RTF online

To open RTF online and make changes to them, you can use almost all text editors of popular operating systems (Mac OS, Windows) and many free office programs. Therefore, by sending documents in this format by e-mail, there is no doubt that it will be easy for the recipient to open and study them online, even if Office is not installed on his PC.
Opening a file online is easy in Google Docs. After going to their address, you need to click the "Open" tab. In the lower right corner, the "Create Document" box is activated. In the menu that opens, select "Open". In the "Download" tab, activate "Open" with the mouse and select the file of this extension on the PC.

How to create an RTF file yourself

To create an RTF file yourself, you do not need any special skills, you just need to download and install the free Microsoft Office Excel Viewer for Windows. Its interface is quite simple. For the Mac operating system, Apple TextEdit is suitable. This program is considered the main one for this OS. Having created a text document, select the desired format when saving.

Converter for RTF files

Converting documents from one format to another is possible with the converter for RTF files. Many services offer their services in this direction. Some do not even require special installation on the computer. The user needs to upload a file from a disk or other Internet resource to a special area for conversion. Next, confirm your actions. At the output, he will receive a high-quality document of the required format.

How to save a document as RTF: video

Many answers to the question of how to save an RTF document will be prompted by the video:

This format was defined by Microsoft as the standard format for exchanging text documents. Therefore, this format is similar in purpose to the SYLK format for spreadsheets. RTF is supported by many Microsoft products. For example, since version 2.0, it has been introduced into Windows as a Clipboard format, which makes it possible to exchange data between various Windows applications. In addition, the RT format is supported by WORD for Macintosh from version 3.X and WORD for PC from version 4.X.

RTF only uses character-representable codes from the ASCII, MAC, and PC character sets for document exchange. In addition to text, the file in RT format contains control commands in a readable form.

The document consists mainly of control commands for setting up a reader for files in RTF format. These commands can be divided into control words (control words) and control characters (control symbols).

The control word is a sequence of characters with a delimiter (delimiter) at the end:

\lettersequence

The control word is preceded by a backslash "\" (backslash). The following characters can be used as delimiters:

• Space (space), moreover, this symbol refers to the control word;
• Number or "-" sign. These characters must be followed by a delimited parameter. A space or other characters, except for numbers and letters, can be used as a separator;
• All characters other than numbers and letters. These symbols do not apply to control word.

The RT format uses the letters "A" through "Z" and "a" through "z" and the numbers "0" through "9" to specify the escape sequence. National characters do not apply to control information.

As, control characters separate letters are used. Each control character is preceded by a backslash "\":

\control symbol

Only a few of these symbols are currently defined. Therefore, unknown characters may be skipped when reading.

In the RT format, it is possible to combine individual sequences into groups using brackets:

(group start) group end

Such groups are created, for example, when describing footnotes, headers and footers, etc. If you want to place the characters "\", "(" or ")" inside plain text, then they must be preceded by a backslash:

\\ \{ \}.

This allows a program reading an RTF sequence to recognize that the character should not be interpreted as a control character.

The RT format also uses some character codes to control printing.

CR and LF characters within text will be skipped. Microsoft uses these characters for greater clarity when presenting an RTF file. Inside the control words, the characters CR and LF can have a special meaning, more about this will be discussed in the description of the commands.

Special control words

RTF has special-purpose control words. Let us briefly consider these words and their purpose.

Control word change page number displays the current page number.

Control word change footnote activates the automatic numbering of footnotes.

By using change date you can display the current date.

By using change time you can display the current time.

\chftnsep

Indicates a change in the line separating footnotes from text.

This sequence is used to enter the text of the formula.

Indicates a sub-item of an index.

Text may be skipped when reading RTF format.

Specifies a hard (non-breaking) space between two words, i.e. in this position, the sentence cannot be split when wrapping to the next line.

Symbol stands for soft hyphenation (nonrequired hyphen).

Symbol stands for unbreakable hyphen (non-breaking hyphen) where the word cannot be divided.

The sequence allows direct input of hexadecimal numbers in the text. They are given instead of the characters hh.

This sequence sets the transition to a new page.

This sequence causes a line break in the text.

With the help of this sequence, the end of a paragraph is marked in the text. Subsequence \par can be replaced by the sequence \ 10 or \ 13. Wherein \10 matches ASCII character code 10 (carriage return). ASCII code 10 (CR) cannot be entered directly because it is ignored by the reader.

This sequence marks the end of a text fragment or text paragraph.

This sequence replaces the tab stop. You can also directly set the ASCII code 09H.

End of table (column).

End of table (row).

Destination control words

The control words described below can be used to perform basic configuration of the RTF reader. They can only occur at the beginning of a document or at the beginning of a group. All operators along with parameters must be enclosed in parentheses, for example:

(\rtf0\pc.......)

The format of some operators is described below.

\rtf<параметр>

Specifies the start of the file. As a parameter, the program that creates the file can specify the version number. For example:

(\rtf0.......)

The label must be at the beginning of the file. This statement may be followed by other statements or a closing parenthesis.

Setting the type of encoding for the saved text is carried out using the following operators:

• \ansi: text is stored in standard ASCII format. This format is used, for example, in Windows.
• \mac:. text is stored in Macintosh encoding
• \rs: the text output uses the IBM-PC character encoding.
• \rsa: IBM-PC Code Page 850 (model PS\2).

To transfer texts between different systems, the \ansi encoding must be used.

\colortbl

Windows and other programs use palettes to determine which colors to use. Most often, the palette consists of 16 different colors, obtained by combining the primary colors - red, green and blue. Team \colortbl allows you to change individual definitions in the palette. For each color, the table indicates the value of the red, green and blue components. Each color is described by three parameters:

\red000 \green000 \blue000

Instead of 000, the value of the color fraction is specified in the range from 0 to 255. Example: in a table consisting of 16 colors, colors 0 and 2 must be redefined. To override colors, the following sequence can be given:

( \colortbl \red128\green64\blue128\;;\red0\green64\blue128; )

The color definition ends with a semicolon. Since the 1st color remains unchanged, there are two ";" characters in the sequence follow one after the other. The sequence ends with a closing bracket.

Operator \cfn defines the background color (with the default setting n=0), and the operator \cbn- symbol color (with standard setting n=0).

\fontbl

This operator is used to build a font table and correlates the name of a font (font group) with number font. When defining a font, you can use the following operators:

• \fnil: the name of the font group is unknown. The output should use a standard font.
• \froman: Roman fonts must be used (e.g. Times Roman)
• \fswiss: this operator specifies the use of fonts from the Swiss group (Helvetica, Swiss, etc.)
• \fmodern: Pica, Elite and Courier fonts can be used.
• \fscript: italic fonts of the Script group are used.
• \fdecor: when specifying this operator, fonts must be selected from the Decor group (Old English, etc.).
• \ftech: selection of a group of fonts with technical and mathematical symbols (SYMBOL, etc.).

The command to create a font group can consist of the following statements:

(\fonttbl\f0\fnil default;) (\fl\froman roman h;) (\f2\fswiss helvetica;)

After keyword \fontbl followed by the first font number \f0. Next comes the definition of the font group. Here, after the number 0 is indicated \fnil, those. group name unknown. The next parameter specifies the name of the font to select (for example, roman h). indication default tells the reader to use the standard font. The font name is followed by a semicolon. In the example above, only fonts numbered 1 and 2 are defined. The entire sequence can be grouped with curly braces.

The font table must be filled with values ​​before the operator is encountered \stylesheet or text. The standard font is entered by the operator \defn.

\stylesheet

This operator defines the font of the paragraph, i.e. the size, style, and name of the typeface, as well as how the text of the paragraph is aligned. It uses two key parameters:

• \basedon000: instead of the characters 000, the number of the font type that is used as the current one is indicated.
• \snext000: assigns the number of the next type of font (style), which - will become current.

An operator might look like this, for example:

(\stylesheet\s0\f3\fs20\qj Normal;) (\sl\f3\fs30\b\qc Heading Level 3;)

Fonts are numbered from 0 to n ( \s0...). In the first line paragraph style 0 ( \s0) is assigned the name Normal. Text output is done in font 3 ( \f3), 10 points in size ( \fs20). Parameter \qj says that the inscription should be format aligned. The second line defines font style 1, which gets the name Heading Level 3. The font has a size of 15 points, bold ( \b = bold) and the inscription is centered on output ( \qc).

\pict

This operator is used when describing a drawing in bitmap format. The following parameters contain the description of the picture as hexadecimal values. Parameters can be selectively used to define the geometry of a drawing or its format:

• \pich000: operator specifies the height of the drawing in pixels. Instead of three zeros, a numeric value is substituted. If there is no operator, the drawing height is determined from the current drawing data. With the help of the parameter, you can set a certain height for the picture.
• \piw000: operator sets the width of the picture in pixels. Everything said about the previous operator is true.
• \picscaled: with this operator, the picture is scaled so that it exactly fills the area allotted for it.
• \wmetafile: the parameter specifies that the data is stored in the Windows metafile format. The n parameter specifies the metafile type (1 = MM-text).
• \macpict: parameter specifies that the data is stored in Macintosh Quick-Draw format.
• \bin000:. parameter specifies the number of bytes. Instead of three zeros, a hexadecimal number is written.
• \wbitmapn: the parameter specifies the format of the bitmap. The n parameter specifies the type (0 corresponds to a logical bitmap).
• \brdrs: defines a simple frame for the picture
• \brdrdb: defines a double border for the picture.
• \brdrth: defines a bold line for the picture frame.
• \brdrsh: defines a shaded frame for the picture
• \brdrdot: defines a dotted line for the drawing.
• \brdrhair: defines a thin line for the picture frame.
• \picwGoaln: sets the desired image width in twips
• \pichGoaln: sets the desired height of the picture in twips.
• \picscalexn: sets horizontal scaling (n can take values ​​from 1 to 100, default is -10).
• \picscaleyn: specifies vertical scaling (n can take values ​​from 1 to 100, default is 10).
• \piccroptn: describes the top margin of a picture in twips. If the parameter n is positive, the upper part of the picture is cut off. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
• \piccrorbn: describes the bottom margin of a figure in twips. For positive values ​​of the n parameter, the lower part of the picture is cut off. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
• \pissrporrn: describes the right margin of a picture in twips. With positive values ​​of the n parameter, the picture is cut off on the right. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
• \piccropln: describes the left margin of a figure in twips. If the parameter n is positive, the picture is cut off on the left. Negative values ​​of n make it possible to build a frame around the picture. The standard value of n is 0.
• \wbmbitspixeln: defines the number of bits per pixel for a bitmap (default value is 1).
• \wbmplanesn: specifies the number of bitplanes (default is 1).
• \wbmwidtbbytesn: specifies the length of the bitmap in bytes

You "re here because you have a file that has a file extension ending in .rtf. Files with the file extension .rtf can only be launched by certain applications. It"s possible that .rtf files are data files rather than documents or media, which means they"re not meant to be viewed at all.

what is a .rtf file?

Files in the RTF extension are text documents that can be created, opened, viewed, edited or modified using popular word processing applications for both Mac and Microsoft Windows-based computers. Some of these word processing programs are Microsoft WordPad for Windows and Microsoft Word 2011 for Mac. RTF files provide users with wide cross compatibility support, which was the main objective for the development of the Rich Text Format technology, and these .rtf files can even be opened, viewed and used with database applications. The content of RTF files may include blocks of text with bold or italicized alphanumeric characters and symbols as well as a wide variety of typefaces. Images, tables or charts may also be embedded into these RTF files, and text documents saved in the .rtf extension have support for many font types and styling or formatting attributes. Some of these functionalities are no longer supported by Microsoft Word 2010, most likely because Microsoft decided to discontinue further development on the technology used for these RTF files.

how to open a .rtf file?

Launch a .rtf file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that"s meant to open your .rtf file will open it. It"s possible you may need to download or purchase the correct application. It "s also possible that you have the correct application on your PC, but .rtf files aren't yet associated with it. In this case, when you try to open a .rtf file, you can tell Windows which application is the correct one for that file. From then on, opening a .rtf file will open the correct application.

applications that open a .rtf file

Microsoft WordPad

Microsoft Word

Microsoft Word is a word processor program that is packed in the Microsoft Office Suite . It is developed by Microsoft Corporation, generating a .doc file extension when the file is saved. A document file format (.doc) is a text or binary file format for saving documents on a storage media, mainly for computer use, like typing text, charts, tables, page formatting, graphs, images and other documents whose content is created and edited. Contents of these documents are printable in any sizes and are capable to open in other devices provided that its operating system is able to read DOC files. This .doc file extension has become extensive de facto standard for office documents, but it is an owned format and is not always totally supported by other word processors. A variety of programs that is able to open this type of file, and different operating systems and have installed programs that can open a 1ST file are: Microsoft Word, Microsoft Notepad, Microsoft Word, IBM Lotus WordPro, and Corel WordPerfect.

Microsoft Notepad

Microsoft Notepad

Notepad is a basic text editor used to create plain documents. It is commonly used to view or edit text (.txt) files, and a simple tool for creating Web pages, and supports only the basic formatting in HTML documents. It also has a simple built-in logging function. Each time a file that initializes with .log is opened, the program inserts a text timestamp on the last line of the file. It accepts text from the Windows clipboard. This is helpful in stripping embedded font type and style codes from formatted text, such as when copying text from a Web page and pasting into an email message or other “What You See Is What You Get†text editor. The formatted text is temporarily pasted into Notepad, and then immediately copied again in stripped format to be pasted into the other program. Simple text editors like Notepad may be utilized to change text with markup, such as HTML. Early versions of Notepad offered only the most basic functions, such as finding text. Newer versions of Windows include an updated version of Notepad with a search and replace function (Ctrl + H), as well as Ctrl + F for search and similar keyboard shortcuts. It makes use of a built-in window class named edit. In older versions such as Windows 95, Windows 98, Windows Me and Windows 3.1, there is a 64k limit on the size of the file being edited, an operating system limit of the EDIT class.

Microsoft Works

Microsoft Works

Microsoft Works is an incorporated package software that was developed by Microsoft. It is less expensive, smaller, and has fewer features than Microsoft Office or other office suites. Its central functionality includes a word processor, a spreadsheet and a database management system. Newer versions have a calendar application and a dictionary while older versions included a terminal emulator. Files with WPS extension is utilized for output files of the Microsoft Works word processing application. These files are classified as text documents that can be created, saved, viewed and edited using the Microsoft Works program. Microsoft Word 2010, Microsoft Publisher 2010, Planamesa NeoOffice, and OxygenOffice Professional are some of the applications that are able to open and view the content of these WPS files. The contents of these WPS files can also be exported to other compatible word document formats. this promotes convenience and efficient document presentation, group collaboration and sharing between users of different systems and word processing applications; however, WPS document cannot be applied with macros and other formatting options available in Microsoft Word; so Microsoft discontinued support and development of the Microsoft Works application with its version 9 and the release of Microsoft Word 2010.

notepad2

The Notepad2 application is a more advanced text editor for Windows developed by Florian Balmer. This program originated from the original built-in Microsoft Notepad which is why it is also effective and fast even when it is small. Notepad2 also has a lot of features such as syntax highlighting that allows a text or a source code to be displayed using different fonts and colors. This syntax highlighting feature of notepad2 allows users to write programming language easily and distinctly. This amazing function of Notepad2 is also owing to several other features it possess such as auto indentation, regular and expression-based find and replace feature, bracket matching, newline conversion, encoding conversion as well as multiple undo and redo features. These features make the function of the simple Notepad more advanced and it makes Notepad more interesting to use either to open files in - The extension (format) is the characters at the end of the file after the last dot.
- The computer determines the file type precisely by extension.
- By default, Windows does not show filename extensions.
- Some characters cannot be used in the file name and extension.
- Not all formats are related to the same program.
- Below are all the programs with which you can open the RTF file.

Rich Text Format (RTF)

This format was defined by Microsoft as the standard format for exchanging text documents. Therefore, this format is similar in purpose to the SYLK format for spreadsheets. RTF is supported by many Microsoft products. For example, since version 2.0, it has been introduced into Windows as a Clipboard format, which makes it possible to exchange data between various Windows applications. In addition, the RT format is supported by WORD for Macintosh from version 3.X and WORD for PC from version 4.X.
RTF only uses character-representable codes from the ASCII, MAC, and PC character sets for document exchange. In addition to text, the file in RT format contains control commands in a readable form.
The document consists mainly of control commands for setting up a reader for files in RTF format. These commands can be divided into control words and control symbols.
The control word is a sequence of characters with a separator (delimiter) at the end:
\lettersequence
The control word is preceded by a backslash "\" (backslash). The following characters can be used as delimiters:
Ш Space (space), and this character refers to the control word;
Digit or "-" sign. These characters must be followed by a delimited parameter. A space or other characters, except for numbers and letters, can be used as a separator;
All characters other than numbers and letters. These characters do not belong to the control word.
The RT format uses the letters "A" through "Z" and "a" through "z" and the numbers "0" through "9" to specify the escape sequence. National characters do not apply to control information.
Individual letters are used as control characters. Each control character is preceded by a backslash "\":
\control symbol
Only a few of these symbols are currently defined. Therefore, unknown characters may be skipped when reading.
In the RT format, it is possible to combine individual sequences into groups using brackets:
(group start
) end of group
Such groups are created, for example, when describing footnotes, headers and footers, etc. If you want to place the characters "\", "(" or ")" inside plain text, then they must be preceded by a backslash:
\\
\{
\}.
This allows a program reading an RTF sequence to recognize that the character should not be interpreted as a control character.
The RT format also uses some character codes to control printing.
Code Meaning
09H Tabulator
0AH Symbol CR
0CH Symbol LF
CR and LF characters within text will be skipped. Microsoft uses these characters for greater clarity when presenting an RTF file. Inside the control words, the characters CR and LF can have a special meaning, more about this will be discussed in the description of the commands.

Special control words
RTF has special-purpose control words. Below are these words and their meaning.

\chpgn
The change page number control word outputs the current page number.
\chftn
The change footnote control word activates automatic footnote numbering.
\chdate
With change date you can display the current date.
\chtime
With change time you can display the current time.
\chatn
Link to note (text follows in a group).
\chftnsep
Indicates a change in the line separating footnotes from text.
\/
This sequence is used to enter the text of the formula.
\:
Indicates a sub-item of an index.
\*
Text may be skipped when reading RTF format.
\~
Specifies a hard (non-breaking) space between two words, i.e. in this position, the sentence cannot be split when wrapping to the next line.
\-
The symbol denotes a soft hyphen (nonrequired hyphen).
\_
The symbol denotes a non-breaking hyphen, where the word cannot be split.
\"hh
The sequence allows direct input of hexadecimal numbers in the text. They are given instead of the characters hh.
\page
This sequence sets the transition to a new page.
\line
This sequence causes a line break in the text.
\par
With the help of this sequence, the end of a paragraph is marked in the text. The \par sequence can be replaced by the \10 or \13 sequence. In this case, \10 corresponds to the ASCII character with code 10 (carriage return). ASCII code 10 (CR) cannot be entered directly because it is ignored by the reader.
\sect
This sequence marks the end of a text fragment or text paragraph.
\tab
This sequence replaces the tab stop. You can also directly set the ASCII code 09H.
\cell
End of table (column).
\row
End of table (row).

The control words described below can be used to perform basic configuration of the RTF reader. They can only occur at the beginning of a document or at the beginning of a group. All operators along with parameters must be enclosed in parentheses, for example:
(\rtf0\pc.......)
The format of some operators is described below.

\rtf<параметр>
Specifies the start of the file. As a parameter, the program that creates the file can specify the version number. For example:
(\rtf0.......)
The label must be at the beginning of the file. This statement may be followed by other statements or a closing parenthesis.
Setting the type of encoding for the saved text is carried out using the following operators:
\ansi: Text is stored in standard ASCII format. This format is used, for example, in Windows.
\mac:. text is stored in Macintosh encoding
\pc: The IBM-PC character encoding is used to display text.
\pca: IBM-PC Code Page 850 (model PS\2).
To transfer texts between different systems, the \ansi encoding must be used.

\colortbl
Windows and other programs use palettes to determine which colors to use. Most often, the palette consists of 16 different colors, obtained by combining the primary colors - red, green and blue. The \colortbl command allows you to change individual palette definitions. For each color, the table indicates the value of the red, green and blue components. Each color is described by three parameters:
\red000
\green000
\blue000
Instead of 000, the value of the color fraction is specified in the range from 0 to 255. Example: in a table consisting of 16 colors, colors 0 and 2 must be redefined. To override colors, the following sequence can be given:
( \colortbl \redl28\green64\bluel28\;;\red0\green64\bluel2 8; )
The color definition ends with a semicolon. Since the 1st color remains unchanged, there are two ";" characters in the sequence follow one after the other. The sequence ends with a closing bracket.
The \cfn operator specifies the background color (with default setting n=0), and the \cbn operator specifies the character color (with default setting n=0).
\fontbl
This operator is used to build a font table and correlates a font name (font group) with a font number. When defining a font, you can use the following operators:
\fnil: Font group name unknown. The output should use a standard font.
\froman: Roman fonts must be used (e.g. Times Roman)
\fswiss: This operator specifies the use of fonts from the Swiss group (Helvetica, Swiss, etc.)
\fmodern: Pica, Elite and Courier fonts can be used.
\fscript: Italic fonts of the Script group are used.
\fdecor: when specifying this operator, fonts must be selected from the Decor group (Old English, etc.).
\ftech: Select a group of fonts with technical and mathematical symbols (SYMBOL, etc.).
The command to create a font group can consist of the following statements:
(\fonttbl\f0\fnil default;)
(\fl\froman roman h;)
(\f2\fswiss helvetica;)
The keyword \fonttbl is followed by the first font number \f0. Next comes the definition of the font group. Here, after the number 0, \fnil is indicated, i.e. group name unknown. The next parameter specifies the name of the font to select (for example, roman h). The default statement tells the reader to use the default font. The font name is followed by a semicolon. In the example above, only fonts numbered 1 and 2 are defined. The entire sequence can be grouped with curly braces.
The font table must be filled with values ​​before the \stylesheet statement or text is encountered. The default font is entered with the \deffn operator.

\stylesheet
This operator defines the font of the paragraph, i.e. the size, style, and name of the typeface, as well as how the text of the paragraph is aligned. It uses two key parameters:
\basedon000: Instead of characters 000, the number of the type of font used as the current one is indicated.
\snext000: Assigns the number of the next font style (style) that will become current.
An operator might look like this, for example:
(\stylesheet\s0\f3\fs20\qj Normal;)
(\sl\f3\fs30\b\qc Heading Level 3;)
Fonts are numbered from 0 to n (\s0...). In the first line, paragraph style 0 (\s0) is named Normal. Text output is done in font 3 (\f3), 10 points in size (\fs20). The \qj parameter says that the inscription should be format aligned. The second line defines font style 1, which is named Heading Level 3. The font is 15 point, bold (\b = bold) and centered (\qc) on output.

\pict
This operator is used when describing a drawing in bitmap format. The following parameters contain the description of the picture as hexadecimal values. Parameters can be selectively used to define the geometry of a drawing or its format:
\pich000: operator specifies the height of the picture in pixels. Instead of three zeros, a numeric value is substituted. If there is no operator, the drawing height is determined from the current drawing data. With the help of the parameter, you can set a certain height for the picture.
\piw000: operator sets the width of the picture in pixels. Everything said about the previous operator is true.
\picscaled: This operator scales the picture so that it exactly fills the area allotted for it.
\wmetafilen: The parameter specifies that the data is stored in the Windows metafile format. The n parameter specifies the metafile type (1 = MM-text).
\macpict: Specifies that the data is stored in Macintosh Quick-Draw format.
\bin000:. parameter specifies the number of bytes. Instead of three zeros, a hexadecimal number is written.
\wbitmapn: parameter specifies the format of the bitmap. The n parameter specifies the type (0 corresponds to a logical bitmap).
\brdrs: defines a simple frame for the picture
\brdrdb: Specifies a double border for the picture.
\brdrth: Specifies a bold line for the picture frame.
\brdrsh: Specifies a shaded frame for the picture

\piccroptn: describes the top margin of a picture in twips. If the parameter n is positive, the upper part of the picture is cut off. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
\piccrorbn: Describes the bottom margin of a picture in twips. For positive values ​​of the n parameter, the lower part of the picture is cut off. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
\pisrporrn: Describes the right margin of a picture in twips. With positive values ​​of the n parameter, the picture is cut off on the right. Negative values ​​of n make it possible to draw a frame around the picture. The default value of n is 0.
\piccropln: Describes the left margin of a picture in twips. If the parameter n is positive, the picture is cut off on the left. Negative values ​​of n make it possible to build a frame around the picture. The standard value of n is 0.
\wbmbitspixeln: Specifies the number of bits per pixel for a bitmap (default is 1).
\wbmplanesn: Specifies the number of bitplanes (default is 1).
