rtf2html's Introduction

1.  Overview

    This is RTF to HTML converter version 0.1.0.
    Copyright (C) 2003 Valentin Lavrinenko, [email protected]
    
    Its primary purpose is using by developers to add rtf to html 
    converting functionality to their projects, although, end users 
    can also find it useful.

    The main effort was made on processing the tables correctly, and it
    seems successful - all other programs I've seen do tables processing
    much worse. Moreover, at the moment, I haven't seen any file that
    displays correctly in MS Word, but crashes this program.
    
    For further information, go to
    http://www.sourceforge.net/projects/rtf2html


2.  Copying

    Distributed under LGPL license - see COPYING.LESSER, it must be 
    in the archive.


3.  Compiling

    - Under UNIX:
      Just ./configure && make && make install. The program seems
      to work much (about 2 times) faster when compiled with STLPort
      STL implementation than with the GNU one. So, you may use
      --with-stlport configure option if you have it installed.

    - Under MS Windows:
      Use MSYS/MinGW, use it the same way as in UNIX.
      No makefiles for other Win compilers are included yet, so,
      write it yourself, if you want - it isn't that hard.
      BCC is no longer supported!

4.  Installation

    No binary distribution for Unix/Linux is provided - just
    compile the program from source (see above). You can, however,
    download a binary package for MS Windows from the project page,
    http://www.sf.net/projects/rtf2html.

5.  Usage

    5.1 Command-line options

        rtf2html -v|--version

	prints the current version.

	rtf2html -h|--help

	prints the help.
    
        rtf2html [<rtf file> [<html file>]].
    
        Converts the file. If either of files is not specified, 
	the corresponding std descriptor (stdin or stdout) is used.

    5.2 Supported features

        This version supports the following:
        - Character formatting: bold, italic, underline, sub- and superscripts.
         NOTE: underlining is displayed only as solid.
        - Paragraph formatting: horizontal alignment, indentation, margins.
        - Table formatting: arbitrary cell spans, cell sizings, borders, 
          vertical alignment in cells.
         NOTE: borders are displayed correctly only under IE 5+ and only 
               as solid.
        - Page formatting: page width, left margin.
        - Hexadecimal character codes (Cyrillic letters would come out in 
          win1251)
        - Font faces and sizes.
        - Foreground and background colors, highlighting.
    
    5.3 Unsupported features

        This version DOES NOT support the following:
	- Character sets.
	- Hyperlinks.
        - Images.
        - Different stuff like macros, embedded OLE objects, etc.


6.  Compiling notes.

    The source was compiled with 
    - gcc 3.3 under ALT Linux Master 2.4 on i386
    - gcc 3.4.2 (MinGW) under Win2k

rtf2html's Issues

Using on Windows

How to use rtf2html on windows? I downloaded the file .EXE but isn't working for me

tabs and blank space

If there are tabs or spaces at the beginning of a line, they are removed.
The same if they are between words.

Missing diagrams in html translation of LZXFMT.DOC

Translating LZXFMT.DOC from https://archive.org/details/cab-sdk with both rtf2html and unrtf --html misses diagram sections.

intro

disclaimer: I'm not opening these issues asking for some solution;
actually I'm very grateful for the existence of rt2html because of all the thing I tried, it is the only one that really produces proper html output. These issues may be known, or not, but since I'm not able to correct these at the time I'm posting for posterity. Right now I'm just running the windows binary - one day I may find the time to read the code and see if there is something I can add even though I'm not very skilled programmer

so why am I opening these issues?

to say thank you, because it's really proven helpful!
to show some activity because at least for me issues/wiki entries indicate a piece of software that has been tested by other users
to point out a few quirks and (some patchy solutions I've done)

Issue description

It doesn't properly treat \uXXX? characters. In my RTF files at least, the XXX are decimal representations of a unicode one.

workaround

The tool is properly treating\'XXencoded characters (it ignores the codepage, but in my case it's okay since I'm expecting it to always be Windows 1253/ISO 8859-7(greek)).
I'm preprocessing the file, replacing all the \uXXX? characters with their Windows 1253 equivalent. Of course some times (particularly when the characters encoded are not in the range of Windows 1253) it won't map properly, but for my scenario it's acceptable and rare.

Some crashes occur when fuzzing rtf2html.

Image support

Can you please add Image support? This project would be perfect for what I need to use it for then.
