Rtf2Html 1.3

I recently made a small update to Rtf2Html (the converter I wrote for converting RTF text to HTML markup):

  • Support for conversion to SVG markup
  • Updated preview form to use GeckoFX 29 and XULRunner 29.0.1 (the major version numbers have to match)

Download it here.
Note that this version requires the .NET Framework v4.0 or later.

Rtf2Html SVG support

While you can put the generated SVG text on a page, that wasn’t really my motivation here; what I wanted was a way to import syntax-highlighted text (in my case, typically code) into a vector graphics application (Inkscape, Illustrator, etc.) to be placed as part of a diagram.

Rtf2Html 1.22

New stuff:

  • UI tweaks
  • Removal of block indent (where every line is indented) from pasted RTF text
  • Tweaks for better HTML output (e.g. no more useless span tags containing only whitespace)
  • Accurate preview using XULRunner (via GeckoFX); no longer using the stupid .NET WebBrowser control
  • New logo/icon (I just really hated the old one I made and it was bugging the hell out of me)

The app was designed around the goal of being able to quickly copy and paste snippets of code from Visual Studio (or Netbeans) and turning it into HTML that I could embed in these blog posts; this update stays true to that, and that’s why this app is still so sparse on features, such as conversion of font size or paragraph alignment attributes.

The block indentation removal that now occurs after text is pasted in may be a bit slow. Text in the RichTextBox is selected and altered within the text box itself (it’ll also freeze the UI – if you understand multithreading and WinForms, you know why it’s not simply a matter of spawning off a thread). The alternative is to deal with an RTF parser and edit the RTF input directly, but that’s way more work than I’d care to devote to this app at the moment.

Netbeans RTF Copy plugin

I made a little plugin for Netbeans to allow copying text from the editor as RTF; mainly, preserving the foreground colors from its syntax highlighting. I wanted something akin to what’s possible with Visual Studio.

netbeans copy as rtf

Taking the copied RTF text and running it thru Rtf2Html, I can then post nicely colored code:

header('Content-type: application/xml; charset=utf-8');
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n";

The NBSpecialCopyPaste by Casper Bang was incredibly helpful as a starting point for this plugin.

There’s an issue I wasn’t able to resolve before releasing this; fields (by default, highlighted green by the editor) aren’t copied properly in some cases. The API seems to give no indication that these tokens are colored differently. I know this is true for Java and PHP code, but not true for XML. The code to get the necessary AttributeSet is exactly what’s in NBSpecialCopyPaste:

private static AttributeSet findFontAndColors(Token tkn, FontColorSettings fcs)
AttributeSet as = fcs.getTokenFontColors( );
if (as == null)
// ...try to get from its category
as = fcs.getTokenFontColors(;

return as;

I’ll dig deeper and try to resolve this in a future version.
