Where can I get giflib/libungif?

http://prtr-13.ucsc.edu/~badger/software/libungif.shtml

Can I build Ilib with MS Visual Developer Studio?

Yes, it has been successfully built using MS Developer Studio on Windows NT. You must setup your own project for this.

Can I build Ilib with Cygnus' Win32 GCC?

I get a bunch of X11-related link errors. What's that all about?

Version 4.0 of GifLib requires you to add -lX11 to LIBS and all the makefiles. (Version 3.X did not require this.)

What's the purpose of the font2h utility?

The font2h utility allow you to embed a font within the application's executable so that you do not need to distribute the BDF font file with the executable.

Do you accept patches/modifications?

You bet... Just email any patches to cknudsen@radix.net.

What are some of the features that can be added?

• Add new drawing functions:
  • IDrawArc()
  • IFillArc()
• Better routines for converting 24-bit images to 8-bit images.
• Add support for True Type (scalable) fonts -- this will allow text to be drawn at angles
• Add support for more file types:
  • Read/Write PNG (including alpha transparency)
  • Read XPM
  • Read/Write XBM
  • Read/Write BMP
  • Write PostScript
• Any other useful clients that could be packaged with Ilib (squid traffic reporter generator, etc.)
