How to create GIF file from other format file in C++

Question

I want to create 2 bits per pixel GIF files in VC environment from a TIFF file.

Is there any free library or maybe source that could help me?

Or how can I do it myself?

Answer 1

Assuming "VC environment" means using VC++ to make a win32 executable:

You could invoke ImageMagick using CreateProcess().

Answer 2

You can use either OpenIL ( http://openil.sourceforge.net/ ), which is a C library, or if you really want a C++ only solution, Magick++ ( http://www.imagemagick.org/www/Magick++/ )
