Projects / Transparency


Transparency is a small, specialized tool for transparent PNG processing on the command line. It focuses on typical tasks for Web design. In the spirit of ImageMagick, it provides special extensions such as conversion of white to transparency, and the preparation of transparent PNGs for perfect GIF export (i.e., "partial" application of the alpha channel).
