HVS ColorGIF 2.0 is a plugin for Photoshop and plugin-compatible paint
programs which produces highly optimized, compact GIFs using the HVS
algorithm. It allows advanced control of color tables, transparency,
dithering, gamma and thresholding. All features are enabled in this demo
for thirty days after installation. Version 2.17 is fully compatbile with
Adobe Photoshop 5, and offers improved color reduction for palettes of
fewer than nine colors.
