Image Processing in VB. A complete rewrite of the 2001 version. Read all uncompressed BMPs, GIF, JPG and PNM files. Write BMP, GIF and PNM files. Also capture/return external Bitmaps and StdPics. Extended Color Depth/Palette options. Dithers enhanced. New Blue Noise Dither. More than 20 new operations - including alphablending and color combination, Sharpen, Blur, Edge, Equalization, and color correction. Particular support for very large BMPs >16M in size. The compiled .dll is many times quicker than in the IDE. Apps using previous (2001)version will require checking and recompilation.
