ExactImage is a fast C++ image processing library.
Unlike ImageMagick, it allows operation in several
color spaces and bit depths natively, resulting in
much lower memory and computational requirements.
Some optimized algorithms operate in 1/20 of the
time ImageMagick requires, and displaying large
images can be as fast as 1/10 of the time the
“display” program takes.

Changes:
A PCX and Targe decoder were added. The external API ImageCropRotate was fixed to accept negative values, and the font methods now accept an optional font filename. An off-by-some error was fixed for drawing text on vector paths. An external API was added to create, stroke, and fill arbitrary vector paths. A method was added to directly create synthetic images. The fastAutoCrop method was improved to auto-crop any solidly filled color. The HOCR HTML parser was improved to parse and accept more tags. Support for mirroring of RGBA data as well as setting colors with alpha value was added.
