The C++ Bitmap Library consists of simple, robust, optimized and portable processing routines for the 24-bit per pixel bitmap image format.

The library has the following capabilities: * Read/Write 24-bit Bitmap Images * Pixel, row or column level batch editing * Colour conversions (RGB,YCbCr) in byte and floating values * Highly optimized subsample and upsample (resizing) * Various colour maps (1000 levels - autumn, copper, gray, hot, hsv, jet, prism, vga, yarg) * Texture generation (checkered pattern, plasma) * Graphics drawing interface (line, line-segment, rectangle, triangle, quadix, horizontal and vertical line-segments, ellipse, circle, plot pixel, pen width, pen colour) * Cartesian canvas and associated drawing interface * PSNR and Image comparisons * Simple nearest colour match from set of colours * Wavelength to RGB approximations * Single header file solution requires no installation or building
