Generic imaging library originally designed for AfterStep
libAfterImage is the imaging library implemented for AfterStep X Window Manager. It has been generalized to be suitable for any application in need of robust graphics engine. It provides facilities for loading images from files of different formats, compressed in memory storage of images, scaling, tinting/shading, flipping and superimposition of arbitrary number of images over each other. In addition it allows for linear gradients drawing, and antialiased/smoothed text drawing using both FreeType library and X Window fonts. Primary goals of this library are to achieve exceptional quality of images and text, making code fast and small at the same time. Additional steps are taken to compensate for screen colordepth limitation, and different error diffusion algorithms are used to provide for smooth images even in low colordepth modes.
