Graphics32

Graphics32 is a library designed for fast 32-bit graphics handling on Delphi and Kylix. Optimized for 32-bit pixel formats, it provides fast operations with pixels and graphic primitives, and in most cases Graphics32 outperforms the standard TCanvas classes. It is almost a hundred times faster in per-pixel access and about 2–5 times faster in drawing lines.

Features Some of Graphics32 features include:

    * Fast per-pixel access up to 100 times faster compared to standard TBitmap;
    * High-performance Bitmap alpha blending (including per-pixel alpha blending);
    * Pixel, line and polygon antialiasing with sub-pixel accuracy (combined with alpha blending);
    * Arbitrary polygon transformations and custom fillings;
    * Bitmap resampling with high quality reconstruction filters (e.g. Lanczos, Cubic, Mitchell);
    * A unique state-of-the-art rasterization system;
    * Affine transformations of bitmaps: rotations, scaling, etc with sub-pixel accuracy;
    * Arbitrary projective transformations of bitmaps;
    * Arbitrary remapping transformations of bitmaps (e.g. for Warping, Morphing);
    * Flexible supersampling implementation for maximum sampling quality;
    * Flicker-free image displaying components with optimized double buffering via advanced MicroTiles? based repaint optimizer;
    * Multiple customizible easy-to-use overlay layers;
    * Locking of bitmaps for safe multithreading;
    * A property editor for RGB and alpha channel loading;
    * Design-time loading of image formats supported by standard TPicture;
    * Works on Borland Delphi, C++ Builder and Kylix.
