Delphi,Kylix,Lazarus开源图像处理库Graphics32

官网：http://graphics32.org

Graphics32 is a library designed for fast 32-bit graphics handling on Delphi, Kylix and Lazarus. 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 Embarcadero RAD Studio, Delphi, C++ Builder and Kylix (The last version that supported Kylix was 1.8.3). Also Lazarus is supported.
