详细说明： Graphics32 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 ble nding (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. As of version 1.5.1b Graphics32 is licensed under the terms of the Mozilla Public License. ...展开收缩
