Graphics32 is a graphics library for Delphi. Optimized for 32-bit pixel formats, it provides fast operations with pixels and graphics primitives. In most cases, Graphics32 considerably outperforms the standard TBitmap/TCanvas methods.
However, they are rewritten to accelerate and optimize drawing on 32-bit device-independent bitmaps (DIBs). It also includes a few new options.
Features of the Graphics32 library:
- Fast per-pixel access is up to 100 times faster compared to standard TCanvas/TBitmap
- High-performance Bitmap alpha blending
- Arbitrary polygon transformations and custom fillings
- Bitmap resampling with high-quality reconstruction filters
- Affine transformations of bitmaps: rotations, scaling
- Flexible supersampling implementation for maximum sampling quality
- Multiple customizable, easy-to-use overlay layers
- Platform independent code
Graphics32 has some important differences from the standard components. It does not heavily rely on Windows GDI; most of the functions are reimplemented and optimized specifically for 32-bit pixel format.
Here is some sample code from the Graphics32 ArrowHead example:
