Graphics32 Is A Powerful Drawing Library To Enhance Your Delphi Windows Apps


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 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:

Other drawing examples include:

  • AntiAliasing
  • ArrowHead
  • Benchmark
  • Blurs
  • Clipper
  • CubicSpline
  • Curves
  • GammaBlur
  • GammaCorrection
  • GradFills
  • GradLines
  • GradSampler
  • Grow
  • LineStippling
  • Lion
  • MeshGradients
  • Polygons
  • RenderText
  • ScatterPlot
  • SvgPath
  • TextVPR
  • VertexReduction
