Graphics32 provides fast operations for pixels and graphic primitives and is almost a hundred times faster in per-pixel and about 2–5 times faster in drawing lines access than the standard components by Embarcadero which are wrappers for the Windows GDI. Additionally, it provides alpha blending, anti-aliasing as well as filters for resampling and deforming bitmaps.

Features

edit

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)
  • Bitmap resampling with high quality reconstruction filters (e.g. Lanczos, Cubic, Mitchell)
  • Flexible supersampling implementation for maximum sampling quality
  • Flicker-free image displaying components with optimized double buffering via advanced MicroTiles based repaint optimizer
