Welcome to the index of the tutorials for the library BGRABitmap. You can browse tutorials by number with the bar on the top, or by the following categories :

Install BGRABitmap and draw basic shapes

The images of TBGRABitmap have drawing functions using floating point coordinates or integer coordinates.

Textures and scanners

Pixels are a table in memory containing values in the format TBGRAPixel. We can at this level do various operations.

Other drawing contexts

It is possible to have other contextes, in order to have other basic drawing functions.

Auxiliary classes

More classes, to be created for use, are also available.

  • TBGRATextEffect, in unit BGRATextFX, allows to prepare the drawing of text line, to add effects like contour and shadow.
  • TBGRALayeredBitmap, in unit BGRALayers, allow to create a multi-layered bitmap. Units BGRAPaintNet and BGRAOpenRaster contain implementations to read and write in Paint.NET format (read only) and OpenRaster format (read and write).
  • Units BGRAGradientScanner and BGRATransform contain scanners to do various effects.
  • Unit BGRAGradients contain procedures to generate gradients and TPhongShading class for Phong shading.
  • TBGRACompressableBitmap, in unit BGRACompressableBitmap, allow to store and compress images.

Other units contient low level functions, and you should not need to use them for a normal usage.
