Description

The GR32.Blend.Modes unit provides an object-oriented framework for custom pixel blending modes and compositing algorithms in Graphics32.

Key features provided by GR32.Blend.Modes include:

• Blender Class Hierarchy: Base abstract classes TCustomGraphics32Blender, TCustomGraphics32ComponentBlender, TGraphics32ComponentBlender, and TGraphics32SeparableBlender for implementing custom blending algorithms.
• Normal Blender: The default TGraphics32BlenderNormal implementation that delegates standard pixel blending to Graphics32's fast core routines.
• Adobe / Photoshop Compositing: TGraphics32ComponentBlender implements the standard Adobe Photoshop separable alpha compositing formula for multi-layer color blending.
• Global Blend Service: The Graphics32BlendService singleton and related interfaces (IGraphics32BlendService, IGraphics32BlendGroups, IGraphics32BlendGroup, IGraphics32BlendEnumerator, IGraphics32BlendGroupsEnumerator) enable dynamic registration, enumeration, and discovery of blend modes and blend groups across Photoshop, Porter-Duff, and extra blend mode libraries.
