Summary

Specifies how the bitmap is displayed.

Pascal

 published property DrawMode: TDrawMode;

Description

Specifies how the bitmap should be combined with a background during pixel transfer and similar operations. In dmOpaque mode, new pixels simply replace the background pixels. In dmBlend mode, they are combined using the alpha blending operation. This property is used while copying one bitmap into another, scaling, performing linear transformations etc. The dmCustom mode allows implementation of custom blending functions using the OnPixelCombine call-back event. Blending in dmBlend mode, is performed using Blend or BlendEx functions.
