TCombineMode

type TCombineMode = (cmBlend, cmMerge);

Description

TCombineMode defines how drawing operations combine the foreground color with the background.
It also determines how a bitmap is combined with the background when DrawMode is set to dmBlend.

cmBlend - Fast blending of foreground color with the background color using the supplied alpha. This method is not suited for working and preserving alpha-channels. Use this more if you want to blend directly to the display buffer.
cmMerge - Uses a completely different formula that also merges the alpha-channels. This mode is slower than blending but is suited for working with alpha-channels (eg. when composing in temporary buffers).
