Description

SupportsPartialTransparency indicates whether the graphic supports partial transparency or an alpha channel. 

Some TGraphic descendants, such as TBitmap and TPngImage, can support partial transparency or an alpha channel. When a graphic that supports partial transparency is drawn on a canvas using DrawTransparent, it should be blended with the pixels on the canvas based on the value of the alpha channel.
