In this mode, + each pixel in the source replaces the corresponding pixel in the destination. + In \b{SourceOver} composition mode, the source object is transparent and is + drawn on top of the destination. + + In addition to these standard modes, Qt defines the complete set of composition modes + as defined by X. Porter and Y. Duff. See the QPainter documentation for details. +*/ |
