Demo for composition modes

+ +

+ This demo shows some of the more advanced composition modes supported by Qt. +

+ +

+ The two most common forms of composition are Source and SourceOver. + Source is used to draw opaque objects onto a paint device. In this mode, + each pixel in the source replaces the corresponding pixel in the destination. + In 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 Thomas Porter and Tom Duff. See the QPainter documentation + for details. +
