E-XD++ Enterprise Edition -- Product Information

16. Dual-cache drawing (Double buffer drawing)

E-XD++ uses dual-cache (also called "Double buffer") drawing mode, and tracks view with virtual frame when editing. These avoid flashing when drawing and editing, and also improve the effect of refreshing.

You can disable Double Buffer simply by calling the following function in class CFOPCanvasCore:

void EnableMemory(
// FALSE to disable double buffering
BOOL bEnable
);
