DREnableSemiTransparentOverlay

Syntax

LONG DREnableSemiTransparentOverlay (BOOL bNewVal)

Description

DREnableSemiTransparentOverlay() enables a semi-transparent display of the Direct3D overlay area.

In semi-transparent mode, the values of the camera image and the overlay data are added up for each pixel. Since black has the value 0, the complete camera image will be visible if the overlay is black; if the overlay is white, only the overlay will be visible. With all other colors, the camera image will be visible with the overlay superimposed.

Hinweis

The key color has no effect in semi-transparent mode.

TRUE to enable semi-transparent overlay
