CONST_DDBLTFLAGS

The CONST_DDBLTFLAGS enumeration is used in the flags parameter of the DirectDrawSurface7.Blt and DirectDrawSurface7.BltFx methods to determine the valid members of the associated DDBLTFX type. The DDBLTFX type specifies color-key information or requests special behavior from the methods.

Validation flags
DDBLT_COLORFILL: Uses the lFill member of the DDBLTFX structure as the RGB color that fills the destination rectangle on the destination surface.
DDBLT_DDFX: Uses the lDDFX member of the DDBLTFX structure to specify the effects to use for this blit.
DDBLT_DDROPS: Uses the lROP member of the DDBLTFX structure to specify the raster operations (ROPS) that are not part of the Win32 API.
DDBLT_DEPTHFILL: Uses the lFill member of the DDBLTFX structure as the depth value with which to fill the destination rectangle on the destination z-buffer surface.
DDBLT_DONOTWAIT: If the blitter is busy, does not wait for the blitter to become available but returns without blitting.
DDBLT_KEYDESTOVERRIDE: Uses the ddckDestColorKey_high and ddckDestColorKey_low members of the DDBLTFX structure as the color key for the destination surface.
DDBLT_KEYSRCOVERRIDE: Uses the ddckSrcColorKey_high and ddckSrcColorKey_low members of the DDBLTFX structure as the color key for the source surface.
DDBLT_ROP: Uses the lROP member of the DDBLTFX structure for the ROP for this blit. These ROPs are the same as those defined in the Win32 API.
DDBLT_ROTATIONANGLE: Uses the lRotationAngle member of the DDBLTFX structure as the rotation angle (specified in 1/100s of a degree) for the surface.
Color key flags
DDBLT_KEYDEST: Uses the color key associated with the destination surface.
DDBLT_KEYSRC: Uses the color key associated with the source surface.
Behavior flags
DDBLT_ASYNC: Performs this blit asynchronously through the first in, first out (FIFO) hardware in the order received. If no room is available in the FIFO hardware, the call fails.
DDBLT_WAIT: Postpones the DDERR_WASSTILLDRAWING return value if the blitter is busy, and returns as soon as the blit can be set up or another error occurs.
