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.
