CONST_DDBLTFXFLAGS

The CONST_DDBLTFXFLAGS enumeration is used in the lDDFX member of the DDBLTFX type to specify the type of FX operation.

Enum CONST_DDBLTFXFLAGS
    DDBLTFX_ARITHSTRETCHY   =   1
    DDBLTFX_MIRRORLEFTRIGHT =   2
    DDBLTFX_MIRRORUPDOWN    =   4
    DDBLTFX_NOTEARING       =   8
    DDBLTFX_ROTATE180       =  16
    DDBLTFX_ROTATE270       =  32
    DDBLTFX_ROTATE90        =  64
    DDBLTFX_ZBUFFERBASEDEST = 256
    DDBLTFX_ZBUFFERRANGE    = 128
End Enum

DDBLTFX_ARITHSTRETCHY: Uses arithmetic stretching along the y-axis for this blit.
DDBLTFX_MIRRORLEFTRIGHT: Turns the surface on its y-axis. This blit mirrors the surface from left to right.
DDBLTFX_MIRRORUPDOWN: Turns the surface on its x-axis. This blit mirrors the surface from top to bottom.
DDBLTFX_NOTEARING: Schedules this blit to avoid tearing.
DDBLTFX_ROTATE180: Rotates the surface 180 degrees clockwise during this blit.
DDBLTFX_ROTATE270: Rotates the surface 270 degrees clockwise during this blit.
DDBLTFX_ROTATE90: Rotates the surface 90 degrees clockwise during this blit.
DDBLTFX_ZBUFFERBASEDEST: Adds the lZBufferBaseDest member of the DDBLTFX type to each of the source z-values before comparing them with the destination z-values during this z-blit.
DDBLTFX_ZBUFFERRANGE: Uses the lZBufferLow and lZBufferHigh members of the DDBLTFX type as range values to specify limits to the bits copied from a source surface during this z-blit.
