CONST_DDFXCAPSFLAGS

The CONST_DDFXCAPSFLAGS enumeration is used in the lFXCaps, lNLVBFXCaps, lSSBFXCaps, lSVBFXCaps, and lVSBFXCaps members of the DDCAPS type to describe driver-specific stretching and effects capabilities, nonlocal-to-local video-memory blit capabilities, system-memory-to-system-memory blit capabilities, system-memory-to-display-memory blit capabilities, and display-memory-to-system-memory blit capabilities.

DDFXCAPS_BLTALPHA

Supports alpha-blended blit operations.

DDFXCAPS_BLTARITHSTRETCHY

Uses arithmetic operations, rather than pixel-doubling techniques, to stretch and shrink surfaces during a blit operation. Occurs along the y-axis (vertically).

DDFXCAPS_BLTARITHSTRETCHYN

Uses arithmetic operations, rather than pixel-doubling techniques, to stretch and shrink surfaces during a blit operation. Occurs along the y-axis (vertically), and works only for integer stretching (×1, ×2, and so on).

DDFXCAPS_BLTFILTER

Driver can do surface-reconstruction filtering for warped blits.

DDFXCAPS_BLTMIRRORLEFTRIGHT

Supports mirroring left to right in a blit operation.

DDFXCAPS_BLTMIRRORUPDOWN

Supports mirroring top to bottom in a blit operation.
