CONST_DDCAPS1FLAGS

The CONST_DDCAPS1FLAGS enumeration is used by the lCaps, lNLVBCaps, lSSBCaps, lSVBCaps, and the lVSBCaps members of the DDCAPS type to describe hardware capabilities.

End Enum

DDCAPS_3D: The display hardware has 3-D acceleration.
DDCAPS_ALIGNBOUNDARYDEST: DirectDraw supports only those overlay destination rectangles with the x-axis aligned to the lAlignBoundaryDest boundaries of the surface.
DDCAPS_ALIGNBOUNDARYSRC: DirectDraw supports only those overlay source rectangles with the x-axis aligned to the lAlignBoundarySrc boundaries of the surface.
DDCAPS_ALIGNSIZEDEST: DirectDraw supports only those overlay destination rectangles whose x-axis sizes, in pixels, are lAlignSizeDest multiples.
DDCAPS_ALIGNSIZESRC: DirectDraw supports only those overlay source rectangles whose x-axis sizes, in pixels, are lAlignSizeSrc multiples.
DDCAPS_ALIGNSTRIDE: DirectDraw creates display memory surfaces that have a stride alignment equal to the lAlignStrideAlign value.
DDCAPS_ALPHA: The display hardware supports alpha-only surfaces. (See alpha channel)
DDCAPS_BANKSWITCHED: The display hardware is bank-switched and is potentially very slow at random access to display memory.
DDCAPS_BLT: Display hardware is capable of blit operations.
DDCAPS_BLTCOLORFILL: Display hardware is capable of color filling with a blitter.
DDCAPS_BLTDEPTHFILL: Display hardware is capable of depth filling z-buffers with a blitter.
DDCAPS_BLTFOURCC: Display hardware is capable of color-space conversions during blit operations.
DDCAPS_BLTQUEUE: Display hardware is capable of asynchronous blit operations.
DDCAPS_BLTSTRETCH: Display hardware is capable of stretching during blit operations.
DDCAPS_CANBLTSYSMEM: Display hardware is capable of blitting to or from system memory.
DDCAPS_CANCLIP: Display hardware is capable of clipping with blitting.
DDCAPS_CANCLIPSTRETCHED: Display hardware is capable of clipping while stretch blitting.
DDCAPS_COLORKEY: Supports some form of color key in either overlay or blit operations. More specific color key capability information can be found in the lCKeyCaps member.
DDCAPS_COLORKEYHWASSIST: The color key is partially hardware assisted. This means that other resources (CPU or video memory) might be used. If this bit is not set, full hardware support is in place.
DDCAPS_GDI: Display hardware is shared with the GDI.
DDCAPS_NOHARDWARE: There is no hardware support.
DDCAPS_OVERLAY: Display hardware supports overlays.
DDCAPS_OVERLAYCANTCLIP: Display hardware supports overlays but cannot clip them.
DDCAPS_OVERLAYFOURCC: Overlay hardware is capable of color-space conversions during overlay operations.
DDCAPS_OVERLAYSTRETCH: Overlay hardware is capable of stretching. The lMinOverlayStretch and lMaxOverlayStretch members contain valid data.
DDCAPS_PALETTE: DirectDraw is capable of creating and supporting DirectDrawPalette objects for more surfaces than only the primary surface.
DDCAPS_PALETTEVSYNC: DirectDraw is capable of updating a palette synchronized with the vertical refresh.
DDCAPS_READSCANLINE: Display hardware is capable of returning the current scan line.
DDCAPS_VBI: Display hardware is capable of generating a vertical-blank interrupt.
DDCAPS_ZBLTS: Supports the use of z-buffers with blit operations.
DDCAPS_ZOVERLAYS: Supports the use of the DirectDrawSurface7.UpdateOverlayZOrder method as a z-value for overlays to control their layering.
