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.

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.
