C Declaration Method

typedef BITBLTINFO *PBITBLTINFO;

Fields

ulLength(ULONG) Length of the BITBLTINFO data structure, in bytes.

ulBltFlags(ULONG) Flags for rendering of rasterized data.

Miscellaneous flags used by the graphics engine for rendering of rasterized data:

BF_DEFAULT_STATE Blt direction is left to right and top to bottom.

BF_DIR_X_NEGATIVE Blt direction is towards X origin.

BF_DIR_Y_NEGATIVE Blt direction is towards Y origin.

BF_ROP_INCL_SRC ROP includes a source bit map.

BF_ROP_INCL_PAT ROP includes a pattern bit map.

BF_SRC_TRANSPARENT Source transparent involved. SRC will not change when SRC=BG_COLOR.

BF_DST_TRANSPARENT Destination transparent involved. DST will not change when DST=BG_COLOR.

BF_PAT_TRANSPARENT Pattern transparent involved. Pattern not involved when PAT=BG_COLOR.

BF_PAT_SOLID Pattern is solid; all Foreground color.

BF_PAT_HOLLOW Pattern is hollow (empty); no Foreground color.

BF_APPLY_BACK_ROP Treat ROP as Foreground mix and MonoBackROP as Background mix.

BF_SRC_MONOINVERT Zero (0) bits are Foreground on monochrome SRC bit map.

BF_PAT_MONOINVERT Zero (0) bits are Foreground on monochrome PAT bit map.

BF_SR_BITS_EXTERNAL Source bit map bits are in a nondevice-specific format.

BF_LAST_BLT Defines last blit in a banded BitBlit.

BF_SRC_Y_FLIP Source Y coordinates are inverted relative to device origin.

cBlits(ULONG) Count of Blts to be performed.

ulROP(ULONG) Raster operation.

ulMonoBackROP(ULONG) Background mix if B_APPLY_BACK_ROP is set.

ulSrcFGColor(ULONG) Monochrome source Foreground color.

ulSrcBGColor(ULONG) Monochrome source Background color and transparent color.

ulPatFGColor(ULONG) Monochrome pattern Foreground color.

ulPatBGColor(ULONG) Monochrome pattern Background color.

abColors(PBYTE) Pointer to color translation table.

pSrcBmapInfo(PBMAPINFO) Pointer to source bit map (#BMAPINFO)

pDstBmapInfo(#PBMAPINFO) Pointer to destination bit map (BMAPINFO).

pPatBmapInfo(PBMAPINFO) Pointer to pattern bit map (BMAPINFO).

aptlSrcOrg(PPOINTL) Pointer to array of source origin #POINTLs.

aptlPatOrg(PPOINTL) Pointer to array of pattern origin POINTLs.

abrDst(#PBLTRECT) Pointer to array of Blt rects.

prclSrcBounds(PRECTL) Pointer to source bounding rect of source Blts.

prclDstBounds(PRECTL) Pointer to destination bounding rect of destination Blts.
