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.
