Declaration
void NAPI GA_2DRenderFuncs::BitBltColorPattLin(
N_int32 srcOfs,
N_int32 srcPitch,
N_int32 srcLeft,
N_int32 srcTop,
N_int32 width,
N_int32 height,
N_int32 dstLeft,
N_int32 dstTop,
N_int32 rop3)
Prototype In
snap/graphics.h
Parameters
srcOfs |
Offset of source bitmap in video memory |
srcPitch |
Pitch of source bitmap in bytes |
srcLeft |
Left coordinate within source bitmap to copy |
srcTop |
Top coordinate within source bitmap to copy |
width |
Width of the rectangle in pixels |
height |
Height of the rectangle in scanlines |
dstLeft |
Left coordinate of destination |
dstTop |
Top coordinate of destination |
rop3 |
Microsoft ROP3 code for the copy (GA_rop3CodesType) |
Description
This function is identical to the regular BitBltLin function, except that it also applies the currently active 8x8 color pattern to the destination. The source data, pattern data and destination data are combined together according to the value passed in the rop3 parameter.
