BitBltPattSys
Copy a block of system memory to video memory, with a mono pattern applied
Declaration
void NAPI GA_2DRenderFuncs::BitBltPattSys(
void *srcAddr,
N_int32 srcPitch,
N_int32 srcLeft,
N_int32 srcTop,
N_int32 width,
N_int32 height,
N_int32 dstLeft,
N_int32 dstTop,
N_int32 rop3,
N_int32 flipY)
Prototype In
snap/graphics.h
Parameters
srcAddr |
Address of source bitmap in system 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) |
flipY |
True if the image should be flipped vertically |
Description
This function is identical to the regular BitBltSys function, except that it also applies the currently active 8x8 monochrome pattern to the destination. The source data, pattern data and destination data are combined together according to the value passed in the rop3 parameter.
