PutMonoImageMSBBM
Draws a monochrome bitmap stored in system memory with bus mastering
Declaration
void NAPI GA_2DRenderFuncs::PutMonoImageMSBBM(
N_int32 x,
N_int32 y,
N_int32 width,
N_int32 height,
N_int32 byteWidth,
N_uint8 *image,
N_int32 imagePhysAddr,
N_int32 transparent)
Prototype In
snap/graphics.h
Parameters
x |
Destination X coordinate to draw the bitmap at |
y |
Destination Y coordinate to draw the bitmap at |
width |
Width of the bitmap in pixels |
height |
Height of the bitmap in pixels |
byteWidth |
Width of the bitmap in bytes |
image |
Pointer to the bitmap image data to draw |
imagePhysAddr |
Physical address of bitmap image data in system memory |
transparent |
1 for transparent, 0 for opaque |
Description
This function copies a monochrome bitmap image from a system memory buffer to video memory using the hardware accelerator, which is used for fast bitmap masking and font rendering operations. The bitmap is rendered in the specified colors using the currently active mix. This function is identical to PutMonoImageMSBSys, except that the bitmap data transferred to video memory using a bus master DMA operation, and the imagePhysAddr is the physical memory address of the image in system memory (and the bitmap data must be physically contiguous in memory).
