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).
