MGL_putBufferSrcTrans

Copy an offscreen buffer to the specified location with source transparency.

Declaration

void MGLAPI MGL_putBufferSrcTrans(
MGLDC *dc,
int x,
int y,
MGLBUF *buf,
color_t transparent,
int op)

Prototype In

mgraph.h

Parameters

dc | Device context to copy buffer to
x | x coordinate to copy buffer to
y | y coordinate to copy buffer to
buf | Buffer to copy
transparent | Transparent color for the bitmap
op | Write mode to use when drawing buffer

Description

Copies a offscreen buffer to the specified location on the device context with either source or destination transparency.

When transferring the data with source transparency, for pixels in the source image that are equal to the specified transparent color, the related pixel in the destination buffer will remain untouched. This allows you to quickly transfer sprites between device contexts with a single color being allocated as a transparent color.

Note: This function will fail if you attempt to copy a buffer to a device context that is not the device context that the original buffer was allocated for.
