gstretchblt xDest yDest wDest hDest xSrc ySrc wSrc hSrc Rop
This is a simple wrapper function for the Windows BitBlt () function. The source parameter for the BitBlit()
function is g_hdcLoad. This Device context, (and associated Bitmap), are loaded using the gloadimage
function.
Arguments:
xDest, yDest = Destination coordinates in device context / bitmap created with gopen.
wDest, hDest = Width and Height of destination bitmap after copy. (in pixels)
xSrc, ySrc = Source coordinates in secondary device context / bitmap created with gloadimage.
wSrc, hSrc = Width and Height of source bitmap to copy. (in pixels)
Rop = Raster bit manipulation operation for copying the bitmap.
