DrawImage()

void           DrawImage (poImage, nSrcX, nSrcY, nDestX, nDestY, 
                          nWidth, nHeight);

SGLImage*      poImage;
               The SGLImage that will be drawn.

int            nSrcX;
               X coordinate relative to the upper left corner of
               the SGLImage to copy from.

int            nSrcY;
               Y coordinate relative to the upper left corner of
               the SGLImage to copy from.

int            nDestX;
               X coordinate relative to the upper left corner of
               the SGLPixmap to copy to.

int            nDestY;
               Y coordinate relative to the upper left corner of
               the SGLPixmap to copy to.

int            nWidth;
               Width of the rectangular area to be copied.

int            nHeight;
               Height of the rectangular area to be copied.

DrawImage() draws a section of an SGLImage into the SGLPixmap associated with this SGLDrawContext. This area is defined by nSrcX, nSrcY, nWidth and nHeight. It draws this imagery at position nDestX, nDestY of the SGLPixmap.

For efficiency reasons, drawing imagery in the preferred native format is only possible with nSrcX and nSrcY both set to 0.

The output is clipped to the area of the SGLPixmap.
