StdBitsprocedure is QuickDraw's standard low-level routine for doing bit and pixel transfer.
PROCEDURE StdBits (VAR srcBits:›BitMap; VAR srcRect,dstRect:›Rect; mode:›Integer; maskRgn:›RgnHandle);
- A bitmap or pixel map containing the image to copy.
- The source rectangle.
- The destination rectangle.
- The source mode for the copy
- A handle to a region acting as a mask for the transfer.
StdBitsprocedure transfers a bit or pixel image between the bitmap or pixel map specified in the
srcBitsparameter and bitmap of the current graphics port, just as if the
CopyBitsprocedure were called with the same parameters and with a destination bitmap equal to
StdBitsprocedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.

CopyBitsprocedure beginning on page 3-108 for a discussion of the destination bitmap and of the
