Below is the documentation of those functions from the source. There is
lots of example code in src/demos/nanox/
If you're still confused, please ask more specific questions.
/**
* GrNewPixmap:
* @width: the width of the pixmap
* @height: the height of the pixmap
* @addr: currently unused in client/server mode
* @Returns: the ID of the newly created pixmap
*
* Create a new server side pixmap (an offscreen drawing area which can be
* copied into a window using a GrCopyArea call) of the specified width and
* height.
*/
GR_WINDOW_ID
GrNewPixmap(GR_SIZE width, GR_SIZE height, void *addr)
/**
* GrCopyArea:
* @id: the ID of the drawable to copy the area to
* @gc: the ID of the graphics context to use when copying the area
* @x: the X coordinate to copy the area to within the destination drawable
* @y: the Y coordinate to copy the area to within the destination drawable
* @width: the width of the area to copy
* @height: the height of the area to copy
* @srcid: the ID of the drawable to copy the area from
* @srcx: the X coordinate to copy the area from within the source drawable
* @srcy: the Y coordinate to copy the area from within the source drawable
* @op: the ROP codes to pass to the blitter when performing the copy
*
* Copies the specified area of the specified size between the specified
* drawables at the specified positions using the specified graphics context
* and ROP codes. 0 is a sensible default ROP code in most cases.
