[cairo] how to copy a rect area from one surface to another

[abhidhnya sonawane]

Hi,

No.
You can specify the starting point of the source,
Try out the code given there.
The main difference is to use cairo_fill instead of cairo_paint.

If you'd like to instead copy some (width, height) rectangle from (source_x,
source_y) to some point (dest_x, dest_y) on the destination you would
instead compute a new position for the source surface origin and then use
cairo_fill instead of cairo_paint:

cairo_set_source_surface (cr, dest_x - source_x, dest_y - source_y)
cairo_rectangle (cr, dest_x, dest_y, width, height);
cairo_fill (cr);

Here:
source_x =starting x-co-ordinate of the source surface.
source_y =starting y co-ordinate of the source surface.

regards,
Abhidhnya.
