gf_draw_blit2()

Blit an area from one surface to another

Synopsis:

#include <gf/gf.h>

int gf_draw_blit2( gf_context_t context,
                   gf_surface_t ssurface,
                   gf_surface_t dsurface,
                   int          sx1,
                   int          sy1,
                   int          sx2,
                   int          sy2,
                   int          dx,
                   int          dy );

Arguments:

context
The handle for the draw context to blit.
ssurface
The handle of the surface containing the source pixels. If NULL, the context's currently targeted surface is used.
dsurface
The handle of the destination surface to copy to. If NULL, the context's currently targeted surface is used.
sx1, sy1
The coordinates of the upper-left corner of the source area to blit from.
sx2, sy2
The coordinates of the lower-right corner of the source area to blit from.
dx, dy
The coordinates of the offset point on the display to blit the area to.

Library:

gf

Description:

This function copies the area defined by src, from the source surface to the same-sized area in the destination surface, offset by dst. If the source and destination surfaces are the same, overlapping blits are supported.

Note: The destination rectangle is subject to clipping only if the destination surface is the surface currently targeted by the context (or NULL). Otherwise the destination rectangle is subject to the boundaries of the destination surface. The source rectangle is subject only to the boundaries of the source surface.

Returns:

GF_ERR_OK
Success.
GF_ERR_PARM
Invalid source rectangle.
GF_ERR_NOLOCK
The Hardware isn't locked; check to ensure gf_draw_begin() was called successfully.
