Recycle a surface previously created with gf_surface_attach()
#include <gf/gf.h>
int gf_surface_reattach( gf_surface_t surface,
int w,
int h,
int stride,
const gf_palette_t * palette,
uint8_t * ptr,
unsigned flags );
- surface
- The handle of the surface that was created with gf_surface_attach()
- w, h
- The new height and width of the surface, in pixels
- stride
- Number of bytes per scanline in the new memory buffer
- palette
- A pointer to a gf_palette_t structure, which represents the new surface palette. You may pass NULL if the surface format is not palette-based (GF_FORMAT_PAL8), or if you don't want to change the palette associated with the surface.
- ptr
- A pointer to the new memory buffer containing image data.
- flags
- Flags affecting the surface properties. None are defined; pass 0.
gf
This function recycles a surface that was previously created with gf_surface_attach(). This function allows a different region of memory to be associated with the specified surface. The format of the data must remain the same.
This function is designed to be fast, and avoids re-allocation of memory in situations where you want to re-use a surface repeatedly.
- GF_ERR_OK
- Success.
- GF_ERR_PARM
- The characteristics of the specified palette didn't match the palette that was originally passed to gf_surface_attach()
