NAME

       SDL_BlitSurface9Grid  -  Perform a scaled blit using the 9-grid algorithm to a destination surface, which
       may be of a different format.

SYNOPSIS

       #include <SDL3/SDL_surface.h>

       bool SDL_BlitSurface9Grid(SDL_Surface *src, const SDL_Rect *srcrect, int left_width, int right_width, int top_height, int bottom_height, float scale, SDL_ScaleMode scaleMode, SDL_Surface *dst, const SDL_Rect *dstrect);

DESCRIPTION

       The pixels in the source surface are split into a 3x3 grid, using the different  corner  sizes  for  each
       corner,  and the sides and center making up the remaining pixels. The corners are then scaled using scale
       and fit into the corners of the destination rectangle. The sides and center are then stretched into place
       to cover the remaining destination rectangle.

FUNCTION PARAMETERS

       src    the SDL_Surface structure to be copied from.

       srcrect
              the SDL_Rect structure representing the rectangle to be used for the 9-grid, or NULL  to  use  the
              entire surface.

       left_width
              the width, in pixels, of the left corners in srcrect.

       right_width
              the width, in pixels, of the right corners in srcrect.

       top_height
              the height, in pixels, of the top corners in srcrect.

       bottom_height
              the height, in pixels, of the bottom corners in srcrect.

       scale  the  scale  used  to  transform  the  corner of srcrect into the corner of dstrect, or 0.0f for an
              unscaled blit.

       scaleMode
              scale algorithm to be used.

       dst    the SDL_Surface structure that is the blit target.

       dstrect
              the SDL_Rect structure representing the target rectangle in the destination surface,  or  NULL  to
              fill the entire surface.

RETURN VALUE

       for more information.

THREAD SAFETY

       Only one thread should be using the src and dst surfaces at any given time.

AVAILABILITY

       This function is available since SDL 3.2.0.
