vips_sink_tile (
VipsImage* im,
int tile_width,
int tile_height,
VipsStartFn start_fn,
VipsGenerateFn generate_fn,

Description [src]
Loops over an image. generate_fn is called for every
pixel in the image, with
the reg argument being a region of calculated pixels.
Each set of pixels is tile_width by tile_height pixels (less at the
image edges). This is handy for things like writing a tiled TIFF image,
where tiles have to be generated with a certain size.
