Method

VipsImagesequential

Declaration [src] 

int
vips_sequential (
  VipsImage* in,

Description [src]

This operation behaves rather like vips_copy() between images in and out, except that it checks that pixels on in are only requested top-to-bottom. This operation is useful for loading file formats which are strictly top-to-bottom, like PNG.

tile_height can be used to set the size of the tiles that vips_sequential() uses. The default value is 1.

Optional arguments

  • tile_height: gint, height of cache strips
