Vips.Image.reorder_margin_hint (original) (raw)

vips_reorder_margin_hint() sets a hint that image contains a margin, that is, that each vips_region_prepare() on image will request a slightly larger region from it’s inputs. A good value for margin is (width * height) for the window the operation uses.

This information is used by vips_reorder_prepare_many() to attempt to reorder computations to minimise recomputation.
