Method
VipsImagereorder_margin_hint
Declaration [src]
void
vips_reorder_margin_hint (
VipsImage* image,
int margin
)
Description [src]
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_image_prepare_many() to attempt to reorder
computations to minimise recomputation.
