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_reorder_prepare_many()
to attempt to
reorder computations to minimise recomputation.
