Enumeration

VipsRegionShrink

Declaration

enum Vips.RegionShrink

Description [src]

How to calculate the output pixels when shrinking a 2x2 region.

Images with alpha (see vips_image_hasalpha()) always shrink with VipsRegionShrink and pixels scaled by alpha to avoid fringing.

Set the image interpretation to VipsInterpretation to treat all bands equally.
