VipsRegionShrink
Description [src]
How to calculate the output pixels when shrinking a 2x2 region.
Images with alpha (see vips_image_hasalpha()) always shrink with
VIPS_REGION_SHRINK_MEAN and pixels scaled by alpha to avoid fringing.
Set the image interpretation to VIPS_INTERPRETATION_MULTIBAND to
treat all bands equally.
