VipsRegioninvalidate

Declaration [src]

void
vips_region_invalidate (
  VipsRegion* reg
)

Description [src]

Mark a region as containing invalid pixels. Calling this function means that the next time vips_region_prepare() is called, the region will be recalculated.

This is faster than calling vips_image_invalidate_all(), but obviously only affects a single region.
