Method
VipsRegionprepare_to
Declaration [src]
int
vips_region_prepare_to (
VipsRegion* reg,
VipsRegion* dest,
const VipsRect* r,
int x,
int y
)
Description [src]
Like vips_region_prepare(): fill reg with the pixels in area r.
Unlike vips_region_prepare(), rather than writing the result to reg, the
pixels are written into dest at offset x, y.
Also unlike vips_region_prepare(), dest is not set up for writing for
you with vips_region_buffer(). You can
point dest at anything, and pixels really will be written there.
This makes vips_region_prepare_to() useful for making the ends of pipelines.
