Description [src]

This macro returns a pointer to a pixel in an image, cast to a VipsPel *. It only works for images which are fully available in memory, so memory buffers and small mapped images only.

If VIPS_DEBUG is defined, you get a version that checks bounds for you.

This function is not directly available to language bindings.

A VipsImage.

X

Type: -

X coordinate.

Y

Y coordinate.
