[REBOL] Re: Extending button images.
From: ptretter:charter at: 28-May-2001 20:09
extend Extends an image horizontally, vertically, or both. An image is
stretched without affecting its scale. For instance, a button with rounded
ends can be resized without affecting the dimensions of the rounded ends.
This allows a single button bitmap to be reused over a wide variety of
sizes. Two PAIRs are supplied as arguments. The first PAIR specifies the
offset where the image should be extended. It can be horizontal, vertical,
or both. The second PAIR specifies the number of pixels to extend in either
or both directions.
