Various technologies described herein pertain to filling a fill area of a canvas with a source visual object and/or a supplemental visual object to emulate a result of clamping the source visual object onto the fill area of the canvas. A source sub-region of a canvas is filled with the source visual object. Moreover, an extension sub-region of the canvas, which includes at least a part of the fill area outside the source sub-region, is formed based on the source sub-region of the canvas. Further, a supplemental visual object is generated by using a tiling clip on the source visual object and repeated within the extension sub-region of the canvas. The tiling clip specifies a size of the portion of the source visual object used as the supplemental visual object.
