Abstract
Vector graphics may be flexibly resized. Pins are associated with vector graphics control points, and when a canvas is resized, the pin locations are scaled according to the canvas resizing, and the control points associated with the pin are scaled according to a different positioning scheme. Pins may be fixed in location relative to the pin location, or may scale only in one direction. Control points not associated with a pin are scaled according to the canvas resizing. Other embodiments allow regions to be defined, in which control points are governed by a different positioning scheme, or allow a grid lines to be drawn defining the canvas into slices, where each slice is assigned a specific positioning scheme.
