Abstract: A piece of artwork defined using a vector image format can be customized by the consumer. The consumer can select patterns to be applied to the shapes of the artwork as well as manipulate the appearance of the patterns once applied to the shapes. The manipulations can include translation, rotation, scaling, and inversion of the patterns. The manipulations that a consumer makes can be recorded so that they can be reapplied to a version of the artwork having a desired size. Multiple shapes can be grouped to facilitate applying and manipulating a pattern consistently across the grouped shapes. Relative values for manipulations can be generated to facilitate applying the manipulations consistently across versions of the artwork that have different aspect ratios.
