Abstract

A printer driver has a single filter. The filter includes a program for constructing a pipeline consisted of a plurality of stages based on a print ticket. In one or more of the plurality of stages, a content box of print-target data is modified. When the content box is modified, commands respectively indicating affine transformation matrices are generated. The commands are pushed into a command stack. The pushed commands are used for modification of a visual element. Specifically, the affine transformation matrices are multiplied and thereby an integrated transformation matrix is generated. The visual element is modified by multiplying an affine transformation matrix of the visual element by the integrated transformation matrix.
