Digital printing system and process using compact trapezoidal representations

摘要

A system and process for digital printing processes commands to draw a trapezoidal image by initially rendering those commands into an intermediate representation based on pixel rows. Depending on the dimensions of the trapezoid or the regularity of the offset of the end pixels of each pixel row from the end pixels of an adjacent pixel row, data representing the trapezoid are sent to a display list as either individual pixel data, pixel row data, or a compact grouping of data derived from the intermediate representation.
