[bug-pcl] image conversion with matrix

[Yang Xin]

Hi:

  In PostScript Reference, there exist parameter 'matrix' to help to convert
image, such as zooming in/out, deforming, and rotating image. Then, how
should I do if I want to achieve these conversions of images in PCL? Can
it be achieved only using PCL or GL2 commands?
