Relates to issue #17 -- The current version does not implement the new Gerber file format features.

  • Step and Repeat (SR) -- closing with M02 is deprecated. It should close with "%SR*%".
  • Block Aperture (AB)
  • Change "Level Polarity" to "Load Polarity" (LP)
  • Load Mirroring (LM)
  • Load Rotation (LR)
  • Load Scaling (LS)

  • The block apertures and new step-and-repeat model should increase the hierarchy of the Form XObjects. Pretend that they are apertures, seeing as the file format also does this, but this new kind of aperture can use other apertures to draw with.
  • The LR, LM and LS can use PDF transformations before calling the XObject, but that means that the bounding box must update with special care...
  • When using LM, LR and LS on code D01 (draw lines and arcs), the rectangular aperture should get special attention.
