Centering objects in resize mode seems to be broken about pdfscale HOT 2 CLOSED

Digging to the Ghostscript release notes indeed showed that a major changes has been implemented recently. It seems like the rewritten PDF interpreter has caused the issues mentioned above.

As a workaround adding the flag -dNEWPDF=false will force Ghostscript to still make use of the old PDF interpreter written in PostScript rather than C.

That obviously isn‘t a perfect solution as the reimplemented interpreter should do the trick as well — however it at least keeps everything as it should be for now.

Sorry for the late reply. This is interesting.

I wonder:

1. If there is a way to enable the new parser and get the same results
2. If using -dNEWPDF=false on older GS versions will break the script (we need to test the version before using it if that is the case)

I will need to investigate...
