Should scale in PDF creation cause errors?

0 votes
asked Jan 3 in Bug by Adam L

I was trying to track down what was causing errors in creating a PDF in a large diagram. I found an errant 'scale' that was the issue. 

The problem does happen under a Windows shell, not just cygwin, with GRAPHVIZ_DOT set to the EXE.
