Save Screenshot to PDF fails
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Whenever you try to save a screenshot to a pdf format, you get an error that simply says "Save Image failed." To replicate, simply select "File -> Save Screenshot", accept defaults for save options, and then save in PDF format.
Unless this is super-easy to fix, I recommend simply removing the PDF option from save screenshot. If you want to save a PDF, using Export Scene is a much better option.
