Hi,
This has been bothering me for a while:
I like to generate a PDF of the enroute charts and print it later in order to take a paper copy as a backup to my iPad.
The generated PDFs are MASSIVE in size. It takes ages to open them - the different layers are built up individually in the Adobe Reader and on slow computers (such as often found at flight schools, rental outfits) will never open. It also takes ages to print them and sometimes, some layers (or colors?) or omitted, resulting in unusable print outs (after spending half on hour getting the printer to print them).

Has this been noted before? Is there going to be a better implementation of the PDF printing feature?
Regards

Patrick

Because printing APIs do not work that way. We send vector data to the print subsystem in order that the printed output is as high-quality as possible. We do not have control over how specific print-to-PDF tools may work, but it's very possible you may be able to find one which would perform the step you suggested of converting all output to a resolution-limited bitmap. You would undoubtedly lose quality of course, but that is your decision. We really can't do anything to help from within SkyDemon, sorry.

The document you uploaded is unusable on a Mac as well - which has the leanest and quickest PDF viewing engine I've ever come across. It took several minutes to open and was then impossible to navigate around. I had to terminate the application in the end.

Your PDF printing tool is producing nasty output I'm afraid. It is turning any areas with translucency into a heavily dithered high resolution bitmap. Unfortunately, lots of stuff on a typical SD chart has an element of translucency.

As already suggested, the next step would be to try some different PDF printing software.

Okay, thanks, all - when I find an external solution (e.g. a better Print2PDF tool), I will post that here.
