PDF Printing - OSX vs Windows

[jstarkman]

Hi,

I'm working on an application that prints cards to PDF. It is planned for use on both OSX and Windows. The printing routine basically populates a series of 4 cards with room info on them. It populates card1, prints to PDF, then print break, then does the same for 3 other cards. This process then loops, generating a single PDF for multiple rooms.

The Issue:
For some reason, when printing cards on OSX, it only handles about 50 or 60 rooms (200 - 240 cards) and then crashes. A PDF file for 48 rooms is about 50 MB. On Windows, the same app (not a single change), can handle about 900 rooms (3600 cards) rooms before crashing, and results in a file size of about 100 MB, or about 1/7 the size of the PDF generated under OSX.

Systems: Windows 7 Pro vs OSX Yosemite (brand new MBP with 16G of RAM).

1. Why is the app crashing at all?
2. Why at different points? Is it strictly a RAM thing, or does this represent a memory leak?
3. Why are the PDF file sizes so different? Is there any better PDF library for Livecode that will allow me to optimize the PDF generation under OSX ?

Thanks,

Joel

Hi Joel,

LiveCode shouldn't crash on any platform when generating PDFs so this could suggest a bug. If possible, could you file a report with our Quality Control team @ http://quality.runrev.com and we will be able to investigate further.

As an alternative, there is a PDF library for LC called Quartam PDF library which you may want to try out-
