QCad PDF export creates huge files

Postby ringstrom » Mon Sep 03, 2007 8:28 pm

For a drawing that uses splines, e.g. by using the standard font, the exported PDF files are huge. I found a way to work around that in Linux. If the files are printed to a (PDF) file in Linux, the files are much smaller. For the two of my drawings that I checked, which both contain a moderate amount of text, the difference is 573% and 657%, respectively.

The reason for the difference comes from the fact that the printed, small, PDF:s contain splines, but the PDF:s exported via the PDF export function in QCad only contain straight lines, so each spline in the drawing is represented by a large number of straight lines.

Another drawback of the large PDF:s, apart from size alone, is that they take much longer to display and print.

I'm using QCad Professional version on both Linux and Windows.

Yes, this depends on the PDF Export implementation the toolkit use. It is maybe better in Linux then Windows.

Maybe linked to different versions of Qt (from trolltech.com)
