Quality problem with rendering a plot in PDF and JPG/PNG

Postby Celia » Tue Jun 16, 2026 11:11 am

Hello,


When I want to export my light plot in PDF, the image of PDF file that I exported to work on, moves, the file doesn't look like the one that I saved on LX Free.

If I try to export in PNG or JPEG, the quality is really bad, and blurry.

How can I have a proper and clean export of my plots ?

Thank you,

Celia

There is not built-in operating system support on Windows and Linux for PDF like there is on MacOS. So, LXPlan uses open source libraries for PDF export. The quality of import and export using these libraries can vary depending on the exact content, especially when it comes to fonts and text. The latest version of LXPlan, 3.0.0 (20619.1), replaces the older PDF libraries that had been used since LXFree for Java (which was renamed to LXPlan to prevent confusion). The newer libraries may improve your experience exporting a PDF directly from LXPlan.

The other option on Windows is to use the File->Print command and to "Print" to a PDF file. Depending on the size of your drawing, you might want to create a custom paper size to fit the drawing all on one page when exporting a PDF by using the Print command.
