Rendering differences: Export as image and Print (to PDF) #321

Open guitorri opened 9 years ago

guitorri commented 9 years ago

Exporting to image seems to render diagrams better than Print (and setting the output to a PDF). The rest of the schematic looks better on the Print output. The line thicknesses (dash spacing) and aliasing seem to be different depending on the print/export method. I wonder if we can be more consistent.

See screenshots for the two outputs.

OTOH, I was wondering if it makes really sense to have an Export as... and Print... (in the main menu) which almost do the same thing.

The first picture seems to have anti-alias enabled, but using integer coordinates for the drawing, so the schematic comes out blurred (it reminds me of a similar effect I saw when working on the anti-alias stuff some months ago)

I think it makes sense to have both. Print is really meant for accessing the system printer settings. The Export as image does not actually print. Maybe we change the later to Export as... and then handle all the export types we might have in a custom dialog.

Export as image at first creates SVG and the passes it to inkscape in batch mode. Print uses QPainter. Inkscape is one of the best packages for publication-ready graphics preparation. And it provides the best quality of output.
