The recommended way to render arbitrary images/fonts in gerber (and AFAIK the approach used by every CAD supporting truetype fonts in gerber) is using horizontal rasters. Usually the raster pitch is wide as the aperture or maybe half of it for better edge quality; also the raster approach actually follows the mechanics of the silkscreen process (which *is* done on a raster of wires...) I did a proof-of-concept demo some year ago (about when we switched from the 'squared' font) but the idea wasn't pursued for lack of interest (and display performance reasons, too). Another reason is that the plotting infrastructure need to implement text in postscript/PDF too and that is even more tricky than gerber. -- Lorenzo Marcantonio Logos Srl -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/668145 Title: Font preferences not available anymore, internal font changed To manage notifications about this bug go to: https://bugs.launchpad.net/kicad/+bug/668145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
