Hmm, while I'm not certain, we may be talking about the same thing, but from a different standpoint. I don't see any reference in the gerber spec to the word "raster". If you are talking about drawing straight lines with an apeture to to rasterize your own image, I'm wondering if this falls into the catagory of "stroke painting" which unamco is claiming to be "harmful" (see the PDF named "Gerber File Format: Painting Considered Harmful" on the page http://www.ucamco.com/downloads.aspx). However, it was my understanding that a modern photoplotter would take your contour regions and rasterize them to produce the final output, leaving you to just draw what you need in as simple of terms as possible and let the plotter rasterize it. Please correct me if I'm misunderstanding something here. ** Bug watch added: code.google.com/p/fritzing/issues #1568 https://code.google.com/p/fritzing/issues/detail?id=1568 -- 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
