I have some python code to convert an SVG image to a Kicad pcb module silkscreen, however it doesn't work great for polygons that contain cutouts (such as the holes in the characters A, B, Q, etc). It seems like pcbnew does not support having cutouts inside a filled region. I've noticed that bitmap2component works around this by creating infinitely-thin connections from a polygon's outside edge to each of the cutouts, effectively connecting each cutout with the exterior.
The code isn't great, but here's what I've got so far. It's based on the Egg-Bot code (used for driving a two-axis plotter based on SVG files), and I need to figure out what sort of licensing is needed for it based on all the library files used. https://github.com/wayneandlayne/svg2kicadmod Right now you need to pick the desired width and/or height in mm when you run the script, so if you need different sizes of your logo then you need to create several .kicad_mod files. Eventually it would be really great to have support for changing the scaling of the rasterized logo right within pcbnew, so I perhaps having a python plugin for fancy SVG-based board graphics would be neat. -Matthew Beckler Co-founder and Engineer W&L On Fri, Jul 10, 2015 at 11:42 AM, Tomasz Wlostowski < [email protected]> wrote: > On 10.07.2015 18:31, jp charras wrote: > > > AFAIK, boost::polygon is used only to cleanup and mainly to fracture the > > polygons which are created by potrace, and which are outlines and holes > > inside outlines. > > Indeed, maybe the custom types (KPolygon) made me think it's more > complicated. > > > > The main application of bitmap2component is creating logos which can be > > printed on a silkscreen layer. > > Most logos come nowadays in a vector format (e.g. SVG).
