Another more recent application for the bitmap conversion tool is to help recreate a board design using a scanned image of a plot such as a scan of some pages from a magazine or an old Gerber plot printed on paper for documentation. An image is created on one of the ECO layers and this image can be included in the project, tracks and pads can be drawn, and then the image deleted. I made small changes to the tool a long time ago since a number of people asked for the feature, but as typical I never received any feedback.
Personally I think we should maintain a bitmap conversion tool; I don't believe that using another vectorization tool will be a good idea because people don't want to install many other support tools and expect the EDA package to provide all the tools they would need. If that were not the case we wouldn't even be talking about features like the MCAD exports, we'd simply tell users "use this other external software and follow these complicated procedures." We would have to change the name to 'EDNA' for Electronic Design Non-Automation. Going back to the topic of rebuilding boards from bitmap images, my personal preference (if I had the time for it) would be to have an intelligent program which uses feature recognition to create the PCB data with a little help from the user, but since such reengineering work is rare and it would take a year or more full time to get to a usable state, such a tool never made it into my list of things to do. - Cirilo On Sat, Jul 11, 2015 at 2:42 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).
