One of our friends continues work on the SVG importer and would like to add a possibility of importing graphics as filled polygons. I see there are two ways of handling polygons: - DRAWSEGMENTs of S_POLYGON type - ZONE_CONTAINER placed on non-copper layers
We need to pick one. In order to have the graphics importer return simply a list of DRAWSEGMENTs, I would prefer to use the first method. As far as I can tell, currently DRAWSEGMENT polygons are used only by the microwave tools (and IMHO in a very inappropriate way, as they create DRAWSEGMENTs on copper layers, but that is a separate discussion). It requires a few changes for e.g. correct bounding box & hit test computation, but I can handle it myself. There are no changes to the file format, but given the code lacks basic support for polygon DRAWSEGMENTs, it is not going to be work nicely with old revisions. Are there any objections to following this way? I believe if we agree, then the file version should be bumped to force the users to update KiCad. I also wonder if we could have one more DRAWSEGMENT type to handle polylines as well, so imported vector graphics could be handled as a single instance instead of many individual segments. Maybe it would be even better to add generic support for grouping items, but that is a larger task. Regards, Orson
