Invalid bounding box computation for path #174

Closed yaqwsx closed 2 years ago

yaqwsx commented 2 years ago

Hello, I have a number of cases where the paths have an invalid bounding box (it is absurdly large in one direction):

I guess this could be related to #171

Hi @yaqwsx, can you give me an SVG file containing one of the curves so that I can visually check that this curve exists? Earlier versions of svgpathtools may have been correcting the arc (in a case where no such arc existed) and that might explain the gigantic bounding box.

I created a test file with one such arc and got an error that no such arc exists. test

Unfortunately, I didn't save any inputs back then. However, I bumped the dependency in PcbDraw, and so far, I haven't found a file that would trigger this behavior. So I think we can consider this resolved. Thanks!
