[mkgmap-dev] mkgmap:drawLevel and --order-by-decreasing-area

Thu Nov 24 06:57:46 GMT 2016

Hi Ticker,

thanks for the patch. I was not yet able to reproduce the problem reported by rheinskipper1000.  Do you have a test case for me?

Gerd

Hi Gerd

Attached patch stops the errors from shapeMergeFilter. The java2D
intersect.() / converter used for clipping sometimes generates
flattened shapes which I now check for and chuck away.

I've also moved the code that shares common coord.

The patch is independent of the pending drawLevel patch
