The current graphics/vigra port does not include support for PNG images. It's not clear why, since building the port from source works correctly, and PNG is one of the default formats. This is a follow-on from bug 228547.
Created attachment 200129 [details] patch testbuilds on 13a+i, 12a, 11.2a are fine.
TODO: need to test dependencies
Build-tests done, run-tested of some of the dependencies: editors/openoffice-4 editors/openoffice-devel (untested) editors/libreoffice graphics/hugin graphics/enblend graphics/lprof-devel (untested) math/saga
