Re: [Mono-dev] Problem with PNG transparancy on current Debian Unstable
You could check what version of libgdiplus(https://github.com/mono/libgdiplus) did Debian Squeeze include, and try to run a custom new mono built from sources, with an older libgdiplus, to confirm that it is a libgdiplus regression. If it is, then after that you could try to bisect the commit that caused it. On 09/06/15 11:40, Benjamin Schieder wrote: Hello Alex.

There aren't that many commits for pngcodec.c in the last 4 years (which is when 2.10 was tagged), so it's probably one of those: https://github.com/mono/libgdiplus/commits/master/src/pngcodec.c .

Re: [Mono-dev] Problem with PNG transparancy on current Debian Unstable
Hello Rafael. I have already established that it is most certainly a regression in libgdiplus. Using an older version (2.10) with the current mono runtime by overriding LD_LIBRARY_PATH to the 2.10 libgdiplus binary brings a correct result.
