libpng versions
Hey all,
I have an app that is building from unity 4.1.5 and is using Scaleform for UI. (I mention scaleform because I think its the likely cause at this point).
I'm trying to take a screenshot of the application during an Augmented Reality scene for social sharing.
However when I try to take the screenshot I get this log.
libpng warning: Application built with libpng-1.2.18 but running with 1.5.13
Failed to store screen shot
Now the only sign of any additional libpng stuff I can find in the project is scaleform which looks to include it and add a linker flag to it in the xcode project.
My question is, has anyone had this or a similar libpng issue before? Does anyone have any suggestions as to how I can overcome this issue? or perhaps there is a way of generating a screenshot from unity without it using libpng
Hey FatWednesday,
I've also just encountered this issue.. It seems like Texture2D's EncodeToPNG() function conflicts with Scaleform's code base when building to iOS.
Did you find a solution? I'm thinking I may need to write my own PNG encoder in C#.. :O
I am running into this issue except libpng is just telling me incompatible versions in application and headers. What version of libpng is Unity 4.3.2 using? The headers just need to match and it won't complain any more.
Hope that someone will find this useful as I think it is !!! :)
You can download a fixed Scalefrom package from here: http://forums.autodesk.com/t5/Scaleform-Unity-Development/libpng-screenshots/td-p/4318237
Unity 4.3.2 uses libpng 1.2.18
All you have to do is match the headers from libpng 1.2.18 and Unity is already linked against the library. These errors disappear and you can use libpng.
