Hello,
I would like to write and read metadatas from PNG files, I've succefuly done the task with pngcs.dll library ([link][1]) but I've tryied to build the project for iOS and it doesn't works, the library is not compatible, or I don't know, the error message is this:
ArgumentException: The Assembly ICSharpCode.SharpZipLib is referenced by Pngcs ('Assets/Pngcs.dll'). But the dll is not allowed to be included or could not be found.
UnityEditor.AssemblyHelper.AddReferencedAssembliesRecurse (System.String assemblyPath, System.Collections.Generic.List`1 alreadyFoundAssemblies, System.String[] allAssemblyPaths, System.String[] foldersToSearch, System.Collections.Generic.Dictionary`2 cache, BuildTarget target) (at /Users/builduser/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:156)
UnityEditor.AssemblyHelper.FindAssembliesReferencedBy (System.String[] paths, System.String[] foldersToSearch, BuildTarget target) (at /Users/builduser/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:194)
UnityEditor.HostView:OnGUI()
And the build process (in Unity) terminate with this error message:
Error building Player: Extracting referenced dlls failed.
So, exists a way to make this dll works or another way to store/read metadatas from pngs?
Thanks
