Need to use gdiplus API in standalone

Hi,
I’m using Aspose.Slide.dll to convert powerpoint shapes and slides to textures. It works fine inside the editor but when i publish a standalone it says : DllNotFoundException: gdiplus.dll

i have found libgdiplus.dylib in Program File(x86)/Unity/Editor/Data/mono/lib/ but no gdiplus.dll in …/Data/mono/lib/mono/2.0/

Does anyone know how to include that gdiplus.dll in the build or any workaround to make it work like a wrapper or something?

Ok,
I forgot to mention that on Win7 it works but all fonts are renderer with Arial even if i have define another one.
The “DllNotFoundException: gdiplus.dll” is show when i run a mac version build (and nothing more happen) (i’llgo for that issue later…)

It looks like it’s about installed fonts on the computer.
Inside UnityEditor, installed fonts are accessible but not in standalone build.

Any idea?
