Question

i have problems during creating image from stream. on my windows pc it forks great, on ubuntu server, it throws an error

System.ArgumentException: A null reference or invalid value was found [GDI+ status: InvalidParameter] at System.Drawing.GDIPlus.CheckStatus (System.Drawing.Status) <0x00157> at System.Drawing.Image.CreateFromHandle (intptr) <0x00027> at System.Drawing.Image.LoadFromStream (System.IO.Stream,bool) <0x0002b> at System.Drawing.Image.FromStream (System.IO.Stream,bool,bool) <0x00013>

I checked System.Drawing library setup on my server, it says that system.drawing is installed

mono-test-install

Answer 1

First, locate the directory where is the System.Drawing.dll file (for example /opt/mono-4.4.0/lib/gac/System.Drawing/4.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll).

Create a file in the same directory called System.Drawing.dll.config with the following content, updating the directory to the correct location of libgdiplus.so:

<configuration>
  <dllmap dll="gdiplus.dll" target="/opt/mono-4.4.0/lib/libgdiplus.so"/>
</configuration>
