Image fromstream issue

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

Your have a working System.Drawing setup

any ideas?

According to MSDN, classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. This is documented here:
http://msdn.microsoft.com/en-us/library/system.drawing.aspx
If this is what's causing the problem, you have at least 2 alternatives: Either use Windows Imaging Components, or use an imaging toolkit with web support such as Leadtools.
