Thanks for all the answers. We will find a different solution. Sadly it seems there is nothing to do with PDN.

Hi there When opening a TIFF file, I get this error: System.ArgumentException: Parameter is not valid. at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData) at PaintDotNet.Data.GdiPlusFileType.OnLoad(Stream input) in D:\src\pdn\src\PaintDotNet\Data\GdiPlusFileType.cs:line 127 at PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src\Data\FileType.cs:line 496 at PaintDotNet.Functional.Func.Eval[T1,TRet](Func`2 f, T1 arg1) in D:\src\pdn\src\Base\Functional\Func.cs:line 158 Using v4.0.9 on Windows 7 Pro x64. I can open the TIFF file okay in "Microsoft Office Picture Manager" I uploaded the file here: http://gpsleg.dk/Solsikkeolie.tiff Do tell if you need any more information. Best regards Henrik
