In trying to covert by
Code:
        Dim gm As New GraphicsMill.Bitmap
        gm.FormatAutoSelect = True
        gm.LoadFromMemory(imgdata)
        gm.Formats.SelectCurrent("JPEG")
Parameter to this subroutine - [imgdata() As Byte] I get an exception say that PSD is readonly format and cannot be converted. Is there a simple way to do this? Does TIFF conversion work the same. Thanks in advance Tom

Hi Tom, What line are you getting an exception at? In fact the routine should be looking something like this:
Code:
Sub SaveAsJpeg(imgdata() As Byte)
   Dim gm As New GraphicsMill.Bitmap
   gm.FormatAutoSelect = False
   gm.LoadFromMemory(imgdata)

   gm.Formats.SelectCurrent("JPEG") 
   gm.SaveToFile "d:\filename.jpg"
End Sub
Imgdata can contain any file supported with Graphics Mill for loading.

Thanks, code worked fine. New Question, if upload PSD with color space set to adobe98, will GM convert to sRGB before changing JPEG or does it ignore color space in conversion?

JPEG format supports both RGB and CMYK color spaces, and it also can embed color profiles. After it read PSD file, it won't convert anything, but save pixels and color profile as is. However you can force color conversion if you need:
Code:
...
objBitmap.Data.ColorManagement.IsEnabled = True
objBitmap.Data.ColorManagement.RgbProfile = Server.MapPath("sRgb.icc")
objBitmap.Data.ConvertTo24bppRgb
...
Hope this helps.
