I'm trying to load a bitmap created using the GDIInternals
BitmapHandler.SaveBitmap function but it fails everytime.

The following code is taken from the sample BitmapFun project and
slightly modified to show my issue.

String lsPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetModules()[0].FullyQualifiedName);
// Load gif
Bitmap b = new Bitmap( lsPath + "\\test.gif");

// Get CF internal data structure
InMemoryBitmap bmp = BitmapHandler.GetInMemoryBitmap(b);

// Save bitmap bits to a file
BitmapHandler.SaveBitmap(bmp, @lsPath + "\\out.bmp");

// Load saved bitmap
Bitmap c = new Bitmap( lsPath + "\\out.bmp");


When it attemps to perform the "new bitmap" function on the saved
bitmap, I get the following error -

"An unhandled exception of type 'System.ArgumentException' occurred in
System.Drawing.dll

Additional information: Argument Exception"


However, the bitmap will load fine if viewed on the desktop. Any
clues on how to get around this problem would be greatly appreciated.

Thx
 
Since I wrote that GDIInternals code, I suppose I'm the
one who should take care of this :)
Could you email me the .bmp file that you are getting?
