I've got some code which opens and processes a large tiff file (a bit over 2GB with around 1000 frames in).
This works fine on Windows 7 x64 but fails with an overflow error on XP x64.
Other software (including the windows image browser) has no such problem.
Is there something I can do to make my WPF code cope with larger files in XP x64?
using (Stream instream = new FileStream(sourcePath, FileMode.Open, FileAccess.Read, FileShare.Read))
TiffBitmapDecoder tiffInDecoder = new TiffBitmapDecoder(instream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.None);
