A standard .NET filestream can be opened using FileInfo.OpenWrite(). However, this produces a FileStream which is write-only.

Code:

FileInfo f = new FileInfo(tifOutputPath);
using (FileStream fs = f.OpenWrite())
{
codecs.Save(img, fs, frm, bpp);
}

This is an issue when saving to specific formats (such as TIF), as it's necessary for the filter to read some information back regarding the file. Using a write-only stream doesn't permit this and will cause an exception to be generated. Therefore, use a read-write stream when saving to a FileStream:

Code:

FileInfo f = new FileInfo(tifOutputPath);
using (FileStream fs = f.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
codecs.Save(img, fs, frm, bpp);
}
