Hello. I'm looking for an open source graphics utility/library/code that can detect enclosed areas in a .TIFF file and floodfill them with a given color. I would prefer either .NET code or a tutorial on how to do this, or an open source library that I can link into. If that is not available then it would be nice to find a command line utility, or at least a utility that can handle batch jobs. Any suggestions, anybody? Thanks.

The one that immediately comes to mind is ImageMagick. There are bindings for many languages for it as well.

However, the .Net binding, which is externally hosted, seems to be currently 'down' (Google reports the site as being malicious)
