I'm working on a project. This project uses a library someone else created which relies on a couple classes in System.Drawing.Imaging. Problem is, System.Drawing.Imaging does not seem to exist. VS shows the project as referencing System.Drawing, and the using directive for System.Drawing seems to work fine. It's just Imaging that doesn't want to work right. This library is in the form of source code, not a DLL, if it makes a difference.
