RTF Font Size Filter

I have a large file orginally stored as a PDF. I was able to use Adobe and save it as a RTF file. So now I have this file in Rich Text Format and the data isn't in a format that makes it easy to extract only certain lines. Except the font sizes. The data I need is currently in 2 different unique font sizes, what I need is an app that will let me strip all text that is a certain font size. Since the work is being done for font size, would also be nice if it would strip out certain font faces as well as an option. Its also important that the order of the data does not change after the fonts are extracted so the data doesn't get jumbled. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Should run on Windows XP at least.
