Browser PDF WYSIWYG Editor/VIewer

Hi, The project is an in-browser WYSIWYG editor with a look and feel of a simple document editor, that can be exported to PDF at back-end. The editor should be able to view PDF that was created by it, keeping it consistent with the previous edit. Specifics: * MUST be modular, Object-oriented, so it can be modified easily and thus documented in comments inside the code. * MUST include a definite edit area that looks like an A4 document (horizontal). * MUST include a button for adding text * MUST include a button for adding image (JPEG, PNG) * MUST include an option for columns for text (CSS3 Multi-column). * Text MUST be wrapped along a border of an added image. * MUST be consistent, the EDIT->PDF->VIEW chain should be EDIT==VIEW. * PREFERABLY (not necessarily) utilizing HTML5. * PREFERABLY (not necessarily) not to be heavily based on others' code. * DOES NOT NEED to be pretty, just plain and clear. * DOES NOT NEED to be compliant with IE9 Fun and challenging project, who's up for a bid?
