The user can then choose to print the diagrams or export them to any of these vector and bitmap formats: BMP, EPS, GIF, Graphviz, JPEG, PNG, PostScript, SVG, TIFF, Visio VDX, or VML. Mac users can also export to these additional formats: JPEG2000, OpenEXR, Photoshop, PDF, Quickdraw, Silicon Graphics or TGA. Windows users can also export to the EMF (Enhanced Metafile) format.

code2flow is an experimental script which sweeps through your project source code, looking for function definitions, then does another sweep, looking for where those functions are called. It connects the dots and presents you with a flowchart estimating the functional structure of your program. It is especially useful for untangling spaghetti code and getting new developers up to speed. code2flow is experimental and meant to provide a rough overview of the structure of simple projects. Source code which is just a little esoteric will break this. Even with normal code, there are many known limitations and many outright bugs.
