Export script for .jpg and/or .tif

Question

hi,
i'm quite proficient with java script and action script - now also getting into scripting illustrator. i'd like to write a script to export each layer of an open document as a separate .jpg and/or .tif file.
apparently though, there is no way to access the resolution depth property (i need 300dpi) or the format method property (i need baseline optimized).
can that really be true? only 72dpi output possible? no full property access?
thanks a lot for any hint, maybe there are some strange workarounds?
