DeeBook is a universal IE based ebook decompiler.
Developed with Visual C++ 6.0, should be upgraded to later versions of Visual Studio with minor modification.
Open ebook, locate its content area with DeeBook, then click "Decompile" button. Of course, you can adjust some settings before decompiling.
All images are captured from screen directly, so there are some limitations.
Can not save images with transparent background.
Can not save animated GIF images.
It's better to maxmize ebook window to ensure images can be captured without being cropped.
