djview4shapes is a fork of djview4 (http://djvu.sourceforge.net/djview4.html). Its purpose is to display the content of common shapes dictionaries contained in DjVu documents. The idea to display the common shapes of a document (to facilitate e.g. transcription and character inventory extraction) and other suggestions were formulated by Janusz S. Bień. The program is developed by Michał Rudolf using some code of Grzegorz Chimosz. The work is supported by the Ministry of Science and Higher Education's grant no. N N519 384036.
