The pages-per-dict option specifies the number of pages to be included in a shared dictionary file (*.djbz). The value you assign to this option represents the number of pages you want to include in a shared dictionary. For most documents, a value of 20 is the maximum before file size is no longer affected. Some documents, such as hand-drawn images, do not gain from shared dictionaries because they do not contain repeating shapes. For these types of documents, a value of 1 should be used to disable the use of shared dictionaries. The default value for this option is 10.
