When the Filehandler's methods refer to pages, they are indexed from 1, i.e. the first page is page 1 etc. Other modules should *never* read directly from the files pointed to by paths given by the FileHandler's methods. The files are not even guaranteed to exist at all times since the extraction of archives is threaded. cCs­t|_d|_||_d|_tidddti ƒ|_ g|_ d|_ g|_ h|_h|_tiƒ|_d|_tidtiƒ|_|iƒdS(Ntprefixscomix.tsuffixs!\.(jpg|jpeg|png|gif|tif|tiff)\s*$(tFalset file_loadedtNonet archive_typet_windowt _base_pathttempfiletmkdtemptostsept_tmp_dirt _image_filest_current_image_indext_comment_filest _raw_pixbufst _name_tabletarchivet Extractort _extractort _conditiontretcompiletIt _image_retupdate_comment_extensions(tselftwindow((sK/home/sork/Pontus/Programmering/Python/Comix/comix-4.0.4/src/filehandler.pyt__init__$s          cCs}||ijob|i|dƒy$tii|i|ƒ|i| from cache.
