I have a pdf of a book with 248 pages. I wanted to be able to put it on Comic Book ds, so I found a program called PDF2CBR that supposedly converts pdf files to cbr files. I planned to convert the cbr file to a cbds file with pictods. However, when I went to convert the pdf, instead of creating a cbr file, it gave me 248 (the same number of pages in the pdf) "pbm" files. Is there something that I can do with these files, is there some other program I should use, or is this just an impossible process?
