 Posted: Sat Mar 22, 2008 8:01 pm Post subject: Converting a pdf or changing its fonts |
 |
|
I was recently given a pdf file with terrible fonts - everything is blurry and badly aligned (it was most likely scanned). However, KPDF still allows me to select text and copies it properly to the clipboard. This has me wondering: are there any tools that would allow me to either convert this pdf to another format or at least select which font is used for rendering?
Small catch: the pdf contains a lot of mathematical notation, and the conversion has to take care of them properly (converting them to an image would be ok).
I tried pdftohtml, but the html document that it generated contained nothing but underscores.
Thanks. |

You can try or try to convert the pdf into ps with and view with ghostview, gv or other postscript viewers.Not sure if it works with blurred documents.
Otherwise convert your document to ppm format with and let an ocr software (like ocrad or gocr) do the dirty work. I have not tried one of these ocr programs. |

I suppose that your best bet is to try to convert them to ps. But I am no expert in the matter.

I never got any useful result from any orc program under linux, as much as I love open source, ocr still sucks around here. I would be most happy to be wrong. |
