Description Dante Ashton 2009-07-17 16:13:15 UTC 
Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    Unspecified Linux

Ocrad ( http://www.gnu.org/software/ocrad/ ) is an Optical Character Recognition backend. It allows for images containing text to be turned into machine readable characters.

Not all .pdfs come with selectable text, this limits both the usefulness of such files and it's potentional auidance. 

If OCR software is incorperated, Okular could link in with Kttsd and read the document out for disabled users.

Because it could make images into machine readable text, it would also improve the functionailty of NEPOMUK and Scribo.

Yes, it could be a pretty nice feature. I'm using KBookOCR right now, and although exporting the text to an editor (Writer) is quite usefull, the ability to recognize text inside the PDF could be quite useful.

ocrad is a very nice software, inserted into distribution. It worked very well with kooka. Would it be difficult to insert it into Okular?  
Thank you.

Here is a comparative of software disagreement of recognition of characters.

Hoping to be a help. Thank you.

Frankly .pdf seems to be a very poorly conceived format in the first place.  It's very limiting in many ways.  Often working with it is very problematic.
