You can take pretty much any image, insert it into a OO/L.Office file, export it as a PDF which anyone can read - if you want to ‘extract’ text/images from a file, that may be a different animal - I used to scan documents for some people then chuck the image into a Libre office document and export it to PDF, makes the doc’ readable by anyone and a lot smaller for emailing if that’s an issue. HTH
If you mean OCR (Optical Character Recognition) there are a couple of free ones … but believe me when I say you’ll spend more time correcting their mistakes than just typing it out in the first place (even if you only have one finger)
I gather their is commercial OCR for Linux, but as in Windows it may not be cheap … indeed it may be more expensive as it’s aimed at the enterprise. http://www.ocr4linux.com/en:pricing
Thanks guys! It seems like it might be my mistake… :-[
I’d assumed the recipient would be opening the file in a Windows environment - seems she has some sort of tablet? I’ll get my wife to re-send the mail with the attached image in it’s original format (.ppm I think) and see if that works?
