[scribus] scribus Digest, Vol 132, Issue 8

Thu Mar 21 16:30:22 UTC 2019

In my uses, I see PDF as something like a fax—a picture of a document. In using optical character recognition to turn PDFs into editable files, I find that some applications are better than others at distinguishing between look-alikes like S and 5, or l and I. Roman fonts seem to work better; sans serif fonts yield more errors. First OCR program I recall was one devised and later spun off by Xerox maybe 20 years ago. Aldus had a good PDF/OCR program, which was folded into Acrobat after Adobe acquired Aldus. Later Adobe provided free Acrobat Reader, renamed Reader, and other companies started providing good OCR apps—Serif, Nuance, to name a couple, and some OCR versions were bundled with scanners and multi-function printers.

Hi both of you,

Thank you for your kindness to answer and comment on my question.

When I got the problem, I used the font Arial. Now I have changed the font in the complete book to Calibri, and the problem is thereby solved. When I now export the pdf-file, there is no problem at all. That shows that you are right when you say that the size of the pdf-file has nothing to do with the problem.

I still do not know why there is a problem with one font and not with another, but as long as the problem is solved, I will not dig any deeper in this.

Thank you very much for your help!

Best regards,

Holger, living in Sweden

I'll attempt to build on and not repeat Gregory Pittman's suggestions. I wonder if the following could be the root of the issue:

- a font you're using is made that way -- have you used the relevant font elsewhere and noticed the same issue?

- you're seeing the effect of a ligature (combination of two or more
letters) rendering in a special way that looks wrong? For instance, some fonts have a grapheme for "ae" as "?" (see
https://en.wikipedia.org/wiki/%C3%86 for more information) which might be drawn differently from how "a" and "e" would look if they were joined together.

I concur with Gregory Pittman in that I too don't think the size of your PDF is the issue.

Perhaps you could post a one-page PDF extract from your document which demonstrates the problem? I'm guessing there is some place where we could all look at it and see the issue without needing to run code to get the PDF file, perhaps archive.org? Or perhaps this mailing list accepts small attachments?

This may have to do with how good the font hinting is with one font to another.
