PDF OCR output

agua102 · 07-07-2014, 03:18 PM

Im using Abbyy Finereader 12 with a pdf typically 80 MB.
In the context menu appears make PDF searchable. The program make a pdf searchable of around 8 Mb. The result in a mac with a cpu i7 is cpu charge 100% anytime i turn the page. What I m doing wrong. I use PDF or pdf-a with same results.

Is there a sticky post with how to make ocr?.

Obviously the pdf in android or ipad is very slow.
I only want, at least to read in the mac. The pdf file without ocr only has 20% of cpu use.

Thank you.

I haven't tried out Abbyy Finereader 12 as yet, but I have noticed that quicker ocr-ing and better compression (smaller files) of Abbyy 11 usually means somewhat slower pdf rendering than for Abbyy 10's files (on e-book readers and tablets), so I usually use Adobe Acrobat's 11 ClearScan mode.

Maybe you could simultaneously use both pdfs, un-ocred and ocred (pure text rather than ocred pdf image), as you would use additional dictionaries, audio players etc. while reading.

Un-ocred for quicker reading (and handwriting without highlighting) another one for searching and word definitions.

CPU charge is not nearly as important as whether the program is running slowly or not.

CPU charge of 100% simply means your computer isn't wasting cycles on idling.

Are you suffering any slowdowns?

Yes ... I think the problem it´s in OSX libraries or similar. Preview, Adobe readerX, Skim all cpu 100%. In Adobe reader in windows thought parallels it´s 15% cpu the same pdf.

I was searching through the apple forum comunities but any answer yet.

Note: In all version of OSX i see always "Preview" very buggy ... and its the core of the osx I think.

If AFR got the size down from 80 MB to 8 MB then the compression must be dialed up pretty high, which, like Markom said, can slow down rendering and make it CPU intensive. Is there an adjustable setting for compression in AFR?

Depending on the input, it could also be going from Color -> Black and White saving you a massive amount of space.

Or the when the input PDF was created, it was just uncompressed or lightly compressed.

Nope, not that I am aware of.

You can see a quick capture in osx.
%CPU is 225% , Idle wake ups 56 in "preview"

the lack between capture gives 96.5% ... but it was 225%
