OCR on PDF

[nskd]

Have been developing a OCR function on a PDF document. Things are running perfect on PC#1. But when the script is ran on PC#2, the OCR will go haywire as it is not detecting the desired X,Y coordinates. I believed PC#1 and #2 screen size being different and is causing OCR not to performing as what I had programmed.

Is there any way to perform some kind of standardization, so whenever this script is deploy on PC with different screen size, the OCR will always work?

Make sure you are taking DPI into consideration.

Hi Grovkillen,

That’s for replying. I am not very sure the DPI thing that you mention. Are you able to elaborate on more on that or maybe direct me to any online references.

Thanks again.

If you look for the screen DPI (it's been mentioned in other threads) you see that these can differ and it'll make the OCR miss it's target.

Looks like this is a limitation for all OCR programs, am I right?

[Grovkillen]

Yes that would probably be true.
