1 bit TIFF OCR issues

[dixus]

Hello,

we have problems with multipage TIFFs that we get from our customer. I tried the GDPicture OCR feature.

As you know, 1 bit TIFFs are difficult ( windows image view shows pages inverted)...


The problem is that it looks like the pages that are shown inverted in image viewers arent recognized by the GD OCR engine.


Is there a setting that checks and corrects that ? Or do the TIFF need to be 2 and more color bits?

Hi dix,

There is no know issue of reverted image in GdPicture. I suspect your image to be invalid.

If you want investigation do following:

- Attach your file or send it to esupport (at) gdpicture (dot) com
- Give us the name of the toolkit you are using
- Give us your OS version
- Give us your toolkit version

With best regards,

Loïc

looks like i could solve the problem by converting the cloned tiff to grayscale image before running the OCR...
