Converting Screen Shots

Hi list,
I'm a newbie and have the following problem: I have about 2500 screen shots in png-format. I need to convert them all into b/w-pictures. How could this be done easily? Furthermore (but I guess that will be the issue in another list), I will have to run all these screenshots through an OCR-program. So what would be the best output-format for these screen shots? (And yes: If someone has an idea how I could run these screenshots through an OCR-program, I'd be very happy....)

Cheers

Paul

Use imagemagick's "mogrify" program on a cpoy of the images.

The best OCR package still seems to be Abby FineReader, which is commercial but about a gazillion times better than any of the Free/Libre ones I've tried.

You tell it to Read Images, select the first image, shift-click on the last image to select them all, and go for a short walk (barefoot, of course).

Abby can handle colour PNG files just fine.

If you are using some other OCR program you'll need to tell us what it is before we can suggest anything in more detail.

Note that text on screens often has resolution too low to get good results with OCR. What is the text??

Thanks for the hint. Just read the tutorial and it seems as if this is perfect.

I'll give Abby FineReader a try. The screenshots show some text which is blurry, but hopefully, the result will be better than everything I've got until now. At the end, a script will sort all output in a cvs-file... if the OCR does what I hope it will :-)

Thanks again!
