Controlling The Gimp

monkeybus has asked for the wisdom of the Perl Monks concerning the following question:

I have scanned a few thousand images that I want to run through Tesseract to OCR the text contained within.

First though, I have to run the images through The Gimp to increase the colour threshold and convert the images to 1 bit indexed monochrome.

Is there a Perl module to take care of this?

Thank you kindly, monks.

It should be possible using modules like Gimp or Gimp::OO, but I have not used them myself and they seem very old. Have you considered using ImageMagic or Imager for this task? Just search the CPAN... Hope this helps	[reply]

Here's a good tutorial on using Perl with Gimp: A Tutorial For Perl Gimp Users Be sure to check out the plug-in registry as well. You can use the advanced search option, and select GIMP-Perl under type: GIMP Plug-in Registry ----mmmmtmmmm	[reply]

Easier to use imagemagick's `convert`	[reply]

Try, perlmagick if you want to use perl, it is an API to ImageMagick, `$img->Set(monochrome=>true)` [download]	[reply] [d/l]

You may be able to do this more quickly and efficiently with Imager.	[reply]
