capture sequence

Hi Gents,
Is there any way to capture a sequence of Studio transforms, so they can be replayed as a macro?
Thanks
Rick

Re: help with coding Mogrify

Aha. The Blur parameters. In the command line, the blur radius of 0x20 is not hexadecimal 20. What it really means is radius=0, sigma=20. For the same effect, does the perlmagick need to do this? $q->Blur( radius=>0.0, sigma=>20.0); Now the results of the Perlmagick are the same as for the command l...

Re: help with coding Mogrify

In the original post (above) you will see a convert command line, which works well for me. I would like to translate that to PerlMagick, but no luck yet!

Another post discusses my goals: viewtopic.php?f=22&t=26190
Thanks

Re: help with coding Mogrify

Thanks for helping. Now we have this: $image->Quantize(colorspace=>'gray'); my $q = $image->Clone(); $q->Blur( radius=>16); $x = $image->Composite ( compose=>'Divide_Src', image=>$q ); if ("$x") { print LOGFILE "image modu = $x \n"; } The resulting image is all white. There is no mention of compose=...

Re: OCR of typewriter copy

Oops, sorry, hold that last post. The -lat method gives more words in the OCR output, but there are incorrect and broken up words. The -divide method gives almost correct text. I should try other values for 15x15.

Re: OCR of typewriter copy

Thanks, the -lat command line gives better results than the -divide line. Both work better than the old way, where I just brightened the input by 50%. I have not tried the textcleanup line yet but would like to.

But now I am using more CPU time for 'convert' than for 'tesseract. Yikes!

What I have so far is shakey: my...

OCR of typewriter copy

This is my first post here, so hi everyone. I have been using Imagemagick to pre-process images in preparation for OCR. But the input is typewriter copy which is a problem because some characters are typed with less force and so are considerably lighter than others. The other problem is that the whi...
