Re: How to number lines in scanned text?

Adding line numbers to scans of a document is unlikely to be a problem encountered by forum members, no reason not to ask though, but have you searched online for something like 'add line numbers to pages of pdf document' ? A quick search shows this is evidently a need others have had, and it may be...

Re: tiff alpha/transparency channel - utility to scan files for its presence?

Glad you have found a solution that suits you, but I wonder if there mightn't have been a more direct overall solution avoiding the need to test whether or not a given file had an alpha channel. I started computing with Windows 3.11, and with a couple of very trivial exceptions never used DOS, and c...

Re: tiff alpha/transparency channel - utility to scan files for its presence?

There is more to this than is initially apparent as the TIFF format itself doesn't support alpha, neither the word 'alpha' nor 'transparency' appear in Wikipedia's comprehensive description of the official format: Wikipedia - TIFF However, this link does refer to a multlayer version of the TIFF form...

Re: tiff alpha/transparency channel - util to scan files for its presence?

I have very little experience with transparency but a quick online search has produced these two linked command line methods of detecting, and if required possibly removing, an alpha channel in an image: Detect Alpha Channel with ImageMagick Imagemagick: remove alpha component (replace all intermedi...

Neartly two years late, but just to bring this thread to a conclusion, I ultimately donated nearly all of the 78s to Internet Archive, so that eliminated the need for label scanning.
Thanks for reporting back! :D

Re: abbyy 12 - how to clean up and center pages after split?

I have Abbyy FineReader Pro 12 although I don't use it much now, and in the absence of any replies since BruceG's above I have fired up my Windows computer and taken a look at the tools available. When I view scanned book pages on the screen, I like the text on successive pages to remain centered on...

Re: How to save scans capable of being interrogated.

I'm not highly technical in that I know how to scan a document but all I finish up with is a picture and I have no idea how to set up the following. The scanner is an Epson GT 15000 and I use Windows 10 64 bit. I would like to scan a large number of documents and save them in a way that allows me t...

Re: ABBYY for compression?

I think that file size comparisons in relation to different workflows would need to be interpreted carefully, given the large number of variables, particularly in relation to compression options but also potentially in relation to source image colour mode and file formats. Given the quality of Abbyy...

Re: Edge cleaning?

I have been seeking something (Linux command line batch style) that cleans the edges of .jpg scans. Something that just replaces a few millimeters on the left and right with white. I am sure this can be done with imagemagick somehow, I just haven't figured it out yet. The imagemagick forum is proba...
