How do I test to find if an image has a selection?
What I wish to do is: If image has selection, then do something.

I'm afraid that I find the descriptions in the Python console as clear as mud! Perhaps they are OK for someone who alreay knows the answer.

ofn-remove-grid removes table borders from scanned text. It is found here.

It was spawned from this discussion.

As always, comments, suggestions and bug reports welcome.

Enjoy.

In short, I scan a PDF document and then try to edit it as text.

My problem is that I can only do this using Microsoft Word, not with Libre Office Writer or OpenOffice Writer.

With LibreOffice the file opens but does not allow me to edit it.

With OpenOffice version 4.1.7 (currently the most current), editing is allowed, but the text appears encoded. I've tried several Character Set options, but a page with ascii codes always appears.

I didn't want to depend on having to use Word.

Does anyone know how to use either LibreOffice or OpenOffice to obtain the scanned PDF result in an editable text file?

I thank you for your help.

Hello,
I use GIMP 2.8.22 on Linux Mint 19. I discovered new software for OCR from a scanned pdf file: Scan2pdf and Tesseract. I would like to use OCR but the scanned pdf file is a table with borders, and some data are missing. It seems to me that we can remove / erase automatically with appropriate tools the borders (threesolds, contrast, light...) with Gimp. Please could you help doing this?
Cheers
Seb

Hi

I checked google and forum, couldn't find thread about this

To the point - i'm looking for way do downgrade quality od image in Gimp. I always did this while exporting file, but now in newest version i can't find window responsible for this.

this is maddening. i can't get any help elsewhere so hopefully someone here can get me out of this hell.

did a fresh install and still doesn't work. see video. i've tried Google but either my Google-fu is failing me or there's some idiotic thing i'm overlooking that no one else has because zero people seem to have this problem.

all i'm trying to do is get three dialogs on the right (layers on top, colors in the middle, tool options on the bottom) and a single column of the tools on the left. but no matter where i try to drop any dialog, at any time, it fails. again, see video.

i'm going out of my mind. any help is appreciated.

Afternoon,

Newbie here, what do the clamp input/ output tick boxes do in levels? I cannot see a difference on a 16 bit raw to tiff image that I play around with from time to time, ticking and unticking the input checkbox and looking at the preview histogram.

https://docs.gimp.org/2.10/en/gimp-tool-levels.html has no information and 

clamp input has the mouseover text "Clamp input values before applying output mapping" and Clamp output has "Clamp final output  values", both message seem to suggest that I am missing some critical piece of knowledge. I am aware the histogram is a representation on the tones or colours in an image and that levels alter the relative values on a mathematical way to alter the proportion of said tones to the human eye (as the computer does not care if big chunks and posterised splits appear in the histogram), but what is being clamped to what?

I want to use images like this, the black and white images, as alphas for ZBrush. I can't find out how to make them. Can you make them in GIMP? https://www.textures.com/download/3dbrush0089/127532

I have an image, in which parts have a green value of ~70, but I need to make it around 220. How can I multiply the green value in all the pixels on my image by 3?

I cannot tell exactly what I want to learn but I feel like I just do not know everything. I feel frustrated
when following steps for a specified purpose. As a result, I think I should at least get used to something
basic first.

Is there any recommended text and image tutorials for learning GIMP basics? Like lesson 1 lesson 2 ...
or week 1 week 2....

I do not like to learn through video or youtube because I am not patient enough to watch videos.
