Is there a way to create a box that is 90x110mm, place it on the desired subject on an image, then scale the image so the subject fits the desired box and then crop the image?

Because first cropping without knowing if you hit the desired measurements, then scaling without knowing if you scaled too much or too little beforehand. Seems to me to be a long and cumbersome way of doing it.

FYI, i have 0 experience with gimp.

Hello.
This is my first message on this forum.
I'm looking for an answer which could improve my workflow in Gimp (2.10)

I'm making a story consisting of 580x410 PNG or GIF pictures and some text below the picture.
I'm drawing on paper, scanning, and then making the individual pictures in GIMP.

When making new pictures my workflow always starts the same way:
First step is adjusting the colour levels. (colors -> levels).
Next step is converting to an indexed colour palette (image -> mode -> indexed).
I select one of some palettes I prepared earlier, most have 4 colours. Sometimes I use dithering.

This is less straightforward than it could be because of lack of preview.
The color level adjustment step does have a preview, good.
The palette and dithering choice doesn't have a preview.
What I would really like is a single preview for a combined operation of both steps.
In a single window I would choose both colour levels and palette settings and see a preview of the total result.

Because right now it is like this:
I choose levels which I thing will be good,
then I convert to the indexed palette,
then I see that it does not look as good as I thought.
So I have to revert,
adjust levels again,
convert to indexed palette again,
and see if it looks better now.
I repeat this multiple times until I get a result which looks good enough.
This takes some time.

If I had the option to do it in a single step with preview it would improve my work a lot.

Is it possible to achieve this in GIMP?
How can I achieve in in GIMP?
If not in GIMP, then is there an alternative software where I can go this and then do rest of the work in GIMP?

hello dear friends 


in my gimp-writhings i have way too much distance in the lines ... can we narrow this down a bit?

Hi everyone,

Does anyone know of a way to import text from a text file (a .csv file, for example) into a text box?

Testing my near-ready cylinder flattening script on some random bottles. Either there is a bug or the yellow rim has a varying thickness to visually compensate for the cylinder "compression". But then the medals aren't completely circular either. That bottle has been emptied and I didn't keep it so I'll have to fetch the other one tomorrow and take some measurements.

   

Still working on my greetings cards...on a file I've created which is 8in x 6in, I'm making a 4 x 6 card and attempting to copy what a lady did in a video, she was using Lightroom. She made a rectangle selection the size of the front side (4 × 6 in my case) then opened the image she wanted there, and aligned the image to the selection to get it centered (so far so good, and the best way I've found of centering the image so far) but then she GROUPS the image with the selection, and moves it into place to the right hand side of the file. I CANNOT for the life of me find a way of grouping them together in gimp. No matter what I search for i can't find a tutorial. 

Does this even make sence? 

It does work, but I find I have to:
- hunt for the dialogue box centre screen but behind the main GIMP window.
- move it to a position beside the main GIMP window 
- click on the target image in the main window
- double click on OK in the border dialogue box
- sometimes repeat the last two steps once or twice more before anything happens
I am using Mac OS-X Ventura and GIMP 2.10.

I am completely at the starting block wrt scripting, but if anyone is in a position to correct this behaviour for a future update, please could they also consider adding:
- tool preserves current settings (width, colour) for next use
- dialogue box opens where you last left it, and floating above (overlaying) main GIMP window.

Hey all, this is my first post here, although I have used Gimp for a long time for simple things.

I have problem that I think Gimp could help me solved, but I'm not sure how. I have an old service manual scanned, in a very good shape in general, but would be great if I can bring it to almost perfection. I think there are three things that could improve the current quality from an 80% to a 95% (subjective numbers). These things are:

• Remove all single pixel marks. The document has in the background some single pixels (over the white background). Removing al those would be a large improvement.
  
• Straighten out the pages. Some pages are not perfectly "vertical", so detecting the pages that are at an angle and rotating them would also be a huge improvement.
  
• Use OCR to read the text and replace the some how "broken" characters with newly rendered ones of the same font and size.
  

• PDF to individual images
  
• Process each image
  
• List of images to PDF

Hi,

I was playing around with my settings, as I always want JPG's to export at 100% quality (it always seems to want to downgrade to 90%?). Anyway - now when I export an image as a .jpg I get a corrupted image. Here is my settings:

(sorry, I don't seem to be able to embed images via , and the upload attachment doesn't seem to work?)

Anyhow - if I look at the generated .jpg file in Notepad++, I can see it has the right start:

ÿØÿà JFIF

So I'm unsure whats going on :/ When I try and open it in Photos I get:

Any suggestions? I've tried to do a "reset" of the settings but that doesn't seem to help :/

UPDATE: I just installed 2.99.14 beta, and it showed:

Quote:gimp-user-install: migrating from C:\Users\Andy\AppData\Roaming\GIMP\2.10
Gimp-Config-Message: 15:24:31.556: Error while parsing 'C:\Users\Andy\AppData\Roaming\GIMP\2.99\gimprc' in line 14: invalid value 'convert' for token color-profile-policy

This is a development version of GIMP.  Debug messages may appear here.

Do not know if it is a script or plugin. Can someone attach this here please or link me to where I may find it?
