  Percentage scaling
Posted by: Zjho - 03-22-2023, 09:28 PM - Forum: General questions - Replies (6)

Hello forumers, newbie here, this is first post having joined today.
Help appreciated with anything that can be done about in my opinion poor state of percentage scaling defaults that suspect is a chronic bug (for GIMP 2.10. and below).
Have looked through tutes but found nothing relevent yet.
Have used GIMP for many years on various distros, both Debian and Redhat based and always found the method used to construct the set of percentages unhelpful and time wasting.
In an ideal world would like to be able to open a new image to fill the padding space perfectly in one of the dimensions and also keep a 100%.
However let's assume this is too arbitrary, but even so, there could still be some mechanism to stop there automatically appearing what i think of as useless values, let me explain.
There may be a config file that holds previous used percentage values, but for those of us using varying sizes reusing these serves as a distraction i would like to disable. Closing the package and reopening one image usually offers about eight %ages 12.5 through 800 plus one other, perhaps from a previous user selected value but often don't believe it is. Opening another single image while package still open can give up to about ten %ages, the three more are often unhelpful because although may be from previous use, again, don't seem to be. Many a time the surplus percentages to standard 12.5 through 800 are between 90 and 110 only, sometimes there being two at say 96.1 because in reality it must have a 96.15 and a 96.16 but the last digit is not shown, this is very time wasting to scroll past for those of us who use a mouse wheel. These values almost certainly were not used recently beforehand. If something outside 90 to 110 is selected it is soon lost in favour of the 90 to 110 range, already very close to 100 anyway.
My desktop hardware is not limited by RAM capacity or CPU speed.

  Cannot move a selection/layer
Posted by: kev_hobbit - 03-22-2023, 07:00 PM - Forum: General questions - Replies (4)

Hello, I tried searching for a solution but nothing I found has worked yet. Basically I am not able to move this image. I have the layer selected, and it is not locked. I press 'M' but I also try clicking the Move tool on the left-hand panel/window. However, it is not moving the image.

Here is a gif of the problem:

I would greatly appreciate any help!

  Restoring partially discolored photos
Posted by: rmiranda@inter.nl.net - 03-22-2023, 09:12 AM - Forum: General questions - Replies (6)

I am new to this forum.

Please look at the attached photo. It is a 40-year old photo of a river in Holland. I use Gimp regularly to restore old photos, but this one stumps me because:

1. The colors have faded
2. In addition to fading, there is discoloration (purple hue) in parts of the image that were probably exposed to sunlight.

This combination makes it particularly hard to restore.

The trick - I would guess - is to apply the color spectrum of the non-discolored areas to the discolored ones to generate a more uniformly colored photo. After that, one can do fine adjustments on the whole image.

Has anyone had experience fixing this kind of problem? What is the best approach?

  Crop & resize image to measurements.
Posted by: idiocracy - 03-22-2023, 08:08 AM - Forum: General questions - Replies (17)

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.

  Combine color levels with indexed conversion with single preview
Posted by: bicyclesonthemoon - 03-20-2023, 02:41 PM - Forum: General questions - Replies (5)

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?

  Newcastle Brown getting on my nerves
Posted by: Ofnuts - 03-20-2023, 01:11 AM - Forum: Watercooler - Replies (3)

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.

   

Btw, a bit disappointed by the taste. It was better in my memories. Also, label on back mentions sugar... They no longer do good beer up there?

  Group image and rectangle selection
Posted by: Rakelle - 03-19-2023, 03:34 PM - Forum: General questions - Replies (2)

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?  Blush
