  ofn-flatten-cylinder
Posted by: Ofnuts - 03-24-2023, 06:29 PM - Forum: Extending the GIMP - Replies (13)

Continuing with my obsession over cylinders in general and beverage bottles & cans in particular, may I introduce you to ofn-flatten-cylinder, that takes the image of a cylinder (or something on a cylinder):

   

And flattens it:

   

Of course,the pictures have to be taken carefully to be usable by the script, see the doc.

As usual the script is here.

Enjoy.

  Plugin for refreshing old photographs
Posted by: Whippie - 03-24-2023, 06:11 PM - Forum: General questions - Replies (7)

Hi all!

I'm new to Gimp. I want to make a photobook for my parents 80th birthday. I have some old photos, that are faded and strangely colored. I googled a bit and found a plugin (restore.py from https://github.com/stongey/PhotoRestorewritten in python) that was really old but with great results. I tried to install it, but with no luck. I finally installed Gimp newly with python and some other packages (took me some hours to try all the hints) but still that plugin does not appear in the menu. I'm using Ubuntu 20.04 with Gimp 2.10.34 and Python 2.7.

Are there any other plugins working like this one that are easier to install?

And if not, how can I refresh the old photographs? Are there any good tutorials / videos? And didn't find good one when searching. Maybe I didn't use the right terms for searching.

Many thanks in advance!

Silke

  Turn a pic in few shades of black and white
Posted by: rico - 03-23-2023, 02:16 PM - Forum: General questions - Replies (2)

Hello everyone
Does anyone know how to turn a photo into black and white but with very few intermediate shades?
I try to laser engrave a photo on wood and the problem is always the same: there are always too many variations of light which create a range of light too big and which results in the engraving either by white or black zones without no details.

whereas if I engrave a vector file, a logo, as there are only 2 shades, it works very well.

Would there be a way to homogenize the photos around only a few degrees of black or white?
Thank you in advance for any help you can give me.

  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?
