Hey all,
I'm looking for a way to project a picture onto a cylinder like here: http://gimpforums.com/thread-project-ima...tary-curve
- progressively shorten one axis while leaving the other axis unchanged. I get the idea of the displacement map, but I can't get the gradient right - I don't really get ofnut's formula, nor how to implement it into a gradient...
Thanks in advance,
Akir

This came up in another section.
Three images divided up into equal(-ish) sections. A useful topic as it introduces some of the basic Gimp tools and editing aids.

   

Guides and Grids: https://docs.gimp.org/en/gimp-concepts-i...uides.html
Layer masks: https://docs.gimp.org/en/gimp-dialogs-st...layer-mask
Selection tools: https://docs.gimp.org/en/gimp-tools-selection.html

A bit of composition in the layer dialogue...and of course, it has all been done before in the documents https://docs.gimp.org/en/gimp-image-combining.html

For better or worse my take on the subject 5 minutes duration

Hi,

When I want to close GIMP and click the cross-box in the main screen it closes only partially, since the tool boxes left and right of the screen stay open and tell me that GIMP doesn't respond. Clicking them separately wil finally close them.

Any suggestions?

Kindest regards, Leo.

How do I create a gradient map from an image?

If I have an image that I know started off as greyscale and that somebody has colourized it with a gradient map, and that the resultant image is sufficiently detailed to have all 256 lightness values mapped to a colour -- then how do I create a colour gradient map from that image so that I can colourize images similarly myself?

I know that this is possible because I did it myself a few years back and I have the .ggr gradient maps that resulted, but Google has failed me now and I've forgotten how I did it.

Hello,


do you know if it is possible to script funciton:

colors - desaturate - color to grey?

I didn t find it

as well as: colors- Color temerature


Thanks for your help

        I need to remove the lines from the following image. It was recommended that I use threshold. When I tried that, it removed some of them, but not all of them. In addition, it turned it black and white. Is there anything else that can be done?

Hi everyone. I downloaded GIMP a week ago. I want to make a thumbnail for my YouTube video, where 3 pictures of 1920*1080 resolution are put in three equal parts in a 1920*1080 picture. I want them to be divided by three slashes (/) rather than a straight line. Thanks!

Hey all, I'm having a bit of trouble here.  A few days ago, Windows 10 decided to do an automatic update, and ever since then Gimp crashes on startup, specifically when updating the tag cache. 

Here's the exact error message.



Currently I'm using gimp 2.8.22, however when the problem first started happening I was using a slightly older version.  I had uninstalled and reinstalled gimp several times, attempting to solve the problem.  

I don't have any brushes or plugins installed, and I only had one font installed, although I probably don't anymore, since I had deleted every file on my computer with the name Gimp attached to it.

This problem is frustrating to say the least, and I'd greatly appreciate any help.  Thanks!

Can someone to explain how to use with the plugin?
