I have an image with an aspect ratio of 0.62:1 and I want to change it to 0.71:1 and live with the distortion: the image includes text so it can't be cropped.   

As a new user, I have spent what seems like hours Googling "changing aspect ratio with Gimp" and trying without success the few answers I found.  

Can anyone please walk me through a method or point me to a tutorial?  I use Windows 10 and Gimp 2.10.20.

I have a picture of a sheet of music which came from a colour photograph .jpg and then was converted to grayscale in Gimp.

That hasn't make it black and white but instead gives me an overall grey cast on my HP black and white printer.

I tried setting it for indexed colour on black and white and that was terrible.

I have a whole heap of these to do and it would be good if I could find a quick simple way.

A few years ago I used to use Paintshop pro and if I remember right I had a kinda two keystroke fix for this - I think I just set it for a low color depth or something.

There's be something in Gimp I imagine?

I'll attach the particular one I mean today.

I recently saw a video for Photoshop users on how to make photos look like an oil painting. Is it possible to do something like that using GIMP. Or is it better to use Krita ? I know both GIMP and Krita are awesome tools for painting. But I see that some people favour Krita more than GIMP when it comes to painting like projects. My Krita knowledge is very minimal and I have used it like 5 times in my life. And support is pathetic when I tried for Krita. I wonder whether there is a forum like this for asking doubts. Personally, if there is any good video I can rely on I will stick with GIMP and try to convert a couple of pics I have. Any help will be awesome.

New Image.

Right click image, colours > Components > Decompose

RGB > Ok.

Add layermask to each layer (Shift click)

Pencil in white on the layermasks to what is wanted

Right click image, colours > Components > Recompose

The image does not take the layermasks.


This is also the case when right clicking the layer and 'Apply layer mask' the recompose

Thanks

I am trying to modify a channel using gimp_drawable_curves_spline. The line I am using is:

pdb.gimp_drawable_curves_spline(image,HISTOGRAM_VALUE,18,0.0,0.0,0.0625,0.125,0.125,0.250,0.250,0.375,0.5,0.5,0.75,0.625,0.875,0.750,0.9375,0.875,1.0,1.0)

It gives me an error of wrong number of parameters. Obviously something silly on my part, but I have checked my decimal points, counted my commas numerous times and still can't see what I am doing wrong!

Any help much appreciated.

Hallo,

I'm trying to set the mousewheel to zoom the image. In the window: configure input controller, main mouse wheel I added at the event ScrollUp and ScrollDown the actions: view-zoom-in and view-zoom-out.

Zooming is still not functioning. Also with ScrollUp(Ctrl) and ScrollDown(Ctrl) it doesn't function.

May be it depends on the Manjaro release? (Window Manager Tweaks?)

Can somebody help?

Manjaro XFCE 20.1, GIMP 2.10.20 (from repository)

Many Thanks.

Godday,
if you have two images of the same object (let's say scans, to evade some of the complexities of photography), where
image A has captured the colors correctly, but is otherwise undesirable (blurry, low-resolved or the likes) and
image B is adequate in detail but lacks color (greyscale).

Question:
Can i use image A to paint image B without degrading the latter,
and what is this task called in terms of digital imaging?

Hi all

I have lost the left hand menu of Gimp with all the tools listed. Does anyone know how I can get it back?

Hopefully some kind soul can solve my problem.

Hi,

What change can I make to make the script functional again?

Script: RMA_label_points.scm
Gimp: Samj's portable 2.10.21 / win10

Thank you very much in advance!

How would that work?

• I assume we can't avoid specifying an angle and a spacing.
  
• Should the script do the path rendering (and so take a thickness as a parameter, and may be some "dot ratio"), 
  
• Should the path be kept
  
• Or two options above combined in render and discard path/don't render and path (as written, calling the script  on the same layer with the same specs will always produce the same lines, so successive hatchings in different areas will remain aligned
  
• Should the script be able to separate odd/even lines
  
• Ini file for defaults?
  
• Ini files for several defaults?
  

• Creates path lines with spacing and angle that cover the active drawable.
  
• Rendering is manual (and so abides to any existing selection)
