PLEASE NOTE: Within an hour or two of posting (below) I discovered the answer on my own. Everything I had read referred to Control-clicking. I should have known to try Command-clicking on Mac. D'oh!. That's the answer.

Brand new to GIMP and struggling.

Running GIMP 2.10.38
Mac OS X 11.7.10

I've been using computers for a long time. Thinking about moving from my current mid-2015 MacBook Pro to a new M4 MacBook Pro. If I do that I will lose the ability to use my old standalone (non-subscription) version of PhotoShop CS6 so I'm looking at GIMP as a possible replacement and trying to see if I will be able to do what I want.

One of the things I can do in PhotoShop is to look at the RGB values of a point in an image while at the same time seeing what the values are as I change curves. levels, etc. This has been very valuable to me as I color correct and I've been trying to replicate or approximate this functionality in GIMP, and basically getting nowhere.

This brings me to creating sample points. This was the first step in the process in PhotoShop. It was simple: click the tool and then click the image and bingo, you had a sample point on the image and you could a number of them.

So far I have been unable to create a single sample point in GIMP. I have a copy of the  GNU Image Manipulation Program User Manual November 17, 2021 which says "To create a sample point, Ctrl-click on one of the two measure rules of the image window and drag the mouse pointer. Two perpendicular guides appear. The sample point is where both guides intersect. You can see its coordinates in the lower left corner and the information bar of the image window. Release the mouse button." This doesn't work for me. If I control-click on the upper (horizontal ruler) and drag it puts a horizontal line on the image. There is no perpendicular guide. In order to create a perpendicular guide, or line, or whatever it is, I have to control-click on the vertical ruler. I don't think doing these things creates a sample point where the lines intersect or anywhere else for that matter as no sample points or shown in the Sample Points dialog.

Queries of AI bots Gemini and Copilot yield varying and differing instructions on creating sample points. Some of the instructions are impossible to follow and those that an be followed simple don't seem to work.

I'm not off to a good start with GIMP. Can you help? What am I missing?

Thanks.

Hello,
When I use a map on a cylinder object, the image stretches or expands (even though I didn't scale it). How can I avoid this?

Additionally, I adjusted the layer to match the image size so the entire image would be visible.(Layer-> layer to image size)

Hi there,

I am working on the following image.

I am trying to make a water splash effect around the tiger. To do this I am using the turbulent water image that is also attached. What I have done is I have used the clone tool using a water splash brush on the turbulent water image, and then brushed around the tiger to create the water splash effect. But it doesn't look that realistic. It's better than when I first started but it doesn't go with the image. Hence, I am wondering if someone could help me make this splash effect look realistic?

Many thanks in advance.

PS: I can't upload the xcf because it says the file is too large. So, I am not sure what I can do.

this image seems to me to have more punch than the original photo; the height and width of voltage are clearly visible  !

Does anyone know if Krita has a feature akin to GIMP's float selection, or should that be selection float... 
Anyway you know what I mean  
Even if there is, as I'm using Krita on my Android phone, it might be the case that I cannot use it anyway as this version of Krita is optimized for tablets.

gimp-plugin-registry is not updated and not works, G'MIC is old release.

Only gimp-data-extras works, but are brushes, patterns and gradients.

Let's give Debian time... Debian 13 isn't even scheduled for release.

Hello,
I tried applying an image using the "Map to Object" tool with a cylinder, but I encountered two issues:
1- Border Shape: Can I change the shape of the border? For instance, if the arc of the upper border curves upwards, how can I make it curve downwards without using the curve bend tool?
   
2-Image Scaling: When I scale the image larger than the mug using only the "Map to Object" tool, it ends up sitting above the mug instead of curving inward as intended.
           
I want the result to look like this example:
     
Here's the original image for reference:
   

I found this some time ago and just re-found it
It's a GitHub project that 'provides a simplified interface to call procedures and plug-ins from the GIMP procedural database (PDB) - the same style used in Python plug-ins for GIMP 2.10 and lower:

Ofnuts could be interested in the way this works.

Hello All,

I'm a fairly new user of GIMP, running v2.10.38 on Windows 10 64-bit. I'm trying to solve an export probllem that might be related to the following behavior:

I import a multipage PDF and each page appears as a layer. In the main editing window the last page of the PDF is displayed. Even if I select another layer (page) in the Layers Dock, the last page is still displayed. The only way to display anything other than the last  page is to start turning layers off. If it's a 5-page PDF, I make layer 5 invisible and layer 4 (page 4) is displayed. Again, selecting layers 3 or 2 or 1 doesn't change the main window display, it stays at layer 4 (page 4).

I searched the forum, didn't find anything. I skimmed through the online manual 16 - 7 The "Layers" Menu and didn't see anything relevant. I looked through Edit > Preferences and didn't see anything relevant.

I'd think that logically the selected layer (page) would be displayed in the main window, but it's not. Is this normal behavior for GIMP? If it's not, any ideas for fixing it?

Ever since the  win 11 24h2 update gimp 2.10.38 freezes the computer after I use the Foreground Select. I can make the selection and do Enter but when I click Select on the FG popup the computer freezes. The few times it hasn't frozen when I click Select it actually unselects.
Is it the update or what else could be going on?
