I have been updating my website_photos1.py plug-in to make it more useful and also as part of my learning exercise.

Is it possible to validate that "Sub Directory" and "New Name" have been entered and if not return the user to the entry screen?
I have been searching for several days to find an example of code to do this, without success.

An additional query: How to put additional lines of text or separators in the UI of a plug-in in order to make it more readable or give explanation.

Running GIMP 2.10.38
I am having trouble using select tools, I suspect because I have done something wrong but I don't know what!

I have attached a screenshot of what I see at startup.  If I hover my mouse over, e.g. Ellipse Select Tool, I see the dropdown list with Also in Group, however I cannot click on any as the dropdown disappears as soon as I mover the mouse.  Also if I choose a select tool I do not see the options that I see in video instructions.

I have gone to Edit > Preferences > Tool Options > Reset to Default Values, restart, but it made no difference.

What am I doing wrong???

Thanks
Mick

Sorry, but could you please tell me?

I want to create a palette called blue using the colors used in an image and then change to indexed color mode based on that palette information, but I'm having trouble.

For example, if there are two colors in a custom palette,

Color A (R100 G100 B100) and Color B (R100 G100 B101),

the color will be automatically converted to one of them.

The following settings should also be fine.

- No dithering
- Uncheck Dither transparent areas

Is there a way to convert the color information in the custom palette without tampering with it?

Hello,

I am new and read some nice posts here so I thought maybe give it a try and ask. For my brother's business I created a logo. I used the vistaprint template to make a business card. Since the card itself should be black, I used a black background layer that I toggled invisible when I exported the png for printing. I created kind of a mirror effect by duplicating the logo layer and making it half transparent, and a soft glow around one element of the logo using gaussian blur. These two effects totally get lost when I do not export the png without the black background layer. The half transparent mirror layer is almost invisible without it, same with the halo effect. I tried checking all the options for export so nothing gets lost but it did not help.
I could just export with the black layer but this will be a problem when we make his work shirts. Does someone know what's going on there and help me please?

Kind regards,
Nio

Hello,

When I map an object as a cylinder and adjust the radius to fit the base image (e.g., a mug), the image stretches. How can I avoid this?
Even if I scale it it will stretch

Not meant for Gimp, but blend modes are common across image editors. Some math insides, but nothing too hard, and nice examples.








 Enjoy.

I would like to give those who are interested an example of different productions from the same image merged with a pleating base (already seen, but with slight modifications which multiplies the possibilities). The initial image is a transformation of a photo of a rose that I called "Imaginary Lagoon". 
In a post I cannot give all the details of the process, but I will be able to answer a few questions, if anyone wishes.

First, the Imaginary Lagoon 
   

Then:
1. merged in LCH color
   

2. merged in HSV saturation green
   

3. merged in HSV saturation blue
   

4. merged in soft light with green modified
   

5. merged in grain merge, finally the least sucessful in my opinion
   


I don't know if this post will interest anyone, but I'll see you soon

Hello, I’ve been learning GIMP for two weeks and now I’m stuck in one place, and that’s that I need to wrap the text around a circle, in GIMP, it never becomes a complete circle

(The blue line is my path, and the red line is the path around the text)

Strangely, no matter how I adjust the size of the text, it still doesn’t work
It seems that it can only reach a semicircle

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)
