Hello all, new here, and fairly new to Gimp.

Without overly complicating it, here what I am trying to achieve.

The image below is something I am trying to replicate. I'm going to create a wind dial for Rainmeter. However, there are two things I'm having trouble with, and hoping maybe you all can help me out.

As you can see the image is broken down into some type of gradient. How would I go about implementing that sort of gradient in my own circle? I am not using any actual part of the original image, so I am using it's size as a guide. Is there some way to divide a circle into 24 equal parts and bucket fill each one?

And here's the second one, that I think I already know an answer to, but as you can see below, the circle also doesn't have full opacity, meaning, the color values you see aren't what they would look like against my wallpaper, which is basically a replication of the "grid" background. Thus my question is, is there some kind of "smart" way to determine the color values shown below but what they would look like either with the black background removed OR if they were 100% opaque?

The end goal is to create an asset of higher resolution and quality, but with accurate color values and opacity reproduced by hand.  

Hope I explained correctly.

Planning to install Linux on my 2003 Dell XP PC. Wondering which distro is preferred? 
l have played with Linux Redhat years ago but need to relearn. 
Thanks Carl

When I load a file and want to reduce the size, whether I scale the image or scale the layer, I still end up with reduced image and large boundary. ( I guess that's what that is)
See the attached screen shot.
When I use view: fit image in window, it still sees the transparency.
I'd like to get rid of the large transparency and just be left with the picture (reduced in scale)

I need to do the following to all open tif images in Gimp.

change mode from indexed color to grayscale
scale image to half size (from 9912x7008 to 4956x3504 and resolution from 600 pixels per inch to 300)
save to xcf format using current file name plus a -300 suffix

I have a couple hundred files in 25 folders to do. Doing one at a time is slow going. Any way to speed up the process?

Thanks Fred

The zoom function has several preset % which are nice, but I often would like a percent not listed.  Is there any way that I can make a 75%  or 80% that stays permanently.  I can add it for an image temporarily but it seems to disappear.

Hi everyone I am new here. I use a mac all up to date. I run a Train simulator. And want to reskin some of the locomotives. I can manipulate the template of the locomotive ok, but my problem is when I am done I can't get rid of the last Rectangle Select tool dashed outline. And when I save my work and reopen it's still there. Flusteratring. Thank funnnyfarm

This is a follow up from a request for a Gimp plugin "A Stencil" that creates an 'edge' to constrain a paint tool.

Gimp does not have that tool and I think that using standard tools to create a selection is one way to go.

A short video demonstrating two possibilities,
1. Using a path to create a selection
2. Using the quickmask tool.





More about basic use of the selection tools here.

I am trying to completely remove the background from an image. I open the image, add an Alpha Channel, and then erase the background to all checkerboard. But when I export the image it still has a white background. Or what ever the color is selected for the background on the color selector.

Hi.
I'm using Gimp 2.8.20 running under Windows 10.
Absolute have fallen in love with the Gimp program and am so grateful to every one who works tirelessly an mainly thanklessly.
I would like to see Stencils available in the shape of straight ruler (adjustable length and width), circles, ellipses, and various french curves. these would be very useful when masking, erasing, painting, etc.
If there already exist such as these, kindly direct me to link.
Thanks in advance,
Ed Ingram
