I'm not currently a Gimp user, but I'd like to know the equations used for the vignette filter. Are they anywhere in the documentation, or just buried in the source code somewhere?

As title says.

Can't get a "filled" text (tried with Fixed and Dynamic box sizes), the "Filled" icon does the same thing as left-justified. I would report a bug but I want to make sure I'm not missing something obvious.

Please God, have mercy on me. My intentions are good. This is to make a gift for a precious friend, a game set.

I am trying to reproduce the rings shown on the game board in the image at the bottom of this post.

Since there aren't any "how to draw a colored ring" directions, I am attempting to follow the steps on WikiHow entitled Draw A Circle in Gimp.

https://www.wikihow.com/Draw-a-Circle-in-Gimp

However, even though this guide is insanely long and arduous, it is missing crucial information.

It does have pictures, but not ENOUGH pictures.  It names things, but does not tell the user WHERE in the insanely complex GIMP interface, to Find Them.

For example, Step 6 says 

"Select the color you want to use for the border in the color picker. Click the current foreground color in the Toolbox and select the color you want to use as the border for the circle."

This is Not Enough Information. The image on step six shows a rainbow menu.  But going to Tools > Color Picker does NOT show me any such rainbow menu.

Thank you for your constructive advice.

I have pasted an image into GIMP and now would like to superimpose a TEMPORARY grid of lines
to assist me in positioning shapes over that image.

It isn't clear how to do this.

       

Ok, I'm trying to do a simple project, not get
a college degree in how to use GIMP.

I have ZERO knowledge of computers or
software.

After this, I might never use GIMP again.

If this forum allows it, I will upload the image
in question.

What I am making is an image that I will then
pay Office Depot to print out as a poster.
I will then cut it up and construct a game board to give as a gift.

This link below shows what I want the finished game board to look like.

So, I began by hunting on google for a nice crisp image of the texture and shade of the background, sort of a woodgrain.
I could not find what I really wanted, and settled on an image of corkboard.

I pasted this into GIMP.  The board has got to
be 16 inches by 16 inches total.  

I begin by changing the ruler in GIMP to inches, and it shows that my pasted image is too small.

This is where I'm running into trouble.
I have "re scaled" it, but then two things become problems.

Number one, the ruler stays exactly the same.
This is confusing, so please be patient with me. What I mean is that the ruler does not fit the enlarged image.  Even though the image is larger, the ruler isn't changing.

Another problem is that now the cork board image I got off Google is so blurry that it looks awful, it is worthless.

After I get the background, I have to understand how to draw the colored rings and circles and lines and dots and the corner decorations.  I will probably have to find some clipart for the corners, and have to learn how to insert that clipart.

Kind of desperate here.  I have only a month to finish this birthday gift.

I hope you can see my screen shot.  The ruler says the image is only a tiny bit more than 4 inches by 4 inches.
The Scale dialog box says that it is 40 inches by 22 and a half inches!

I mean...does it HAVE to be hard, confusing, frustrating, punishing? It can't be intuitive, friendly, easy, nice, useful, pleasant?

Hi, I'm working hard to traslate the many tutorials I wrote for my italian website in english and update the one I've already wrote to the new version of Gimp.
This is the newest one I fixed, and I really think it could be useful for the community.

I really hope you will appreciate, if you like it, I'll keep you updated with the new tutorials I'll write in the future. Best things.

I have used GIMP for years and saved my art as jpg's and then succesfully uploaded them to Canva for printing.  I got a new laptop and installed the new GIMP and now when i export as a jpg it works, but when i export it to Canva the files say "We are unable to upload this file as it is incompatible with Canva or it has been corrupted".  
My old jpg files i saved on the previous computer still work to upload no problem.  I have double checked that Gimp is still exporting as an RGB format, and have tried all sorts of other stuff to no avail.  The exported files are definately a .jpg but they are no longer recognized in Canva as compatible.  I have also updated my browser as well.  Does anyone have any ideas on how to get this to work?  I work with Canva all day long and now can't upload any of my files, I have no idea how to fix this.  
I wonder if i should download the older version of GIMP, since it still works on my old laptop but not the new version on my new laptop.  What could have changed?

I am not an advanced user but would like to ask this. I used some command to install Gmic and MyPaint brushes as suggested by @rich2005 on another thread. But looks like there is no MyPaint brushes in my GIMP brushes tab. What should I do ?

I just loaded GMIP and am trying to see if I can use it for stacking up many pdf layers of a map.
I'm using white as the transparency color for each layer and have not found a way.
Can anyone help point me in the right direction?

Hi, I have a new install of Windows 10 Pro x64. I installed Gimp 2.10, but when I go to launch it, nothing happens. I started the gimp console and I got these error messages:
