some  "eye" symbols, indicating a layer is visible, have a background. what does it mean. how do i get rid of it?

can i change the line widths in all the layers within a group layer? 

for example, if i select a group layer and then select pencil and change the pencil width, will all the lines within the group layer change?
if not what do i do so that i can change all the lines in a set of layers?

thank you

I have a Jpeg of a line drawing. There are blue and red lines. I want to fill in the blue sections and change all the lines red and blue to black so I can make a Cricut cut file from it. Is there an easy way to do it?? I know it's a broad question....

I've attached the JPEG...

'lo everyone!

I'm new here, but not new to Gimp and I can use it to do a great many things.  But, one thing I've never learned to do is to manipulate a texture so that one or more sides / edges align with existing curves. 

I know how to align one to freely drawn curve, but not how to align one with a curve that is already defined so that I can match it without distorting the texture. 

The specific application, at the moment, is to add an edge of lace around the bottom of a dress.  The curve is part of a UV map for a dress for a 3d avatar, so it will be seen on all sides and needs to align well with the bottom of the dress fabric so it will look right from all angles.

Can anyone walk me through doing that, if it's possible?

Hi everyone,
I have an original photo and need it converted in the style of Shepard Fairey but to a more colourised version. 
Can anyone provide me with a simple step by step guide, PLEASE?
I would be most grateful. 
Thank you.

I'm on GIMP 3.0.2 on Windows 10. Whenever I use the File-Open or File-Export dialogs, the files and folders are intermixed and sorted counter-alphabetically. When I try to fix it by applying alphabetical sorting, it resets back to unsorted the next time the dialog is opened. Is this a bug?

i try to place guide lines in centimeters (cm) or millimeters (mm) but that doesn't work
i have been working with gimp for a long time on an amateur basis but i never knew how to set it. yes on precent but not on mm or cm
how can this be solved?
software of gimp is 3.0. 2 and runs on a windows 11

Hey hello. I've been using gimp 2.10.2 for a very long time. Just recently now updated to 3.0.2.

When used to work with older version, I used to paste lots of sub-images into the main one, to then right click in any empty space from main image to keep modifying pixels or adding up more sub-images, but here in v3.0.2 after pasting first sub-image, I get some small black lines which indicate to be the limit from new recently made "layer".

In v2.10.2 I didn't use to have this problem. Its not like there were made new "layers" when posting new pixels or sub-images to main image. I know there is a command named as "Merge down", but would like to know if there is some option to keep the same old behavior I used to have in older GIMP version.
It would be tedious to be pressed Merge down each time to add up a new sub-image to each one of the files that have to modify.

Dont know if its called other way around to make it automatic, so sorry about ignorance and thanks a lot in advance.

Hi, I am in GIMP 3.0.2 on mac book, works perfectly, I need to add to a selection, the search says To add to a selection in GIMP, hold down the Shift key while making a new selection with any of the selection tools, and the new selection will be added to the existing one.
I hold Shift and nothing happens, I think these searches are not made for mac. Thank you

I am a novice. 80 years old.

i have a base image and a transparent layer over it.
In the transparent layer i have drawn, with a pencil tool, one line.

i would like to move that line. i have been unable to achieve that goal.

my experience:
* learned that the move tool is not appropriate tool.
* clicked on transparent layer with one line, thus making that layer active
* selected the line
   * by using the rectangular selection tool.
   * wondered if i had just left clicked on line if that also would have selected the line
      as the line was the only object in the transparent layer.
* moving selection with method one:
    * after rectangle appeared around the selection
    * placed cursor inside rectangle box but NOT within the handles.
    * left clicked and dragged the selection upwards. the frame
       moved, but not the contents.
* method two
    * after rectangle appeared around the selection
    * went to edit in task bar and clicked on copy (also tried ctrl c)
    * moved cursor to a new location
    * in edit clicked on Paste (also tried ctrl v)
    * nothing happened. if i had clicked on "CUT" the line would have disappeared.

Please help me understand what i am not doing or doing incorrectly.

ps.
Tried to attach the file. it was too large. BUT THE SYSTEM WOULD NOT ALLOW ME TO DELETE THE ATTACHMENT SO I COULD
