I'm doing a quick mask and kept "saving to channel" to make sure I wasn't losing anything, so I have 3 different channels now titled Quick Mask, Selection Mask copy, and Selection Mask copy #1. i imagine this must work like the layers where everytime you save a new channel it starts saving only on that one because it becomes the new selection, meaning the older channels don't have the new work on them (assuming you don't go out of your way to click back to older channels)? Although I'm testing out the channel visibilty and the only one that seems to have all the work on them is that original channel titled Quick Mask. The other 2 both look the same with seemingly nothing selected. Not sure why it looks this way. I guess I might as well delete the seemingly blank channels?

I'd still like to know though if there would be a way to merge them all, for future reference

Whenever I export to .png it is a HUGE file... How do I export it into centimeters?

How  do catalogs frequently manage to get pictures of the items they're selling with a perfect white background that contains nothing to distract the viewer from the product? For instance, if you go to Home Depot, every item has a white background containing absolutely nothing.

I simply don't believe that each and every item was photographed on a perfectly white surface that shows absolutely nothing else, not even texture. There *must* be a technique for removing the actual background that was present when the picture was taken yet preserving the border of the item perfectly. I'm very curious to know what that technique is and if I can do it in GIMP.

Even just knowing the name of the technique would be helpful but a link to instructions or a video detailing the technique would be even better.

Is this a bug or what should I do to be able to use the Decompose CMY filter?

I can use Extract Component - CMYK (C, M, Y and k).

But when trying Decompose CMY the following error message appears:

I feel like the answer must be simple but I can't find it..I increased the canvas and it rendered the original area in a square and anything outside of that it doesn't paint on. How do I make it where it's all considered the same space?

Hello,
I am new to Gimp and script processing and I could not find the name of the procedure for the following feature in Gimp:
Filters -> Enhance -> Noise Reduction.
I would like to use this function in a script.
Does anyone know how to address this procedure?
Kind regards

I'm using 2.10.12 Portable and after editing a photo, all of the pointers changed into what looked like a small line in each of the 4 corners. This was for at least the pen, pencil, and eraser. I couldn't get it to change back to a normal pointer. I closed and restarted GIMP and now the enter GUI is gone except the file, edit, etc menu, and none will reappear if selected in the window menu. Any idea what happened?

Hi all,

Why is there a difference between the coordinate values displayed between Pointer and the X, Y of the ruler?
Pointer always displays the last pixels outside the image area.

If the image is 1000 px wide, the pointer displays the location of point x = 1000 equivalent to point x = 1001 of the ruler.

The same goes for the Y coordinates:
If the image is 100x20 Px, Pointer displays points 100 and 20 outside the image area.

Is there any setting I can adjust to make both systems the same; displaying the same values for the same points on the screen?
   
Thankful.

I looked everywhere on USB drives but couldn't find this script, does anyone have a copy of "Will's Script Pack" I think it's filename was 'wills-animerge.scm' or similar.
Also I'm in need of another script (I think it's an .scm, but it's possibly a python file), it makes the background layer appear behind (assuming transparency..) or overlaying all the subsequent layers which is handy for animations. I know it would help if I knew the name, but unfortunately it escapes me right now!!
Thanks

So I know how to make an outline on the outside of objects and text, but how do I do this in the inner areas of text?
For instance , take the letter "B".

Also, how do i remove this irritating "Tool options" tab from the left hand corner of Gimp? It's blocking things in that area of my screen.

Thanks!
