I want to vary my line thickness as I paint to match a style of an image, but can't seem to find how to input this setting I'm reading about, varying the mouse size with how fast you move it. I'm sure one of you GIMP wizards must know TIA

I have seen this effect used quite a bit for cell phone themes and I wanted to have a go of it with my dog as the subject. I found the bones of the procedure here, but it gave really poor results with the pictures I wanted to use. (Black dog doesn't seem to help here.)

I ended up having to dodge and burn different areas to get better results with the rodilius filter and I also used g'mics Might Details at the end to help it pop a little. There are certainly areas I want to tweak further but it's getting close. Any pro tips out there? 

       

Hi, I am new here, first post. I have been using gimp for many years but with the new version I was really pleased that I could finally add keywords in the metadata so that my images are searchable in my work's image directory. I need this function for work so was very disappointed to find that no matter what I try it adds this coding Type="bag" when I export it as a jpg. This is causing a problem with my work's image directory and I'm desperate to fix it so that I don't have to take on a photoshop subscription just to keyword. Can anybody help?

I've been using the quick mask function (maybe that has some connection?) and tried to export the picture as normal in a png, which I've done before on this same picture, but this time it exported as a black box, just the color black filling up the whole image. I was backtracking some steps so there's both an undo and redo option available, as in it's in the middle-- could that be why it's exporting weird? It let me save it as a file while in that middle state so I don't see why that'd interfere with exporting the image.

My goal is to import a couple third party Python packages for use with my GIMP installation. This will allow me to use these packages when developing a GIMP plugin. I noticed a few directories that may be of use. They are as follows:

C:\Program Files\GIMP 2\32\lib\python2.7

This directory contains a site-packages folder which contains packages such as requests and pip.

C:\Program Files\GIMP 2\32\bin

This directory contains a python.exe. When I run python --version in an elevated cmd at this directory path, the output is Python 2.7.16, which I assume is GIMP 2.10's version of Python. This is important because I have my own installation of Python 3.8.0 in my Program Files. If I'm anywhere outside of this path in the cmd, the version that outputs is 3.8.0.

I have added these directories to my PATH system variable and tried running pip install but the output tells me I have already installed the requested third party packages. The problem is that they are installed to my Python 3.8.0 installation. I'm trying to run pip install in the context of GIMP's Python environment.

Any advice would be much appreciated.

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?
