This is a thread for the elite users.

Short story, I want to either fix the pan viewing on my Turcom 6610 tablet or have gimp treat the mouse and tablet as the same tool set.

I am running Gimp 2.8 on Windows 10.

I currently have an interesting situation where certain projects treat my tablet and mouse differently.  It used to be that my tablet and mouse (as I think it's supposed to) were being treated as different tool sets, and the tablet would have issues with the pan viewing where when I clicked the space bar, the window view would bounce a little and not pan where my cursor originally was. 

Over the last few weeks, I have been using this one file that I made which treats my mouse and tablet as the same toolset.  I have to click off the main canvas to switch between tablet and mouse, but it keeps me on the same toolset and it fixed the pan viewing on my tablet.  

My issue now is that I cannot recreate what I did with this file in order to have the mouse and tablet be the same toolset.  I can copy the file and the single toolset works in the copy, but I cannot create a new file from scratch and keep my single toolset function.  the new files also brings back the tablet pan viewing issues.  

Everything else from what I can tell works just fine between mouse and tablet.  Pressure sensitivity and mapping looks correct.  Drivers should be updated.  Any help or input would be appreciated.

Thank you! 

Okay so this happened out of the blue. Normally when I copy and paste something with an alpha background, the alpha part is clear so my background color only shows. Now for some reason it posts as black. I know most people will tell me to just set the black to the alpha color but this also messes up images that are already black and the alpha color change doesn't recognize. I didn't have this issue till today out of the blue and I didn't mess with any settings. This is what the image looks like online
   
this is how it looks when I copy and paste it.
   

Editing in a photo is fraught with peril, in the good cases the subject looks weird, in the bad case s/he looks dead. But using the camera flash often makes it necessary to edit the picture to fix these awful red eyes, which is why I tried with much interest a technique alluded to on Pixls.us, for a new RawTherapee plugin:

Quote:

1. compute the average of the G and B tones
   
2. if the R tone is 1.5 times greater than that average, replace the R with the GB average value.
   

1. Make a selection on the eyes. It can/ should include the iris, but avoid skin tones. Feather a bit
   
2. Make a new layer from that: Ctrl-C, Ctr-V, Ctrl-Shift N. Let's call it "Eyes".
   
3. Make a copy of "Eyes", call it "Red 75%", start Color>Component>Channel mixer, set to "Monochrome", set Red to 75%, and Green and Blue to 0
   
4. Make a second copy of Eyes, call if G+B/2, start Color>Component>Channel mixer, set to "Monochrome", set Red to 0%, and Green and Blue to 50%
   
5. Make sure that all layers are invisible except these last two, with "G+B/2" over "Red 75%" and set G+B/2 to "Grain extract". The result should be eyes with a white disk where the red pupil was (with a dark spot where the white spot is).
   
6. Open the Channels list, and drag one of the R, G or B channels to the "main" list to copy it.
   
7. Back to the Layers list, make a last copy of "Eyes", call it "Correction", start Color>Component>Channel mixer, reset "Monochrome", set the Red channel to R=0%, G=50%, B=50%.
   
8. Make all layers invisible except the original picture and "Correction"
   
9. Right-click "Correction", and "Layer>Add layer mask". Initialize to "Channel" and pick the channel you copied at step 6. You should now have a fixed image.
   
10. At that point, you are editing the layer mask of "Correction" so you can tweak the amount of correction by playing with Levels or Curves (the most radical being thresholding the mask around 200, but this can make the fix limits a bit more visible).
    
    

   

   

   

Hey, ive recently did a factory reset on my workstation and i've started to have some issues with gimp that i honestly cant track the source of.

The issue currently, mouse is behaving extremely odd, clicks don't always register, drop down menus instantly close after i open them, pointer always thinks it's using the Move tool and i have to click a bunch to switch from it, often having to alt tab or drag the window to use that window's contents.


here's what i've tried and other details.

1. tried both latest releases of stable and dev.
   
2. mouse: logitech g502, drivers up to date.
   
3. no gimp plugins other than Gmic, but problem persists with and on 100% fresh stock gimp.
   
4. windows, gpu, mobo drivers are all up to date.
   
5. the issue ONLY happens in gimp, pc working 100% fine otherwise.
   
6. this wasn't an issue prior to the factory reset, both versions of windows, driver, and gimp are the exact same unless they updated in the few hours i did factory reset which is unlikely.
   
7. not a keyboard stuck using shortcuts issue.
   
8. all settings are on default, like i said fresh install.
   
9. only thing i havent tried is rolling back to an older version of gimp. but would be odd since it's the same exact setup was working prior to fresh install.
   
   

I made a channel and then applied that channel as a layer mask to many layers. Is there a way to make changes to all of those masks at once, or do I have to change the channel and then set the updated channel to the layer mask in all of them all over again?

Thanks.

Is it possible for someone to help recreate the coloring of 2 gifs for just a couple of single images?

I've downloaded the script arrow.scm and can use it OK. But the arrow is black and I'd like it to be permanently red. I've found nothing in the script parameters window that allows me to change the arrow's color. How do I change the arrow color permanently? I'm on a 2017 iMac and new to Mac, having recently changed from Windows 10 to Mac. Thanks.

Hello there!


I am painting with pencile on paper and want to scan these pictures and then paint over it in black, so that you can't see in the end the pencile bt rather just the black paint from GIMP.

Here you can see my picture I painted with pencile on a piece of paper:


And here I tried to paint over it with GIMP but you can still see the lines I painted with my pencile:


Is there a way to let the pencile paint disappear?


Hope for you help and thanks a lot in advance!
