1. Is there a way to taper brushes when using a tablet?
2. I don't like how the all of the brushes share the same settings. Is there a way I can have the eraser have one setting (size, brush type, etc) while the brush has another?
3. When I move layers around I like to move the current layer. I have to change this setting every time I open up GIMP. Is there a way I can change this preference?

Hi! I am wondering ir there's some way to erase an array of complete lines of pixels from an image. I want to convert am image to a ser of thin horizontal lines over an alpha background. Might that be possible? I guess it's easy with some coding. Thanks for reading!

I'm creating digital art in gimp which is printed in big sizes also(18"x24" 300 ppi).When I create the art I give the max dimensions to the image(18"x24" 300 ppi)
Now there are additional graphics and elements I want to add to the image-the graphics I want to add are 300 dpi but smaller in image size-so I need to scale them-so they fit my big document-I'm afraid that during the scaling of the outer graphics their quality will be lost-I'm trying to understand what happens to resolution if scaling-My main concern is the quality of the digital art-the final product-I need it to be 300 ppi at big size(18" 24")so just want to understand the wise way to use external graphics -and how to scale them without harm to the resolution and quality-I'm trying to understand what happens to the quality when I scale this external graphics-do they lose their quality? Does their resolution change? Does resolution in general changes during scaling?

| Layer opacity shortcut |

Hi all,
I've been using Gimp for years on a fairly basic level. Recently I have been doing a lot of image stitching - there's overlap in the individual images so I just bring them in as layers, reduce the top level opacity, match positions, return it to full opacity and merge down. Not difficult but repetitive.
I make a lot of use of keyboard shortcuts ("Accelerators") and the preset "10% more Transparent" is great but I generally need to press it 3 or 4 times to get a useable level of transparency.
That got me thinking about Gimp's scripting potential, something I've never looked at before - "set active level to 60% opacity" with a single keypress would be so useful for me.
I'm very familiar with html and Office VBA but my first looks at python-fu have me very confused. If I just want this function do I have to create a plug-in and register it then get it to appear in the list of available commands so I can assign a combination of keys? The python console itself is already pretty confusing.
I think I've got something that could maybe do what I want but I can't figure how to run it to see what happens in order to debug. Then again maybe I'm completely off track...
➤> image = gimp.image_list()[0]
➤> active_layer = pdb.gimp_image_get_active_layer(image)
➤> pdb.gimp_layer_set_opacity(active_layer, 60)
Any help with solving this would be greatly appreciated.

| Disaster from duplicating all the frames of a GIF |

I had something that I wanted to do with a gif that has only 3 frames, so I though, why not just duplicate each frame, then I'd have a 6-frame gif to work with... right? WRONG:
![[Image: combine.gif]](https://1.bp.blogspot.com/-OvS0Su_SPM4/WqtxDyyVZZI/AAAAAAAAATw/5EAQfNVDh1ozQ1XuKH-V88snnAsfYTsMACPcBGAYYCw/s400/combine.gif)
I DID unoptimize before doing anything, and the frames all looked perfect. I kept them all as "combine," since that's how they came, BUT, when I optimized at the end, Gimp switched a couple of frames to "replace"...?!! (This was the 2 frames that weren't the copy of the Background frame.)
So, I thought, ok, it wants to do replace, I'll make them ALL replace...:
![[Image: replace.gif]](https://3.bp.blogspot.com/-ichyQOzp1gU/WqtxEGMygKI/AAAAAAAAAT0/xx4gd8pv2tgWBQ4Vh1st3zhZic4zKawNwCPcBGAYYCw/s400/replace.gif)
So much for THAT idea, LOL!! I'm clearly missing something important here... I'd sure be grateful if someone could tell me WHAT!
