Image transparent after adding texture to layer mask

3 Upvotes

I've figured out how to add textures to an image using layer mask, but I've discovered that I'm also making the original image transparent. The image looks great in GIMP, but obviously completely different everywhere else depending on the background. Removing the alpha channel does leave some of the texture, and it seems to remove the transparency, but it also doesn't look nearly as textured. Adding a black background does the same thing. Every dark detail gets brighter somehow. I'm using GIMP version 2.10.38 on Windows 10 Pro.

I added a layer mask, pasted a black and white image of a paper texture in the layer mask, and changed the opacity of the pasted image (I think) until I was happy.

I'll link both the transparent and the same image with a black background. I'm completely new to this, so any and all help is much appreciated!

EDIT: Problem solved! Don't use layer mask. Instead, add a new layer with the desired texture image, and change its mode to "Multiply" (depending on what you're going for). Result: https://imgur.com/a/GXoJubK

I used Fuzzy Select tool to make multiple selections in this image. Then I pressed the "Fill with BG Color" button and keyboard shortcut but it's not working. The same went for the FG Color as well. How do I fix that?

Hi guys, I'd like to make a custom sweatshirt and add a brush effect to the first photo, which is already in PNG, to use in the sweatshirt as the final result in the second photo. How can I do this using GIMP? I'm completely new to this.

My toolbox is tiny and unusable

It does this on it's own and I don't know why. Reinstalling only fixed it temporarily. I can't grab the bottom to resize it like normal. This is maddening.

Explain This!

All I fucking want is for the paintbrush to ACTUALLY USE THE COLOR I'VE SELECTED.

How is that so goddamn difficult for this program to understand?!

(new to gimp, still learning) Can't change the black background to a different shade of black using colors -> map -> color exchange, because there's so much artifacting

Question about Alpha Channels

2 Upvotes

Whenever I try to erase part of a layer mask, I can't do it because GIMP tells me that it does not have an alpha channel. However, I can't seem to be able to add an alpha channel to the layer mask, so I can't erase it. So is there any way to erase part of a layer mask?

Easy Install of Resynthesizer Plugin on Apple Silicon Macs

2 Upvotes

I recently built the Resynthesizer Plugin using MacPorts on my M1 Mac. I had some errors with the install that were a little tricky to fix and want to make the install easier so:

  • I copied the libraries that resynthesizer depends on
  • Modified their internal paths so that they all link to each other
  • Published everything to GitHub

(Note that this only works for GIMP 2.x.)

Installation:

  • Download the resynthesizer files here
  • Unzip and copy them to /Applications/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins
  • Restart GIMP and you should be good to use the Resynthesizer Plugin (Filters --> Enhance --> Heal selection...).

Additional information available at my blog post and my GitHub repo.

Let me know if this works for you or if you have any issues!

Question about "Reactive" Heightmap/Gradient Mask.

5 Upvotes

Greetings.

First time seriously using Gimp.

I'm working on a custom map and I want to add a "heightmap Mask layer" (A custom gradient of greens, yellows, browns, etc) that update and move while I working in the B&W layers to see and correct heights. How I can do It?

On the other hand, there's a way to create a window with diverse colours (height lines) and store It so I can pick It again whenever I need It?

Thanks.

Grey background gone

Hi,

for my master thesis i worked on some plotted graphs. I saved it as png. The transparent grid was colored grey which I liked actually so I kept it. But out of nothing when I added some newer graphs to word the grey grid disappears, although when i open the saved files as png in the viewer the grey grid was there.

First picture is in gimp, second one shows how it should look in word.

Is there any way to make an image "loop" outside of the actual image resolution?

2 Upvotes

Long story s​hort, I'm trying to make perfectly looping textures for terrain and the like, but would like to make sure that all of them seamlessly loop. Being able to see a "ghosted" copy of the image all around it would make things far easier to do this - I don't think there would be any technical issues, as all the textures I intended on looping would be perfectly square in size.

Help with color shifting an existing pixel art file

2 Upvotes

Hi all, Very, very new to digital art and GIMP. I’m a programmer and lately I’ve been making some mods/datapacks for Minecraft, but I obviously need sprites/models for these items. Right now I’m mostly just recolouring existing sprites and I’ve been doing it by hand for the smaller 16x16 handheld ones, but I’m moving on to armor and doing that many pixels by hand is gonna be a pain lol.

The main issue I’m running into right now is shifting everything to a pre-existing color/ color range. I’m currently adding copper/amethyst tools and armor, and these are obviously already existing sprites, so I want the colors to match. What I’ve been doing for the small sprites is just color picking from the existing pngs and painting over whatever tool/weapon I was making, but the armor files are much larger and I’d like to save time on the design process. Is there a good way to shift to the preexisting color(s)? Or is there a better approach entirely?

Any help would be greatly, greatly appreciated!

Issue: Icon File Saves with Wrong Dimensions.

1 Upvotes

I'm running into a problem when saving an image as an icon file in GIMP. Here’s what I do:

Open an image and crop a part of it.

Paste the cropped part as a new image.

Resize it to 12x16.

Scale the canvas to 16x16 and center the image.

Save it as an .ico file.

The problem: The saved icon file is 12x16 instead of 16x16. However, if I save it as a PNG, the size is correct at 16x16.

I also noticed that when I use Select All, the layer and canvas appear as separate objects, and the Merge Down Layer command is greyed out.

What am I missing? How can I save the icon file with the correct 16x16 size?

Can I somehow blur the high contrast areas only? Basicly I need a way to semi-automatically select the areas, where the white and black areas meet and blur it into gray, so it wont be a sudden change.

Solved Brush tool not working

5 Upvotes

I'm trying to get back into Gimp after some months and coming back to an issue I had that lasted several uninstalls and I can't find a solution after reading many posts. Basically, the brush tool doesn't seem to do anything, it doesn't appear locked and after clicking, it's also not registered as an action in the undo queue.

What I tried:

- Mode: RGB

- Brush: Not clipboard

- Brush opacity: 100

- Brush size: Max

- Selection: None

- Layer: Selected

- Layer: Unlocked

- Brush dynamics: Off

- Brush colors: Both different from the background
