Hi there,
Does anyone know how I would go about turning an image into just it’s four primary colors (and black), and then saving each of those colors as it’s own layer/png? Is there a plug-in that does this for you? I am trying to make multi color stencils....

Krita brushes |

Since I got a lot of help regarding GIMP brushes and how it works, I turned to Krita and really love how the brush and brush strokes work in it. The default brush set itself is impressive. I would like to ask whether there are any reliable free brush sets available for it. I am not much of an artist and mostly look forward to using interesting brush stroke images. It will be nice to get some help with this. Thanks.

Background removal |

So I am totally new to GIMP (or any other editing software).
I am attempting to clean up an image my daughter drew for use on redbubble. I scanned the image she drew by hand, it scanned very well. Now I need to remove the background so it can be printed on other than white items without a giant white box around the image. I used the foreground select tool. I will try to describe step by step what I did.
Open image.
Add Alpha Channel
Click on foreground select tool
Draw a "box" around image
Click Select in the Foreground Select Dialogue box
"Paint" in the image
Preview mask to verify image
Click Select in the Foreground Select Dialogue Box
Click Select > Invert
Hit Delete on Keyboard
At this point the background is checkered, so I think removed correctly. From here I did the following:
1) saved as .xcf but redbubble cannot open .xcf files
2) exported as .jpg, but when I opened the .jpg in redbubble, the white box remained.
I am sure I am missing something terribly obvious but cannot figure out what I need to do to save a .jpg (or .png) with just the character (or transparent background) for use on redbubble.
Please help!

databending and raw import settings |

Hi all,
I have been trying to find image software for Ubuntu that can replicate a databending process I figured out on my mac. I used GraphicConverter 11 to import a .wav file as raw data, transferred the resulting image to GIMP and modified it, exported that as .bmp, and then used Audacity to import the .bmp's raw data, coming full circle back to audio.
I got my best results when I imported the data as a Grayscale image in Unsigned Long format.
With those specifications, aspects of the original file were recognizable in the altered version, and it was not totally destroyed. As a matter of fact, the end audio only differed significantly from the original if I actively edited it in image form (the IWarp effect is great for this). This process yields a very clean transfer.
I now have a new laptop with Lubuntu 18.04.5, for which GraphicConverter is not supported. I tried importing raw data with GIMP, but the import settings do not seem to include Grayscale or Unsigned Long. I've tried a few other image-editing applications, including Converseen, UFRaw, and RawTherapee, but I haven't found anything that will do what I need. Is there any way I can get GIMP to do this, and if not, is there another program for Ubuntu that may work instead?
