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?

This seems like it should be a standard use, so I'm sure this is just a setting I'm missing, but I can't figure this out. Any suggestions appreciated.
I have a group of photos of people taken against a blue background (although it's not completely uniform). I want to remove the backgrounds, so I just have the images as cutouts.
I've used the foregorund select tool to create a selection around the person, but whatever I do to then delete the background, some remnants of the blue remain. These are outside of the selection line, so I'm not sure why they are not deleted. Images below illustrate what I mean.
What I have tried:

1. Foreground select (based on Compound colours).
   
2. Remove holes.
   
3. Cut the selection.
   
4. Paste to new layer.
   
5. Delete old layer.
   

1. Foreground select (based on Compound colours).
   
2. Invert the selection.
   
3. Remove holes.
   
4. Add alpha channel to the layer.
   
5. Delete the (inverted) selection.
   

Hello!

I am new here and need some help!


So my wife made some tea dyied paper that I scanned... Problem is that because of the fluids the paper is not flat anymore.


You can clearly see it on the scan (shadows)

Now I tried a lot of youtube tutorials but it never fit my situation.


Does someone have a tip for me? A solution?

I would appreciate it very much!

EDIT: here is part of the picture attached

I have some images saved, in the past I reduced the size of the images a lot to save disk space (for example, I reduced an image from 3840x2160 to 1280x720, that is, 200% reduction).

Now I need to go back to the original size, and well, that's a problem, because I kept these images for other people, and these people want the original image (they cannot suspect that the image quality has been reduced).

I know it is impossible to increase with the original quality, but what is the best algorithm to increase the size of images in Gimp to get as close to the original? To me, NoHalo looks the best, the others seem to blur the image.

There are some sites that promise to increase quality using AI for free, but what is the guarantee of privacy? I don't want private images stored or posted around. And it is very suspicious of a website doing this for free.

Not that easy to code, but the results are worth it:

   

   

I have made a business card in GIMP and i need to export it to PDF for the printers. 

First, I tired to export it with all the layers still in the image. Exporting that that resulted in all my text bunched up.. A jolly mess. 

So, I 'Merged Visible Layers' on the whole thing and exported that. 

That almost worked, but the output pdf has added white space to the right and under the image.  Around 4 pixels to the right. And a 1 pixel row across the bottom. 

How can I fix this?? 

Thanks.

This seems so simple, and it should be.  

It's not.

Once again, I have created an (irregular) selection in Gimp.  [[It is not a square, or circle, or rectangle, or anything 'easy' to work with.]]  I cut it out with the free-select scissors.  I have the 'marching ants' to confirm that I completed the selection.

Once more, I have copied the selection (both Ctrl+C, and from the Edit menu).  Once more, I have attempted to paste the selection into a new layer.  Once more I have created the Floating Selection.  Once more, I have attempted to anchor the Floating Selection into a new layer.

It simply does not work.

I've seen and read maybe a dozen tutorials on this.  I have followed to the letter the steps illustrated or described in the tutorials, over and over.  

I always wind up with one of two results:

(1) An 'empty' selection in the new layer -- the 'marching ants' outline is there, but the content inside them is not.  Or,

(2) A visible selection which cannot be operated upon, or moved, or manipulated in any way.

Is it possible for someone, anyone to provide ONE (or two) method, which will (1) successfully paste the selection onto a new layer, and (2) allow me to work on that selection in the new layer?  Something that will work at least 80% of the time?

If I sound frustrated, it is because I am.  I apologize if that comes through.  

I'm merely seeking something that works, and something that is (mainly) reliable.

I thank everyone in advance for their answers, and for their patience with me.  It is appreciated.

HI,
I am trying to apply some filters from Gmic, but I get error like these. These errors mostly occur on color filters. Most other filters work fine. Any suggestions for solving this?
I have working network and when I try to acces given url on browser, I can access the files just fine.

I am using Gmic that comes with Krita. Is there an additional step to install/use Gmic?
I am on Windows 10. I am using Krita 4.3. I even tried it with Krita 4.4 alpha, but still got error. Honestly, This error has always been there for me since I started using Krita few years ago. I always thought maybe these filter are discontinued or something.
But I saw people using them on youtube tutorials, and I couldn’t access it.
Is it something to do with my hardware? I have very old laptop. 4 gb RAM and nvidia geforce 820m 2gb.

I posted this on Krita forums and was directed here.

I've scaled images in GIMP 2.10 and imported them into an Internet Webdesign program called BandZoogle without any problems before.

I just received an image from a graphic designer that I need to scale down and the scale feature works in GIMP but does not transfer properly.  In other words, the image remains the original size once it's imported into BandZoogle.

What am I missing?
