Is it possible to export the different pieces of a selection into PNG images or put it at once in a new layer for each ?

Let me detail below what I'm trying to do.

1. Open image like the attached picture
2. Select white background
3. Invert selection
4. Grow selection by 20px

The next step is to save the different pieces into separate images. Is it possible to do it with Gimp ?

Hey guys, 

I have a logo that I am trying to make the background transparent. However, I am struggling because there is a few white/ light colored portions contained in the logo. Every time I use fuzzy select it does not select these parts of the logo and makes it transparent along with the background. I have tried using the lasso tool to touch these sections up, but they are individual sections so I cannot select the whole image at once. Would you suggest making individual layers for these parts and then incorporating them back into the image after I have made the background transparent? Thanks in advance for the help, I am open to any and all suggestions!

Thank you,

PM me if you need to see the logo to make better sense of what I am trying to accomplish.

Problem. I'm using software that outputs many JPGs and alpha JPGs like this:

   

Using this ImageMagick command I can combine the 2 JPGs into a 1 transparent PNG:

composite -compose copy_opacity frame_0000000_alpha.jpg frame_0000000.jpg 0000000.png

That works perfectly but I want to do hundreds or thousands of PNGs.
I tried this:
composite -compose copy_opacity frame_*_alpha.jpg frame_*.jpg *.png

It looks like the output filename doesn't work. Does anyone know how to convert these combined JPGs to PNG's?
Is there another Open Source method to achieve this?

I have created the picture below for a wallpaper, and I want to blur/fade the edges of the tweet (which is a separate layer). How would I go about doing this?

Hi all! I am hoping someone around these parts can help me out    I have been using gimp for years, so I am fairly familiar with the basics of it. The majority of the things I use it for all revolve around the same tools, so I am pretty unfamiliar with gimps full potential.

I have searched the internet high and low for some help and I am just not having any luck 
I have got some 360 images taken of a model, and I am trying to delete the background of them to make it transparent, which will be easier for me to work with. The problem I am having is the background is a rough black/grey (from both the pedestal and backdrop), while the model has black/grey on it as well... I have attached 2 images of the model, just to give you a look at what I am working with...

I have tried everything I know, and it is just not working out 
The fuzzy select tool either does not select a good amount of the background, because it isn't very solid, and when I bump up the threshold it starts to select the black parts on the model.
I have used Color to Alpha in the past for many related projects, but due to this model having so much black on it, it is just not working well at all!
Foreground Select is the best I have worked with, but it does not give good results around the black parts of the model since it is so similar to the background.
I have also tried a couple different layer modes to see if any of those will get rid of the background, but again, no luck 

I thought there was a way to delete similar parts between 2 images, but at the time I need it most I am unable to remember anything   The backgrounds are very similar in some places, and identical in others, its just the model position that changes, so I figured it would be fairly easy, but that is turning out to be wrong 

I am hoping someone is able to help me out... I am hoping there is a simple solution, as I have almost 50 images to do like this one...

I'm a newbie with GIMP, but can't find the answer to this in the manual. It's probably trivial.

I'm trying to use GIMP to extract parts of imported PDF files and assemble them into a new file. I imported at 300 ppi and created a new page at 300 ppi. But when I copy and paste the pasted image isn't the same size as the original. I've no idea what the original pixel density of the PDF was.

Is this expected behaviour, and how can I get the correct size for the paste?

Hi, I'm new with Gimp.
I tried to install it yesterday, version 2.10.8, on Windows 7, 32-bit, but when i open it and try to open a file to edit, it crashes, and says:

'GNU Image Manipulation Program has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.'

Please help, how can i fix this?

Thank you.

When I want to open a file in a subdirectory, and I open a  networkdrive, I can't browse through the directory tree. 
Eg. I open a drive M: with DIR1, DIR2 and DIR3 in in it, and I want to browse further in DIR2, I get an error: 

Could not read the contents of DIR2
Error when getting information for file "M:\DIR2\DIRECTEUR": Input/output error

It seems that GIMP wants to read the complete tree, and needs access to all. The directory DIR2\DIRECTEUR is not accessible to me, but others in DIR2 are, and that's where my files are. So the only possibilities are Open Location... where I have to know exactly where the file is and how it's called, or browsing with the Explorer to the place, abd use 'Open with ...' there.

Why can't I browse from within GIMP? What can I do?

Hi
I'm trying to make an animation that can play over a video. I have 20 files saved as .png so that the end file can be placed over a video so that it shows through the clear area, but when I run the animation playback all the images remain on the screen. If I save them as jpgs of course it's fine.
What's the best way to do this whole thing?

Playing with:
- Neon Edge
- Wind plug-in
- Gradients
   

edit.
maybe this time I got a better result
