I was wondering what happens to metadata in Gimp. I was having fun playing with some programming languages to create an image editor. I understand that in broad terms the structure is this:

I have a .jpg photo that I want to edit, I upload it to the editor, the editor generally uses an external library to read the .jpg file; it takes this file, decompresses it, isolates the bits relating to the actual image which will form an array of pixels of the exact dimensions of the image that will be shown on the screen.

At this point each editor will have its own functionality for editing the photo.

Once you have achieved the desired result you can export the photo again as .jpg. The edited pixel array is taken and compressed again into a .jpg file via an external library.

I wanted to understand what happens to the metadata in this process in Gimp. I tried to read the Gimp source code but I didn't understand.

I'm interested in understanding well what the final exported .jpg image is made of. If it is composed of the compressed pixel array of the edited image + some metadata created by Gimp useful for the final file (Such as resolution and size) + any metadata from the original file that Gimp recognizes and copies into the new one (Asking you during export if you want to keep them or not and allowing you to modify them).

Or could it happen that Gimp adds metadata present in the original photo to the final .jpg but does not recognize it and does not show it in the metadata viewer or editor?

If anyone knows any places within the Gimp code where I can understand this, it would be very useful for me.

I have a background layer and I want to paste a transparent image to it. I.E I do a Google image search for ‘trees transparent’ and receive a full page of results. However when I select a result with a checkered background vs an image with a white background. Only the ones with the white background copy and paste correctly. The ones with the initial visible checkered background do not. (Pasted image also includes the background with these). I was wondering why..

Sorry, I'm a beginner in gimp. 
I have a picture with white text on black background. First I want to remove the text. I try using the klone tool. I use the ctl-key for marking the source spot. But the klone tool does not do anything. 
I would appreciate a help tip

Hello, would love to see feature like blender or gimel the node-based editing

I'm new here, so hi.

After optimising for an animation, is there a way of exporting the list showing in the Layers Editor as a text fiile?

For Example:
----------------

img001.jpg(100ms)
img002.jpg(2000ms)
img003.jpg(200ms)
.... etc

cheers Sean.

By default, the Move tool auto-picks the layer of the top most-non transparent pixel where you click. So, starting with such an image:

   

   

   

I rebuilt my pc about 2 months ago and reinstalled GIMP.

Sometimes when I am editing or adding text, the text gets selected around the edges of the font, like it was an image.  But it's just text..  I have not done anything to the text.  And sometimes it does this to other text on the screen that has nothing to do with the text I was working with.  Like 1/3rd of the text layers on the screen.  This happens randomly and I have checked in the Preferences and tools, but found no setting that would do this...

Any Help is appreciated.

   

Hi Folks, let's say i 've got a picture on my phone and I edit it adding a crossed out to the image using the pencil tool. Can I remove that using the gimp?

Thanks in advance

Hello all,

I am back with a continuation of my project from my last post. I have 60 images that start at 420x37 and decrease in length by 7 pixels per image like so

   
   
...
   

What I need to do is make all of the images back to 420x37 by putting a transparent edge on the left side like so
   

I am on the right track using canvas resize with an offset to move the image to the right. Everything looks fine in Gimp but when I try to flatten the image so that I can save the new file I get an error.

Also is there a way to automate the process for all 60 images?

Thanks for helping out a newbie!
