In Gimp is there a way to scale an image down without losing image clarity?

I have some images in various layers. I flattened them, then scaled the result down from 6.88 inches wide to 6.5 inches wide (with the height also scaling down automatically in proportion).  But the image clarity on screen before scaling down was better than after scaling down. 

Thanks for any assistance.

I think I see how, now. The problem was that when I scaled down, I did so by changing the image size directly, while the resolution (300 ppi) remained the same.  So by reducing the size, i was also reducing the total number of pixels in the image. So instead, I changed the image size by increasing the resolution.  By raising resolution from 300 ppi to 317, the image automatically shrank to 6.511 inches wide (in printing). Because the total number of pixels in the image remained the same, compressing more pixels into an inch, the total size of the image decreases. But you have the same number of pixels, so resolution is not lost.  I think...

I'm writing a game for the open source Uzebox games console. Its tile conversion program expects the input to be one row of 8x8 pixel tiles. Currently, I have to prepare the graphics working by an 8x8 grid and then manually cut the sprites and other graphical resources into individual 8x8 tiles and then manually move each tile into a single horizontal row to keep the tile conversion program happy. Pretty tedious stuff.

This process would be much easier if there was a GIMP plugin to automate most of this process by turning a rectangular GIMP selection into a new image composed of a single horizontal row of (8x8, or whatever the user specifies) tiles.

Does such a plugin already exist?

Thanks!

Hi,

How can I know that when I export a gimp image to pdf, that the original gimp resolution is preserved in the pdf?  

I created gimp images measuring 6.88 inches by 10.5 inches at 300 x 300 ppi. 

After I export one of those images to pdf and open the pdf in Adobe Acrobat, and set Adobe to display at 300px/inch, the image on screen visually appears MUCH bigger than 6.88 inches by 10.5 inches.  Maybe 3 times larger on the screen than that. That seems to mean the resolution of the pdf is far down from the resolution of the original gimp image, right? Yet Adobe has a little box at the lower left of the screen saying the image is 6.88 inches by 10.5 inches. 

So has the resolution gone down in the pdf?  

Thanks for any assistance.

GIMP 2.10.32 Release 1 (Apple Silicon) works with Ventura?

Been wanting to upgrade from Monterey to Ventura, but every upgrade on Mac has been a disaster.

Does this work please?

I took multiple photos of my dog Hunter running across the hockey rink. I wanted to create a multiple exposure so I blended them in Gimp using the addition blending option.

It isn't quite what I wanted: he appears rather ghostly and I wanted more of a solid appearance.

Is it possible to do what I want? If so, how?

   

I searched for this everywhere, but can't seem to find an answer, even though it has to be a common problem.

I have an object surrounded by a background, in this case the white. But the transition between the background and the object isn't entirely clean. As you can see some of the pixels close to the border are a little darker.
If I change the background or select the object, it will either cut the transition pixels off and make the result seem cut out, or have this thin gray border around the object.

So is there a way to take the slightly darker white-ish pixels from the white background and transfer them to the new background, but not as white pixels but what's darker than white onto the new background?

I don't want to cut all the white inside the object, this is just about the cut-out.



Thanks

(New User)  I'm having a hard time seeing some of the brushes(tools) on the canvas.Especially on a transparent background..The heal and clone tools..  Is there a way to make them thicker or change colors so they can be seen better?   Thank you

Hi, wondering whether it is possible to create a text effect like this


   

I don't know what they call this. I have seen this kind of text in Lord of the Rings, Harry Potter etc. Thanks.

Hi, I installed the dev version from Flathub on Ubuntu 22.04. Now I cannot see my 2.10.32 ( also installed through Flathub ). Is it lost? Any way to get it back without removing 2.99?

Thanks.

Hey everyone,

Total novice to gimp or image editing in general. I'm trying to copy/paste an image into another image, and whenever I cut out the image and paste it, it seems to lose its color quality or something, I'm not even sure what it's doing. I'll attach a picture to show what I mean.

If you know what it is I'm doing wrong, I'd really appreciate the input!

The left side of the attached picture is the original quality, and the right side is after I cut/paste on gimp.

Thank you!
