I understand both trim and the rectangle tool but when i try to cut or trim the top off an image, it leaves an alpha layer visible. I want to have a clean cut that will cut the top of the image off clean. Can anyone help me? Thanks, I have been trying to do this for 2 years. (I do not want to leave a transparent background)

You don't say which version of GIMP you are using - the following applies to V2.10.22.

Use the Crop tool and in the tool options make sure that "Current layer only" is not selected but "Delete cropped pixels" is selected.

Thank you so much. Using 2.10.22 but I cannot find any place in tool options or preferences or with the tool that that has "current layer only" and neither can find "delete cropped pixels" Maybe it is right in front of me but I don't see that anywhere.

I go to the crop tool, next, I place the crop window where I want it to crop.

After that, I understand that I can double click or use "cut" under edit.

And I did that once and somehow it worked. I failed to use "nohalo" and it became very pixelated.

(at this point, I'm not even sure how I did it) So with the above information, what can you suggest for me? I appreciate you taking the time to help! Jude

Just realised what the problem might be. If you go to "Windows/Dockable Dialogues" is "Tool Options" selected? If not try selecting it.

I read that checking the nohal would prevent the pixels from moving around, but maybe I misunderstood the article. Thank you for all the additional information and image of the tool options, I will follow your instructions and let you know when I am successful. Jude

There we go! That did it. A million thanks! Jude
