How do you cut out the centre of an image, bringing the edges closer together?
I need to cut a large number of columns out of a PNG image. The area I want to remove is in the centre of the image; I therefore want the left and right edges to be closer together after the cut.
I can't find an obvious way of doing this in Gimp or Photoshop CS5 (I am very much a beginner). I would really like a tool which lets me say "cut out 100 columns, starting 4 pixels from the left". Any suggestions?
Maybe someone else will come along with a simpler method, but the simplest method I can think of would be these steps:
Marqueetool to select the middle section that you want to remove.
Select > Inverse to select everything other than that middle section.
Copy and paste. This will create a new layer with an invisible center.
Select the right half and use the
Movetool to slide it over so the two halves are aligned.
Hide the background layer/original image.
Image > Trim with the bottom-right pixel.
