Separate images from one png all same size

[UgandanPastor]

Hi COMPLETE NEWBIE HERE, so as the title says , i want to make separate images out of one image of a car blueprint. the blueprint has got all the different views in the same image. I know i'm gonna have to use the crop tool , however i also want the separate images to have the same ratio w/o causing any distortions to the car views

You can split an image up by setting guides in position.
Split into three, drag horizontal guides from the top ruler to the image dividing lines, then Image -> Slice using Guides will give you three new images.
If you need the front/rear views separating, same method, drag a vertical guide from the left ruler into position then Image -> Slice using Guides

What exactly do you mean by that. All the same image size ? Pad the images out with empty space maybe ?

Thanks that was really helpful.

Yes, because i want to open the blueprints in Blender, it's preferable if all images have same dimensions. How do i pad the images out of empty space so they all have same dimensions?

You can search with google (BMW dimensions, look in images) to find the real dimensions and then compare then with the (scaled) dimensions on the drawing. If the dimension are not ok, you can scale them using the gimp tools.

All sorts of ways, but once you have your split up images, select the largest, and use Image -> Canvas size to adjust to a 'convenient size'
Repeat using the same size for the othe images. example: https://i.imgur.com/oyZSIRy.jpg
