Convert creates multiple files
I want to crop an image and am using convert


Code:
convert mountain.png -crop 3000x4500 +repage -format png mountain--cr.png

The problem is that convert is creating 4 files



Code:
mountain--cr-0.png
mountain--cr-1.png
mountain--cr-2.png
mountain--cr-3.png

The first is what I need, the other look empty

Just for fun, have you tried to resize the image before you crop?

-resize geometry resize the image

Using the following command did not work, still getting the 4 files.



Code:
convert mountain.png -crop 3000x4500 +repage -format png -resize 3000x4500 mountain--cr.png

Maybe try resizing first, for fun....

Code:
convert mountain.png -resize 3000x4500 mountain-resize.png
convert mountain-resize.png -crop 3000x4500 mountain-resize-crop.png

Or something similar and simple, step-by-step?

Just to see what happens?

I have an image with a big canvas, and the image falls within it. I am trying to crop to the size of the actual image.
