Center montage in resulting page

[binarymelon]

I'm trying to tile some images (custom playing cards) in a pdf for printing and I'm running into some issues trying to center the resulting montage. I'm using the following command:

Code: Select all

montage -density 300 -tile 3x3 -geometry +20+20 *.png -gravity center -page 2550x3300 output.pdf

and getting this output

What version of IM?

What does "-gravity center -size 2550x3300" do? I suspect it has no effect.

Please show a reproducible example. This means something that other people can try out, and compare their results to yours.

I should also add the size flag was incorrect (should have been page). I had been trying a couple of things and must have copied the wrong command.
