I have two images of different height which I want to join horizontally (i.e. side-by-side). I want the images to be bottom-aligned as well as to be separated by a 25 pixel wide white area.
With montage
I managed to get both effects separately but using them together eliminates the alignment specification:
montage [1-2].png -tile 2x1 -gravity south out.png # correctly aligns at bottom
montage [1-2].png -tile 2x1 -geometry +25+0 out.png # correctly adds padding
Using -gravity south -geometry +25+0
eliminates the alignment effect.
With convert +append -gravity south [1-2].png out.png
I can similarly bottom-align the images but I don't know how to add the padding.
Is there a way to apply both effects simultaneously?
