Copy attribute width to new image

[trebol-a]

Well, I think it is a simple question, but I cannot get a solution...

How I can to create a new image with WIDTH x HEIGHT of other image.
I need to make something like:

Code: Select all

convert -size [otherPictureWidth]x[otherPictureHeight] xc:black dummy.jpg

I solved with

Code: Select all

convert otherPicture.jpg -draw 'color 0,0 reset' dummy.jpg

but, how I can to create an image width the attributes of other image?

I would do it like this:

Code: Select all

convert in.png -fill black -colorize 100 out.png

out.png is then the same size as in.png, but entirely black.

Thanx, is very similar at my solution... but how I can to use the responde of "identify myPicture.jpg" in a convert order?
