hi, thank you for sharing these. Glad to see IM getting better at this type of thing!!

You have to be using IM 7 and then there is a different syntax that needs to be used. In IM 7, you can do magick image1 -set option:mysize "%wx%h" image2 image3 ... imageN -resize "%[mysize]" result.png You cannot do this in IM 6. You still have not provided your IM version! This command :)

Its neat that imagemagick 7 has that command - it would be even better if it can also name the end files properly

My solution was to first get the image size by using
convert image -format "%w x %h" info:

Then resizing with mogrify. I however couldnt get it to do it in a single command

I am new to nesting commands in imagemagick - thus why i needed help for the channel mask syntax

Nevermind, I found another solution

Can mogrify extract the size of the first image as well? I've been using it in other cases too btw

@fmw42 How do you also tell the result images to have the name of their target counterparts? Yes, I want to overwrite the originals

Ok It worked after I removed the '...' and 'imageN'

I still get errors and no result unfortunately : magick out.png -set option:mysize "%wx%h" b.png 2m.png ... imageN -resize "%[mysize]" result.png magick: unable to open image '...': Permission denied @ error/blob.c/OpenBlob/2695. magick: no decode delegate for this image format `' @ error/constitute ...

I am Using IM 7 ! Sorry

@fmw42 How do you do it in one command line? The example code gives me errors and nothing happens to the images >convert out.png -format "%wx%h" info: convert b.png 2m.png ... imageN -resize WxH resultimage convert: no decode delegate for this image format `INFO' @ error/constitute.c/Re adImage/508 ...

@snibgo - your solution is so far the best one! It seems to resize the three images to the size of the mask.

Is there a function in imagemagick's arsenal to resize a number of images to the size of a target image? Without the need to encompass it in a script.

Ah I see. This is good to know as a precaution. I guess at this point I am more interested in using the size of image one as target size for images 2,3,4 and so on - I can use that as a common operation to make images the same size before doing operations that wouldnt work with them being different ...

I'm on windows, but also linux. The images have the same aspect ratio, but different sizes.

I guess this time I am looking for a separate command that takes the first specified image's pixel size and sets all the next images to that size

Thank you guys - I learned a couple of valuable tricks in imagemagick.
