Is it possible to merge multiple 'montage' command ?

[MrChristo]

Hello everybody
I have a script that takes 4 pictures and duplicate them to have 8 small pictures in one.

Here is what i expect : http://img11.hostingpics.net/pics/831624stack.png

I have a code that works well but it needs to save multiple temporary images. So I was looking if I could merge those command to have only one image saving. That would help to make the script faster.

Code: Select all

 //Make image smaller
    convert /home/pi/images/*.png -resize 487x296 -flop  -set filename:f "/home/pi/imagesResized/%t%p" '%[filename:f].png

//Make one col off 4 images
    montage /home/pi/imagesResized/*.png -tile 1x4 -geometry +0+15 -background none  /home/pi/line.png

//Duplicate to two cols
    montage /home/pi/line.png /home/pi/line.png -tile 2x1  -geometry +45+0 -background none /home/pi/photos.png

//Add the background
    suffix=$(date +%H%M%S)
    montage /home/pi/photos.png -geometry +20+247 -texture /home/pi/data/background_photo.png /home/pi/photo_${suffix}.jpg

Is that a good way to do it ?
Thanks everybody !

You did not provide your version of IM nor platform. But I assume you are on Unix. So the only way to combine these commands that I am aware is to pipe them. IM does not support combining directly between convert and montage. But you can combine successive convert commands by using parenthesis processing.

You asked here too,

but so far didn't even check back for an answer! (There are 3 now, even including benchmark data...)

This answer does so, successfully,...

...and it is getting the fastest benchmark result (a saving of ~28% in time when compared to MrChristo's 4 single commands).

But maybe with "combining" you didn't mean to include piping?

It still involves piping. There is no way I know to avoid the pipe and not write temp files to disk. Perhaps some one else has a better way.
