Batch composite hundreds of images

Hi folks!

I've searched the forums and tried several methods but i am unable to get what i need to work.

Basically i have several hundred images which i would like composited onto a single common background.

Common background image:


Sample Image:


Result:


I am currently using the following code:

Code: Select all

composite -gravity center -geometry -0+5  top1.jpg  back.jpg  composite_top1.jpg

Is there a way to accomplish this in batch?

Thank you so much for your help!

You could put it in a for loop, for example:

Code: Select all

md newdir

for VAR in $(ls *.jpg)
do
  echo $VAR

  composite -gravity center -geometry -0+5 $VAR back.jpg newdir\$VAR
done

Hi snibgo,

Thank you very much! I tried what you mentioned. I put your code in a .sh file ( composite.sh ) and ran "sh composite.sh" from Ubuntu terminal.

Nothing happened expect the red back.jpg file was duplicated to a new file called "newdir$VAR"

Am i doing something wrong ?

Thank you

Yeah, my fault, sorry. For bash, use forward slash "/" as directory separator. And use "mkdir" to create a directory:

Code: Select all

mkdir newdir

for VAR in $(ls z*.jpg)
do
  echo $VAR

  composite -gravity center -geometry -0+5 $VAR back.jpg newdir/$VAR
done
