Insert text in multiple pictures (make a loop)

Question

My purpose is to insert a text (same words + sequenced number) into many pictures (may more than thousands), can I implement this using Mac or Windows? Thank you for the suggestions.

Answer 1

Using imagemagick software to insert text by command annotate, and write a loop in a script and then run it. This can be used to add a sequence of logical number + text into a sequence of pictures.

Answer 2

I would use OS X, and install ImageMagick using homebrew. First go to the homebrew website, and copy and paste the one-line installation script to install homebrew. Then install ImageMagick, like this:

brew install imagemagick

Then you can read this page and this page, that shows you a thousand ways to label pictures.

Now, use the Finder to make a new directory and copy some images into there to play around with without damaging your proper, original images. Say you make a directory called play in your login directory.

Then start Terminal, and type

cd play

to go to the new directory. Now you can make a script, something like this and save it as labelimages:

#!/bin/bash
i=0
for f in *.jpg; do
   echo Labelling $f, counter=$i
   convert "$f" -fill white -undercolor '#00000080' -pointsize 36 -gravity South -annotate +0+5 " Image - $i " "$f"
   ((i++))
done

Then you need to make that executable, just once, by typing

chmod +x labelimages

Now you can label all images in the current folder by typing

./labelimages

and they will come out like this:

You may need to install fonts, if so, see my post here.
