One fine day i decided i want “watermark” on my photos too, i know am not a great photographer but just for sake i wanted one.
I am too lazy to do anything from GUI so i searched a bit and came to know about ImageMagic and mogrify.
I simply installed it on my ubuntu box :-
sudo apt-get install imagemagik
Once i had it installed i decided using same watermark for all my images which which were lying in my directory at Desktop with name “foto”
One of the photos before watermark
I simply used the command :-
$ mogrify -font /usr/share/fonts/truetype/freefont/FreeSerifBoldItalic.ttf -pointsize 100 -verbose -draw "fill red text 24,75 '@koolhead17' " /home/atul/Desktop/foto/*.jpg
i am selecting a font, asking for verbose, drawing, filling it with red color text with mentioned size.
This is how it looks after watermark :-
I would highly recommend any one who is lazy as i am to give a try to imagemagik.
