picasa from command line

mkrems · 04-04-2009, 02:02 PM

hi there, i was wanting to use picasa (using the export function) to watermark my photos but it is really annoying to do in the gui. all repetitive tasks naturally want to be scripted. does anyone know how to do this? basically i want to be able to tell what year the image was taken and then watermark all my photos automatically. thanks!

No idea about how to do it in picassa but if I wanted to do what you want to do, I'd use ImageMagick. Specifically http://www.imagemagick.org/Usage/annotating/
It's probably already installed on your machine, if not check the repos and it'll be there.

Though I have the feeling there ought to be a much better way to do that but can't just figure one out right now.

Code:

for i in *.jpg;do
   year=$(ls --full-time ${i} | awk '{print $6}' | cut -d - -f 1)
   see_linked_examples_for_a_convert_command_to_use_here_you_can_use_the_variable_year_in_the_text
done

I have a feeling there should be a much better way to get the year a file was modified than the example above.

Thanks for the info. Although I like picasa for the watermark because it automatically decides whether the font should be white or black based on the surrounding color in the image which is nice. Do you know if it is even possible to use Picasa from the command line?

I don't know. If it is I'm sure the functionality will documented on Google's website.
Though Picasa for Linux is not a native Linux app, it runs under a bundled version of Wine, which makes me doubt it has any sort of significant commandline options. I could be wrong though.
