Shell Programming and Scripting

Greetings.

I've come across a bit of a problem with notify-send syntax; and wondered if anyone out there had found a solution in the woodpile somewhere

Here's the snippet which is giving me trouble:

Code:

notify-send 'Text to display' image_data 300, 300, , , , , /etc/image.png

Output:

Code:

Invalid number of options.

Of course the -i switch works well, but there's no way of specifying image size parameters. I know I'm probably missing the boat by something simple here, but the manpage seems a bit cursory in the matter; so I hit an impasse...

In short, what might a properly-formed commandline/bash block look like to make this work?

Thanks; and have a great day!
