Hello again,
I already saw that there is a command line tool, but can I retrieve all the
information with it? Like the color of the note?
In the meantime I already figured out that I have to use NSKeyedUnarchiver to
get the 'real' data - and it worked!
Now what I get in return is an NSArray, which is now 'human-readable'. Below
there is an example element of that array.
Question: I would like to have some sort of RGB-Value like used to denote
colors in HTML webpages. I don't quite know what 'NSDeviceRGBColorSpace 0
0.976805 0 1' nor to translate it into some sort of RGB(x, y, z) value. Do you
have an idea?
