[Gimp-user] howto obtain level information

[Jan Wuerthner]

hello,

I am looking for a way to write something similar to the plug_in_normalize 
function by scripting: For some reason the normalize function doesn't stretch 
the levels the way I expect, often there is still a large area of unused color 
values (I assume there may be very small values not shown in the histogram).

Anyway, I have seen there is a function gimp_levels I can use to set the 
values. Now I need something like gimp_get_levels to determine the values I 
want to set. I haven't found anything to get the levels information from a 
drawable. Can anyone help me?

Thank you, kind regards
Jan Würthner

The PDB function gimp-histogram is that which you seek.
