We create a lot of B/W images, and now we are thinking about plotter-costs (usage of printer-toner or plotter-ink). I would like to make an analysis of our existing images:
-> How many pixels has the image in total?
-> How many pixels are black?
(-> How many pixels are coloured? -> For 1% of the images which are not BW)

-->> What is the percentage of black/white pixels?

Any easy(!!) ideas?

Regards

Peter

Or with something else ...(Freeware)

If possible a command-line tool for batch-commands.

"Analyse and Report" would be a fine new feature for XnConvert, wouldn`t it?
