As much as I appreciate that the image is not being stored in 1-bit format, this isnt necessary for what I'm doing. Thanks for the help though.

Thanks! This is exactly what I wanted

I am trying to create an image which is in purely black and white, no shades of grey; How do I do this? My ideas are: - Make the rendering resolution of the document equal to the output resolution (1x) (disable antialiasing) -- Ideal solution - Reduce the colour space to just black and white - Some export option I haven't thought of I have also tried the palettised export setting but that produces a lot of artefacts (below)

Thanks to everyone for your help and sorry for the late reply! @v_kyr Thanks for all the link! I've found some good patterns from there that I'll bookmark and one that will probably work for this with some tweaking. @GarryP The mathematica solution sounds like it can be very effective if I can get that working. @h_d It's a shame we can't add scripts. Sounds like someon should make a feature request. @John Rostron I don't get what you mean? What software are you referring to? Thanks again!

So I want to make a random triangular pattern in photo but so far I haven't found an efficient way of going it. My target is something similar to the below image but the colours are randomly selected within a range. If possible I would also like the overall colour gradient to get darker down the page. (I know this is more of a designer job but I don't have this software at current and I can't find a way to do it in there either) So far I have found that I can create a triangular grid using induvidual triangle shapes made with the pen tool that I've replicated using a horizontal triangular grid (see below) as a guide. I could colour them manually but this would be far too slow. Thanks for any help!
