So I have looked all over this forum/stackoverflow/etc and the best IM halftone filter I found was this one:
The main issue being that it isn't using dots with varying sizes. Then I found this:
Which is open source but done in WebGL, which seems to be done using screens with varying dot sizes, but without the varying angles of screens. The code for it:

https://github.com/evanw/glfx.js/blob/m ... /shader.js
It seems like if we could use this screen but with the correct angles this would be a true halftone filter. How would this be implemented in an IM command?
