Turn a picture into strokes with varied thickness.

edited January 2016 in How To...

Hello, guys :)

I've been learning processing for fun over the past few months and decided to go for the next step: create some sort of tool I could convert images into something similar to these Karel Martens posters.

After trying it a bit I would like to get some advice from you, specially in terms of what direction would be best to follow. I'm starting my sketch by converting the pixels in a black and white picture into an array. Then I would like to use this array to determine the thickness of the vertical lines. However, I'm still not sure this is the best way to go and what to do next.

Thanks for your help!

    I would

    • load the image
    • then resize it to fit the number of rows and columns of your grid.
    • loop over the pixels-array
    • check the brightness of each pixel
    • and draw rectangles with different width or height depending on the brightness

    cut the image in small but wide horizontal sub-images

    place them with a small y-offset on a new white cavas
