Pixel Art in Patterning
"Pixel art" images are low resolution, made with coloured blocks.
We now have the pixel function in Patterning to help make these images.
pixel takes three arguments. The width/height of the grid in pixels. (All pixel grids are square). A vector of numbers representing the colour of each pixel. And a map from those numbers to a colour.
