 For this week's Circuit Python Parsec, I wanted to show you a little trick you can do with swapping out colors in an image palette using Display.io. I'm just using the Iterford image load to load this BMP image up on screen. But the trick, the thing I wanted to show you here, I'm going to uncomment my code and resave it to the board. And now what you're going to see is it's going to go through and one by one replace each color in the palette with green. You can pick any color you want, you can do more sophisticated things. But here what you'll see is just every time it loops through, it's going to display the original image for a second and then it's going to start just making its way through the palette and switch the palette value for green. If I change this out we can do something like, let's say red, it's not quite as visible actually because this starts out as an orange image. But you can see there one by one each of those colors changing and this is a really neat trick. It's something that has its roots in video game art using palettes to swap how things look so that you don't have as many big heavy assets in your scene was a common trick. Take a look at the code here. We're doing an image load, we're setting up some Display.io stuff and then this function here image and palette are cast into this Iterford image load load and then the name of your BMP image sets up the bitmap as a tile grid image using a pixel shader based on the palette and then in the main loop what I'm doing is grabbing that palette and then one by one I go through however many colors are in the palette and I'm saying take each one starting on the first one and replace it with whatever color I've picked. So if we go in here and change this to blue let's say. So now what you'll see is it just goes through one at a time changes it takes a little a moment there and then it holds that image for a second and repeats it. So that is how you can replace the colors in an image with a specific color using Display.io's palette shaders and that is your circuit Python Parsec.
