#PALETTE SWAP TOOL IN MC PAINT CODE#

It turns out the code is just about as simple, with most of the length going into loading and saving the images and format juggling.įirst, we want a way of representing pixels which in this context are a color and a location: For each pair of pixels in the two lists, take the color from the target image and the location from the source imageĪnd that’s actually it.

Sort the two lists by a given comparator.

Create a list of pixels from each image.

The first algorithm sounds crazy until you try it.

Swap pixels until the image is ‘close enough’.

There are a bunch of different ways to solve this, but today we’ll go through three of them: Specifically for this post, we’ll be using two source images, although for testing I had a whole pile more: Mona Lisa by Leonardo da Vinci, c. – American Gothic in the palette of Mona Lisa: Rearrange the pixels The copy must have the same dimensions as the Source. Each pixel in the Palette must be used exactly once in a unique position in this copy. Your task is to create an algorithm that makes the most accurate looking copy of the Source by only using the pixels in the Palette. They do not necessarily have the same dimensions but it is guaranteed that their areas are the same, i.e. You are given two true color images, the Source and the Palette. Luckily, the same StackExchange also host popularity contests, one of which is the inspiration behind today’s post:

The idea behind code golf is to write a program with as few characters as possible, often rendering the code nigh on unreadable.

Today’s task comes from the Code Golf StackExchange.
