 1 | # Pixel Swap
 2 | 
 3 | Select an image. Select a color palette. Convert colors like magic. Try it here: [pixelswap.art](https://pixelswap.art).

 9 | ## Instructions
10 | 
11 | Pixel Swap is a small web application that swaps the colors of an image with the closest color from the selected palette. Here's how to use it:
12 | 
13 | 1. Select the color-matching method.
14 | 
15 | - Euclidean distance is the fastest. CIELAB is closest to how the human eye perceives differences in color in real life.
16 | - None of the methods take into account aesthetics or style, so often the "right" method for your conversion is a matter of personal choice.
17 | 
18 | 2. Select the image.
19 | 
20 | - Must be a .PNG file.
21 | - Alpha values won't be affected.
22 | - Large images will take longer to convert; performance is machine-dependent because the application runs client-side.
23 | - I would recommend images under 2000x2000px, but you can exceed this limit.
24 | 
25 | 3. Select the color palette.
26 | 
27 | - Must be a .GPL file ([GIMP Color Palette](https://docs.gimp.org/2.10/en/gimp-concepts-palettes.html)).
28 | - You can find a collection of color palettes here: https://lospec.com/palette-list. Download as GIMP .GPL.
29 | - There is minimal validation for color palettes. Please ensure the file you give the application is well-formatted.
30 | 
31 | 4. Download the image by clicking the converted picture or the "Download Result" button.
32 | 
33 | ## How
34 | 
35 | Pixel Swap converts an image's colors by comparing each pixel to every color in the selected palette. The color-by-color difference is calculated using the same method for every pixel in the image, but you can change the method to automatically recalculate the result. There are three possible methods:
36 | 
37 | 1. Euclidean Distance
38 | 
39 | - The difference between two colors is calculated by representing them as two points in 3D space, then calculating the distance between them [[1](#ref1)].
40 | - For both colors, let X = R, Y = G, and Z = B. Then, calculate the euclidean distance between the two resulting points. Shorter distances indicate smaller differences in color.
41 | 
42 | 2. Weighted RGB
43 | 
44 | - Identical to Euclidean Distance, except the individual difference in color is weighted differently for red, green, and blue.
45 | - I used 0.3 for red, 0.59 for green, and 0.11 for blue [[1](#ref1)].
46 | 
47 | 3. CIELAB
48 | 
49 | - The difference between two colors is equal to their difference in the CIE-L\*ab color space.
50 | - If the colors are represented in RGB, they must first be converted into the XYZ color format, and then into CIE-L\*ab [[2](#ref2)].
51 | - CIE-L\*ab color conversion depends on several constant reference values; my conversion is based on the D50 illuminant with a 2° (CIE 1931) observer because I read that they are commonly used.
52 | 
53 | Pixel Swap was originally written in JavaScript, then translated into C++ and compiled into WebAssembly to improve performance. To view the source code, visit the [app](./app/) folder.

 1 | ## Why WebAssembly?
 2 | 
 3 | Performance.
 4 | 
 5 | ## How?
 6 | 
 7 | By reading a lot of documentation, then replacing the core loop of my program with an optimized loop written in C++.
 8 | 
 9 | ```
10 | /* BEGIN WEBASSEMBLY CODE */
11 | 
12 | let pixelBuffer = Module._malloc(
13 |     pixels.length * Uint8Array.BYTES_PER_ELEMENT
14 | );
15 | Module.HEAPU8.set(pixels, pixelBuffer);
16 | Module.ccall(
17 |     "SwapColors",
18 |     null,
19 |     ["string", "array", "number", "number", "number"],
20 |     [ColorMatchingMethod, palette, palette.length, pixelBuffer, pixels.length]
21 | );
22 | 
23 | let convertedImage = new Uint8ClampedArray(
24 |     Module.HEAPU8.buffer,
25 |     pixelBuffer,
26 |     pixels.length
27 | );
28 | 
29 | Module._free(pixelBuffer);
30 | 
31 | /* END WEBASSEMBLY CODE */
32 | ```
33 | 
34 | The preceding code snippet is a great example of how to call an exported C++ method with a string, static array, integer, and dynamic array as parameters.
35 | 
36 | ## Gotcha's
37 | 
38 | When trying to hack this together, I encountered a couple of areas of confusion: scope, synchronization, and dynamic memory.
39 | 
40 | - Scope
41 |   - When I say scope, I'm referring to where my exported functions live and where I can call them.
42 |   - At a minimum, you need a .wasm file to run your compiled code in the browser.
43 |   - The easiest way to access and use this .wasm file is by importing the JavaScript glue file that's generated when compiling with [emscripten](https://emscripten.org/).
44 |   - The glue file will give you access to the "Module" object, which you can use to call functions exported from your C/C++ code such as malloc, free, and, in my case, the SwapColors method.
45 | - Synchronization
46 | 
47 |   - This is a small detail that I spent a lot longer on than I should have.
48 |   - Basically, I was trying to initialize the page by making a call to an exported method, but was getting undefined reference errors: `Uncaught TypeError: Cannot read properties of undefined (reading 'malloc') webassembly`.
49 |   - This error was occurring because the WebAssembly module hadn't fully loaded in, which confused me because it's the first script I import in "index.html."
50 |   - To fix the error, I simply wait until the Module has fully loaded before calling any exported methods (including malloc): `Module.onRuntimeInitialized = () => initializePreviewImages();`.
51 | 
52 | - Dynamic Memory
53 | 
54 |   - Code examples helped me out tremendously with this one.
55 |   - To call methods that require dynamically allocated memory, you must use the HEAP found on the WebAssembly Module.
56 |   - You can write to the HEAP using the "set" method and read from it by accessing the buffer (i.e. Module.HEAP.buffer) [[1](#ref1)].
57 | 
58 | ## A Note On Compilation
59 | 
60 | emscripten offers [many compiler settings](https://github.com/emscripten-core/emscripten/blob/main/src/settings.js). I would recommend sticking to what's necessary while making sure to include the optimization flag (use -O3 for the best performance). My final compiler command came out to:
61 | 
62 | ```
63 | emcc src/Main.cpp src/Color.cpp -o build/pixel-swap.js -O3 -sALLOW_MEMORY_GROWTH=1 -sEXPORTED_RUNTIME_METHODS=ccall -sEXPORTED_FUNCTIONS=_main,_SwapColors,_free
64 | ```
65 | 
66 | - At first, I was using `-sLINKABLE=1` and `-sEXPORT_ALL=1` to resolve undefined symbol errors, but this resulted in a bloated output file and Module object.
67 | - `-sALLOW_MEMORY_GROWTH=1` was necessary to store larger images (exceeding a few megabytes) on the heap.
68 | - I didn't include "cwrap" in `EXPORTED_RUNTIME_METHODS` because I didn't use it, but in other examples, you will see them include both.
69 | - The .js on the end of `-o build/pixel-swap.js` tells emscripten to build only the .wasm and .js glue file. You can also build a .html file, but I didn't because I wasn't going to use it.
70 | - `-O3` is the highest level of optimization you can specify for the compiler and I would recommend including this in your production code otherwise you aren't fully taking advantage of the power of WebAssembly.
