Compiling an Existing C Module to WebAssembly - WebAssembly
looking at the encoding api of libwebp, you'll find that it expects an array of bytes in rgb, rgba, bgr or bgra.
... luckily, the canvas api has canvasrenderingcontext2d.getimagedata — that gives you an uint8clampedarray containing the image data in rgba: async function loadimage(src) { // load image const imgblob = await fetch(src).then(resp => resp.blob()); const img = await createimagebitmap(imgblob); // make canvas same size as image const canvas = document.createelement('canvas'); canvas.width = img.width; canvas.height = img.height; // draw image onto canvas const ctx = canvas.getcontext('2d'); ctx.drawimage(img, 0, 0); return ctx.getimagedata(0, 0, img.width, img.height); } now it's "only" a matter of copying the data from javascript into wasm.
...ons — one that allocates memory for the image inside wasm and one that frees it up again: #include <stdlib.h> // required for malloc definition emscripten_keepalive uint8_t* create_buffer(int width, int height) { return malloc(width * height * 4 * sizeof(uint8_t)); } emscripten_keepalive void destroy_buffer(uint8_t* p) { free(p); } the create_buffer() function allocates a buffer for the rgba image — hence 4 bytes per pixel.

GLSL Shaders - Game development
fragment shaders fragment (or texture) shaders define rgba (red, blue, green, alpha) colors for each pixel being processed — a single fragment shader is called once per pixel.
... the calculations result in a variable containing the information about the rgba color.
... the texture shader code now we'll add the texture shader to the code — add the code below to the body's second <script> tag: void main() { gl_fragcolor = vec4(0.0, 0.58, 0.86, 1.0); } this will set an rgba color to recreate the current light blue one — the first three float values (ranging from 0.0 to 1.0) represent the red, green, and blue channels while the fourth one is the alpha transparency (ranging from 0.0 — fully transparent — to 1.0 — fully opaque).

this is because, just as with css, color can be specified as a hexadecimal value, a color keyword, the rgba() function, or any of the other available color methods.
...try adding this code to your javascript too: ctx.beginpath(); ctx.rect(160, 10, 100, 40); ctx.strokestyle = "rgba(0, 0, 255, 0.5)"; ctx.stroke(); ctx.closepath(); the code above prints a blue-stroked empty rectangle.
... thanks to the alpha channel in the rgba() function, the blue color is semi transparent.

Styling tables - Learn web development
start by adding the following css to your style.css file, again at the bottom: /* graphics and colors */ thead, tfoot { background: url(leopardskin.jpg); color: white; text-shadow: 1px 1px 1px black; } thead th, tfoot th, tfoot td { background: linear-gradient(to bottom, rgba(0,0,0,0.1), rgba(0,0,0,0.5)); border: 3px solid purple; } again, there's nothing specific to tables here, but it is worthwhile to note a few things.

Normal Flow - Learn web development
overflowing inline elements will <span>wrap onto a new line if possible (like this one containing text)</span>, or just go on to a new line if not, much like this image will do: <img src="https://udn.realityripple.com/samples/9e/6ff6af6fd4.jpg"></p> body { width: 500px; margin: 0 auto; } p { background: rgba(255,84,104,0.3); border: 2px solid rgb(255,84,104); padding: 10px; margin: 10px; } span { background: white; border: 1px solid black; } summary now that you understand normal flow, and how the browser lays things out by default, move on to understand how to change this default display to create the layout needed by your design.

Positioning - Learn web development
ut id ornare felis, eget fermentum sapien.</p> body { width: 500px; margin: 0 auto; } .positioned { background: rgba(255,84,104,.3); border: 2px solid rgb(255,84,104); padding: 10px; margin: 10px; border-radius: 5px; } .positioned { position: sticky; top: 30px; left: 30px; } an interesting and common use of position: sticky is to create a scrolling index page where different headings stick to the top of the page as they reach it.

How CSS is structured - Learn web development
write css rules that apply styling to different html elements: transform background-image, in particular gradient values color, in particular rgb/rgba/hsl/hsla values @rules css @rules (pronounced "at-rules") provide instruction for what css should perform or how it should behave.

Styling web forms - Learn web development
textarea { font : 1.4em/1.5em "handwriting", cursive, sans-serif; border : none; padding : 0 10px; margin : 0; width : 80%; background : none; } when one of these fields gains focus, we highlight them with a light grey, transparent, background (it is always important to have focus style, for usability and keyboard accessibility): input:focus, textarea:focus { background : rgba(0,0,0,.1); border-radius: 5px; } now that our text fields are complete, we need to adjust the display of the single and multiple line text fields to match, since they won't typically look the same using the defaults.

Functions — reusable blocks of code - Learn web development
in our random-canvas-circles.html example (see also the full source code) from our loops article, we included a custom draw() function that looked like this: function draw() { ctx.clearrect(0,0,width,height); for (let i = 0; i < 100; i++) { ctx.beginpath(); ctx.fillstyle = 'rgba(255,0,0,0.5)'; ctx.arc(random(width), random(height), random(50), 0, 2 * math.pi); ctx.fill(); } } this function draws 100 random circles inside a <canvas> element.

Function return values - Learn web development
our draw() function draws 100 random circles somewhere on an html <canvas>: function draw() { ctx.clearrect(0, 0, width, height); for (let i = 0; i < 100; i++) { ctx.beginpath(); ctx.fillstyle = 'rgba(255,0,0,0.5)'; ctx.arc(random(width), random(height), random(50), 0, 2 * math.pi); ctx.fill(); } } inside each loop iteration, three calls are made to the random() function, to generate a random value for the current circle's x-coordinate, y-coordinate, and radius, respectively.

Video and Audio APIs - Learn web development
last but not least, let's look at the css for the timer: .timer { line-height: 38px; font-size: 10px; font-family: monospace; text-shadow: 1px 1px 0px black; color: white; flex: 5; position: relative; } .timer div { position: absolute; background-color: rgba(255,255,255,0.2); left: 0; top: 0; width: 0; height: 38px; z-index: 2; } .timer span { position: absolute; z-index: 3; left: 19px; } we set the outer .timer <div> to have flex: 5, so it takes up most of the width of the controls bar.

What is JavaScript? - Learn web development
we can mark it up using html to give it structure and purpose: <p>player 1: chris</p> then we can add some css into the mix to get it looking nice: p { font-family: 'helvetica neue', helvetica, sans-serif; letter-spacing: 1px; text-transform: uppercase; text-align: center; border: 2px solid rgba(0,0,200,0.6); background: rgba(0,0,200,0.3); color: rgba(0,0,200,0.6); box-shadow: 1px 1px 2px rgba(0,0,200,0.4); border-radius: 10px; padding: 3px 10px; display: inline-block; cursor: pointer; } and finally, we can add some javascript to implement dynamic behaviour: const para = document.queryselector('p'); para.addeventlistener('click', updatename); function updatename() { ...

constants the following constants can be used for srcrgb, dstrgb, srcalpha, and dstalpha the formulas for the blending factors can be described like this (all rgba values are between 0 and 1): color(rgb) = (sourcecolor * srcrgb) + (destinationcolor * dstrgb) color(a) = (sourcealpha * srcalpha) + (destinationalpha * dstalpha) constant rgb factor alpha factor description gl.zero 0,0,0 0 multiplies all colors by 0.

a pixel is a picture element (in practice, a point) on the screen, or a single element of the drawing buffer, that area in memory that holds your pixel data (such as rgba color components).

Clearing with colors - Web APIs
finally, we note that color in webgl is usually in rgba format, that is four numerical components for red, green, blue and alpha (opacity).
