If you want or need a beginner-friendly introduction to programming concepts in JavaScript (on Jippity), check out my YouTube playlist recorded for that purpose:\nhttps://youtube.com/playlist?list=PLxxxPD9caN2RkhVFrjrDOnhsEubUTWjGC&si=7YWsfCfbPXtroLeq\n\nWe will proceed assuming you know the basics. I will still drop some reminders and you can always ask questions too! No question is too basic to ask.\n\nOur main focus today will be writing JavaScript code that powers up our HTML elements.\nWe made buttons, sliders, and menus last time. Let's have them actually do stuff now!\nA natural test playground is image manipulation. Let's upload and morph an image.\n*/\n\n//We create a constant (non-changing) variable in JS called imageUpload\n//that refers to the HTML element called 'imageUpload'\nconst imageUpload = document.getElementById('imageUpload');\n/*\nWe are going to call the method .addEventListener all the time.\nThe first argument, 'change', tells JS to do something whenever imageUpload changes — i.e. when someone clicks that button.\nThe second argument, handleImageUpload, is what we do when that change happens.\nhandleImageUpload is a *function* (basically a verb in JS) that we write below.\n*/\nimageUpload.addEventListener('change', handleImageUpload);\n\n//We create two more variables with 'let'. 'let' means we can change them later.\n//imageArray will be an array (a list) of images.\n//For now, it just has one default image which comes with this project.\n// Initially store the default image as an object with url and name\nlet imageArray = [{ url: \"@asset('jacobHead')\", name: \"Default Image\" }];\n//We refer to elements in an array with their *index*, which just means \"counter\".\n//Indices start at 0. The first image in our array has the index 0.\nlet currentImageIndex = 0;\n\n/*\nFunctions are actions that we program in JS.\nThe word 'function' lets you know that we're writing a function, then the next word is its name.\nThis function, handleImageUpload, takes in an event (whatever that is — we'll see!) and then does everything between { and }.\n*/\nfunction handleImageUpload(event) {\n //if the length of our array (the number of things on the list) is 5 or more,\n if (imageArray.length >= 5) {\n //*alert* ths user (like a pop-up) that they reached the max.\n alert(\"Maximum of 5 images reached.\");\n //then leave the function without doing anything else.\n return;\n }\n //On the other hand, if there is still space in the array, do all this.\n //This saves the first file the user uploads (we're expecting a picture).\n const file = event.target.files[0];\n //FileReader is a *class* that, well, reads files. It's built-in for us.\n const reader = new FileReader();\n //our FileReader will do this now:\n reader.onload = function (e) {\n //'push' means 'put this thing at the end of the list.\n imageArray.push({ url: e.target.result, name: file.name });\n //Update the index so the right option will appear in the menu\n currentImageIndex = imageArray.length - 1;\n //Then we call this function (written below) to update the menu.\n updateImageDropdown();\n //Then we call another function (written below as well) that loads the image.\n loadImageFromArray(imageArray.length - 1); //Why the minus one?\n //Lastly, reset all sliders.\n handleReset();\n }\n //We convert the file to a URL so that we can display it. HTML likes images as URLs.\n reader.readAsDataURL(file);\n\n}\n\n/*\nThis function assists the one above. \nRather than plop all this code into the earlier function, we pop it out into its own thing.\nThis is good practice. One function should complete one task and deal with one kind of data.\nThis function is about dropdown menus, while the earlier one is about loading images;\nDifferent tasks, different functions.\n*/\n\nfunction updateImageDropdown() {\n //Like before, we fetch an HTML element with document.getElementById\n const dropdown = document.getElementById('imageSelectDropdown');\n //Clear the existing options\n dropdown.innerHTML = '';\n //array.forEach *loops* code, one time for each element of the array.\n //index will change on each loop: 0, 1, 2, 3, 4.\n //We don't actually use imageSrc but that would also change to be the image data itself for each individual image.\n imageArray.forEach((imageSrc, index) => {\n //We create an option to put onto the menu\n const option = document.createElement('option');\n //We link it to the index to keep track of which is which\n option.value = index;\n //Set the text of the option using a helper function\n option.textContent = shortenFileName(imageSrc.name);\n //.appendChild says \"put this thing on that thing.\" The parent is the menu; the child is the individual option.\n dropdown.appendChild(option);\n });\n //Set dropdown selection to current image\n dropdown.value = currentImageIndex;\n\n}\n\n//Another function for another task: loading an image once it's been stored in our array.\nfunction loadImageFromArray(index) {\n //imageArray[index] points to the image with that index. imageArray[3] is the fourth image, for example.

We are careful up front to make sure nothing funky or unexpected happens.\n\nWith that out of the way, let's have some fun!\nThe goal is to *transform* an image with code and *control* those transformations with buttons, sliders, etc.\nThat opens a whole can of worms. From a computer's perspective, what is an image?\n(An array of pixels.) (What's a pixel?) \n((An array of colors.)) ((What's a color?))\n(((Oof. Slow down, cowboy.)))\n\nWe are not going to write an entire graphics processing library right now.\nThat's an amazing project to undertake, but not for the faint of heart.\nLuckily, many smart men and women have worked out the computations needed to display and transform graphics.\nSome of that is built into JavaScript and some we will recreate ourselves. \nEither way, you cannot just tell JS \"move this over here and turn it blue.\" You have to be more specific.\n(You can tell Jippity that and it will probably understand you. But it still helps to be as specific as possible.)\nWe are going to communicate with the computer in the universal language: mathematics.\nIn particular, we will use *numbers* and *geometry* to transform images.\n\nLet's dive in.\n*/\n\n\n//First, we make sure our JS is listening to the HTML elements: the sliders.\nconst translationSliderX = document.getElementById('translationSliderX');\nconst translationSliderY = document.getElementById('translationSliderY');\nconst rotationSlider = document.getElementById('rotationSlider');\nconst scaleSlider = document.getElementById('scaleSlider');\n\n//For each slider, call a function whenever the user does something.\ntranslationSliderX.addEventListener('input', handleTranslationX);\ntranslationSliderY.addEventListener('input', handleTranslationY);\nrotationSlider.addEventListener('input', handleRotation);\nscaleSlider.addEventListener('input', handleScale);\n\n//Now the real work: let's write the function that transform the image.\n\n/*\nThe basic idea behind computer graphics is that the screen is a *grid* of pixels.\nMy laptop screen has 5,939,136 pixels. That's a lot!\nEach pixel can be one of about a billion colors.\nThere are different ways to descibe colors to a computer. \nThe most common is RGB (red, green, blue) where each pixel is a mix of three primary colors.\nThe amount of R, G, B ranges from 0 to 255, so that (0, 0, 0) means no color at all (black), and (255, 255, 255) means \"shine the light of each color as bright as you can\" — that makes white.\nYou can, in theory, draw a picture on screen by specificying R, G, B for each individual pixel. \nBut that's a pain in the butt. We are going to zoom out a little from that and rely on code that other people have already written.\nBut underneath at all, don't forget about what's happening! Tiny little colored lights flashing at differing brightnesses. So simple, yet so powerful.\n*/\n\n\n//We set up two translation sliders: one in the horizontal (X) direction, and one in the vertical (Y) direction.\n//Let's initizalize the translation amounts in our first two *transformation variables*.\nlet translateX = 0;\nlet translateY = 0;\n\n//Same for rotation, but we just need one number (how much clockwise rotation)\nlet currentRotation = 0;\n\n//Scale will just be one number as well: a size multiplier\nlet currentScale = 1;\n\n//We'll also save a number that represents if the image is flipped or not. 1: not flipped; -1: flipped.\nlet flipState = 1;\n\n//When you touch a slider, it creates an 'event' and returns a number.\n//You can set the min and max number of a slider, as well as its step size, in HTML.\n\n//In each of the next four functions, we get the number that the slider returns and set our transformation variable to it.\n//Four transformation variables, four functions.\nfunction handleTranslationX(event) {\n translateX = parseInt(event.target.value);\n drawTransformedImage();\n}\n\n//spot the small difference?\nfunction handleTranslationY(event) {\n translateY = parseInt(event.target.value);\n drawTransformedImage();\n}\n\n//This slider is set up to return 0 through 360. Why?\nfunction handleRotation(event) {\n currentRotation = parseInt(event.target.value);\n drawTransformedImage();\n}\n\n//This one ranges from 0.1 to 2.9. Why? What happens if we change that range? \nfunction handleScale(event) {\n currentScale = parseFloat(event.target.value);\n drawTransformedImage();\n}\n\n//Finally, the main transformation function: the business end of our software weapon.\nfunction drawTransformedImage() {\n //A little setup to find the Canvas\n const canvas = document.getElementById('imageCanvas');\n const ctx = canvas.getContext('2d');\n //Prepare a blank Image type\n const img = new Image();\n //Then tell that Image to load in the current image we want\n img.src = imageArray[currentImageIndex].url;\n //Once the image is loaded, do all this:\n img.onload = function () {\n // Clear the canvas to prepare for the new drawing.\n ctx.clearRect(0, 0, canvas.width, canvas.height);\n\n // *Translate* (slide) the the view to the center of the canvas. (How does this work?)\n ctx.translate(canvas.width / 2, canvas.height / 2);\n\n // .scale makes an image bigger or smaller by multiplying its size (like stretching in the X and Y directions).\n //This line is just to handle flipping. flipState can either be -1 or 1, which represent flipping picture in the X direction or not.\n ctx.scale(flipState, 1);\n\n // If the image is flipped, we also flip the translateX slider's value. Why? \n let adjustedTranslateX = flipState === -1 ? -translateX : translateX;\n\n //We use the built-in .rotate method. Easy! We have to do a little math to convert from degrees to *radians*, which is the standard unit of angle rotation in math and physics.\n //(Don't sweat that detail unless you're interested, in which case, ask me.)\n //Why do we multiply by flipState here? What happens if we don't?\n ctx.rotate(flipState * currentRotation * Math.PI / 180);\n\n //Now the actual scaling -- sizing up and down. We have to apply the same number in both X and Y directions. What happens if we don't?\n ctx.scale(currentScale, currentScale);\n\n /* \n We are ready to draw the image.
