l do believe to have an issue regarding an if statement that allows for the detection of where the canvas object, being the image that displays , should be located at within the canvas. There is a reproducible demo provided.
NOTE: I do want to KEEP the css alignment, canvasauto, and not remove it if possible.
var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");
var the_button = document.getElementById("the_button");
var the_background = document.getElementById("the_background");
var imageXpos = 500;
var imageYpos = 300;
var imageWidth = 110;
var imageHeight = 80;
var imagecheck_Xpos = canvas.width - imageXpos;
var imagecheck_Ypos = canvas.height - imageYpos;
window.onload = function() {
ctx.drawImage(the_background, 0, 0, canvas.width, canvas.height);
ctx.drawImage(the_button, imagecheck_Xpos, imagecheck_Ypos, imageWidth, imageHeight);
}
the_button_function = (event) => {
const {
x,
y
} = event;
/* l believe the issue is here */
if ((x >= imagecheck_Xpos && x < (imagecheck_Xpos + imageWidth)) &&
(y >= imagecheck_Ypos && y < (imagecheck_Ypos + imageHeight))) {
alert("<Button>")
}
}
canvas.addEventListener('click', (e) => the_button_function(e));

You're using x from the MouseEvent. This is an experimental feature which is an alias of clientX.
The clientX property gives the coordinates relative to the application's viewport.
You probably want offsetX, which is relative to (the padding edge of the) target node.
var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");
var the_button = document.getElementById("the_button");
var the_background = document.getElementById("the_background");
var imageXpos = 500;
var imageYpos = 300;
var imageWidth = 110;
var imageHeight = 80;
var imagecheck_Xpos = canvas.width - imageXpos;
var imagecheck_Ypos = canvas.height - imageYpos;
window.onload = function() {
ctx.drawImage(the_background, 0, 0, canvas.width, canvas.height);
ctx.drawImage(the_button, imagecheck_Xpos, imagecheck_Ypos, imageWidth, imageHeight);
}
the_button_function = (event) => {
const {
offsetX: x,
offsetY: y
} = event;
/* l believe the issue is here */
if ((x >= imagecheck_Xpos && x < (imagecheck_Xpos + imageWidth)) &&
(y >= imagecheck_Ypos && y < (imagecheck_Ypos + imageHeight))) {
alert("<Button>")
}
}
canvas.addEventListener('click', (e) => the_button_function(e));

I have some Javascript drawing random square elements in the DOM. I have a gif (Image) I want these elements to appear over but they keep appearing underneath the gif. I tried defining z-depth and layout parameters to move these elements on top of the image here, but this produced no difference.
Any assistance in achieving the result (drawing elements onclick, on top of this gif) would be much appreciated.
I ultimately want to draw various other images over this image onclick, restricted to this particular area on top of the gif. If someone can suggest a solution to this as well I would be very much grateful!
(Code features some unused elements from my past attempts)

You have to use position:absolute; to take it out of the html flow.
Now anything added after the image will be placed like the image was never there.
img {
width: 100vw;
height: 100vh;
position: absolute;
top: 0;
left: 0;
z-index: -10;
}

I try to make drawing app on canvas. It works well in full screen but when I set its width and height according to a div container. It didn't work correctly. It starts painting from the right rather than the top left.
Here is my code pen link: https://codepen.io/pranaysharma995/pen/GRpGVmG.
div class="container">
<div class="col-md-4 col-md-offset-4 " id="canvas-container">
<canvas id="canvas">
</canvas></div>
#canvas-container{
position: relative;
width: 600px;
height: 600px;
background-color: #f3f6f7;
}
You have to offset the mouse position with the canvas.getBoundingClientRect
var canvas = document.querySelector("#canvas");
var container = document.querySelector(".col-md-4");
canvas.width = container.offsetWidth;
canvas.height = container.offsetHeight;
var c = canvas.getContext('2d');
c.fillStyle = "red";
c.strokeStyle = "red";
c.lineWidth = 5;
c.lineCap = "round";
function draw(e) {
var rect = canvas.getBoundingClientRect();
var x = e.clientX - rect.left
var y = e.clientY - rect.top
c.lineTo(x, y);
c.stroke();
}
canvas.addEventListener("mousemove", draw);
.container {
position: absolute;
left: 50px;
top: 25px
}
#canvas-container {
position: relative;
width: 200px;
height: 200px;
background-color: #f3f6f7;
}
<div class="container">
<div class="col-md-4 col-md-offset-4 " id="canvas-container">
<canvas id="canvas"></canvas>
</div>

I have 2 canvases side by side , and in the first one I have resizable draggable div as a crop region and I want to display the cropped region on the second canvas . But it is not happening in my case. Any help is appreciated
function crop(){
var x = $("#crop_square").width();
var y = $("#crop_square").height();
var ty = $("#crop_square").offset().top -
$("#area_c").offset().top;
var tx = $("#crop_square").offset().left -
$("#area_c").offset().left;
alert(x);
alert(y);
alert(ty);
alert(tx);
var c = document.getElementById("area_c"); //canvaas1
var c2 = document.getElementById("area_c2"); // canvas2
var ctx2 = c2.getContext("2d");
ctx2.drawImage(c,tx,ty,x,y,0,0,x,y );
}
If you need to "crop" a canvas with a div you may use the div's BoundingClientRect data to draw the image on the other canvas:
I hope this is what you were asking.
let cw = (area_c.width = area_c2.width = 400);
let ch = (area_c.height = area_c2.height = 400);
const ctx1 = area_c.getContext("2d");
const ctx2 = area_c2.getContext("2d");
theImg.onload = function() {
ctx1.drawImage(theImg, 0, 0);
let bcr = crop_square.getBoundingClientRect();
ctx2.drawImage(
theImg,
bcr.x,
bcr.y,
bcr.width,
bcr.height,
bcr.x,
bcr.y,
bcr.width,
bcr.height
);
}
.wrap {
width: 300px;
height: 300px;
border: 1px solid;
display: inline-block;
position: relative;
}
#crop_square {
position: absolute;
width: 150px;
height: 75px;
left: 100px;
top: 53px;
border: 5px solid gold;
}
<div class="wrap">

I just recently uploaded my code files to a server. My website is a simple html5 drawing application where users are able to draw freely. I have this part done fine, however I am looking to implement a download button that simply downloads whatever the user has drawn as an image directly to their device i.e. phone, table, desktop. I have been looking for solutions to this for hours now and cant find anything. Is it a problem with my server? or anything like that? any help would be much appreciated. Below is my code

You can use the Canvas#toDataURL method to generate a URL containing all the data of the canvas's current image. This can then be used in place of any URL -- a link's href, a window.open, etc. For a download link, you can use the download attribute on a link, which is an HTML5 addition. The value of the download attribute is the filename that will be used as the default save filename.
So to put all that together:
<a id='downloadLink' download='myDrawing.png'>Download Image</a>
<script>
function createDownload() {
const downloadURL = document.getElementById('c').toDataURL();
document.getElementById('downloadLink').href = downloadURL;
}
</script>
I looked for solutions to this problem for a long time, found some and I thought I understand but apparently I don't. I'd like to make a canvas that ppl can use to sign to confirm a booking. But I can't get the line to follow the user's cursor. My code looks like this:
HTML:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Signature Test</title>
<link rel="stylesheet" href="../css/test.css">
<script src="../js/jquery-3.2.0.js"></script>
</head>
<body>
<header id="header">
</header>
<section id="content">
<canvas id="signaturePad">DSorry your browser is rubbish</canvas>
</section>
<footer>
</footer>
<script src="../js/test.js"></script>
</body>
</html>
CSS:
body
{
margin: 0;
padding: 0;
}
header
{
border: 1px solid black;
width: 100%;
height: 50px;
}
#content
{
border: 1px solid blue;
width: 100%;
height: 300px;
position: relative;
}
#content #signaturePad
{
border: 1px solid red;
width: 200px;
height: 200px;
position: absolute;
left: calc(50% - 100px);
top: calc(50% - 100px);
}
footer
{
border: 1px solid black;
width: 100%;
height: 50px;
}
And finally the JS:
var canvas = document.getElementById("signaturePad");
var context = canvas.getContext("2d");
var radius = 1;
var dragging = false;
context.lineWidth = 2*radius;
