<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
</canvas>

Answer №1

If you want to display the image as a background, make sure to adjust the size using background-size property.

var picture = new Image();
picture.src = 'http://www.ziiweb.com/images/logo.png';

$('canvas').css({
    backgroundImage: 'url(' + picture.src + ')',
    backgroundSize: "100%"
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
</canvas>

Answer №2

When incorporating images into your website, remember to utilize an img tag that can be customized in size using CSS. Alternatively, if you opt for the background property, ensure to apply "background-size: cover;" for a seamless fit. To stretch the image unevenly, specify the dimensions with "background-size: 200px 300px;".

Answer №3

Give this a shot

Adjust the width of the image to 200 pixels.

Answer №4

Experimenting with CSS background attributes:

let pic = new Image();
pic.src = 'http://www.ziiweb.com/images/logo.png';
$('canvas').css({
    background: 'url(' + pic.src + ') no-repeat 0% 50%',
    backgroundSize: '100%',
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
</canvas>

no-repeat, 0% 50% will position the image vertically centered and make it fit the canvas's width.
