The easiest way to do what you want is too rely on Paper.js
built-in resize handling:
- add
resize
attribute to your<canvas>
(see "Canvas Configuration" part in the documentation) - setup an event handler callback as view.onResize value, to update your project accordingly to the new view size
// setup paper
paper.setup('canvas');
// draw a circle at view center
var circle = new paper.Path.Circle({
center: paper.view.center,
radius: 50,
fillColor: 'orange'
});
// when view is resized...
paper.view.onResize = function() {
// ...log new view width
console.log('view.width is now: ' + paper.view.bounds.width);
// ...place circle at new view center
circle.position = paper.view.center;
};
// draw instructions
new paper.PointText({
content: 'Resize the window and see that view is automatically resized',
point: paper.view.center.subtract(0, 80),
justification: 'center'
});
html,
body {
margin: 0;
overflow: hidden;
height: 100%;
}
/* Scale canvas with resize attribute to full size */
canvas[resize] {
width: 100%;
height: 100%;
}

The easiest way to do what you want is too rely on Paper.js

// setup paper

// draw a circle at view center

});
// when view is resized...
paper.view.onResize = function() {
// ...log new view width
console.log('view.width is now: ' + paper.view.bounds.width);
// ...place circle at new view center
circle.position = paper.view.center;
};
// draw instructions
new paper.PointText({
content: 'Resize the window and see that view is automatically resized',
point: paper.view.center.subtract(0, 80),
justification: 'center'
});
html,
body {
margin: 0;
overflow: hidden;

/* Scale canvas with resize attribute to full size */
canvas[resize] {
width: 100%;
