Accessing Viewport State
The read-only viewport transform state can be accessed via the viewport property of the canvas.
const element = document.getElementById('canvas');
const canvas = new CanvasBuilder(element)
.build();
console.log(canvas.viewport);
The viewport object provides two methods:
get the state of the viewport matrix
const viewportMatrix = canvas.viewport.getViewportMatrix();get the state of the content matrix
const contentMatrix = canvas.viewport.getContentMatrix();
