drawImage method
- CanvasImageSource source,
- num destX,
- num destY
Draws an image from a CanvasImageSource to this canvas.
The entire image from source
will be drawn to this context with its top
left corner at the point (destX
, destY
). If the image is
larger than canvas will allow, the image will be clipped to fit the
available space.
CanvasElement canvas = new CanvasElement(width: 600, height: 600);
CanvasRenderingContext2D ctx = canvas.context2D;
ImageElement img = document.query('img');
ctx.drawImage(img, 100, 100);
VideoElement video = document.query('video');
ctx.drawImage(video, 0, 0);
CanvasElement otherCanvas = document.query('canvas');
otherCanvas.width = 100;
otherCanvas.height = 100;
ctx.drawImage(otherCanvas, 590, 590); // will get clipped
