drawImageScaled method
- @JSName('drawImage')
- CanvasImageSource source,
- num destX,
- num destY,
- num destWidth,
- num destHeight,
Draws an image from a CanvasImageSource to an area of this canvas.
The image will be drawn to this context with its top left corner at the
point (destX, destY) and will be scaled to be destWidth wide and
destHeight tall.
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');
img.width = 100;
img.height = 100;
// Scale the image to 300x50 at the point (20, 20)
ctx.drawImageScaled(img, 20, 20, 300, 50);
