canvasDrawRect
$canvasDrawRect[]
When fill is false, the rectangle is drawn as a 1-pixel wide outline — there is no thickness parameter. For thicker outlines, use multiple overlapping rectangles or $canvasDrawLine calls. For rectangles with rounded corners, prefer $canvasDrawRoundedRect. The blend mode enables per-pixel compositing for effects like shadows and overlays.
