We're still missing optional argument support, so this implementation
doesn't support fill(), only fill(fill_rule).
Still it's really nice to get rid of so much hand-written wrapper code.
This implements only one of the two forms of this function,
ctx.fill(winding_rule).
Also tweaks the quadratic curve demo to have a nice looking filled
shape.
This patch adds the following methods to CanvasRenderingContext2D:
- beginPath()
- moveTo(x, y)
- lineTo(x, y)
- closePath()
- stroke()
We also add the lineWidth property. :^)
We will no longer create bitmap buffers for canvases that exceed a
total area of (16384 * 16384) pixels. This matches what some other
browser do.
Thanks to @itamar8910 for finding this! :^)
Add an implementation of CanvasRenderingContext2DWrapper.strokeRect().
While implementing this I fixed fillRect() and the new strokeRect() to
honor the .scale() and .translate() values that had previously been plumbed.
Also enhance the canvas.html demo to utilize strokeRect(), scale(), and translate().
We now support rAF, driven by GUI::DisplayLink callbacks. It's a bit
strange how we keep registering new callbacks over and over.
That's something we can definitely optimize.
This allows you to update animations/whatever without doing it more
often than the browser can display.
This patch adds HTMLCanvasElement along with a LayoutCanvas object.
The DOM and layout parts are very similar to <img> elements.
The <canvas> element holds a Gfx::Bitmap which is sized according to
the "width" and "height" attributes on the element.
Calling .getContext("2d") on a <canvas> element gives you a context
object that draws into the underlying Gfx::Bitmap of the <canvas>.
The context weakly points to the <canvas> which allows it to outlive
the canvas element if needed.
This is really quite cool. :^)
