+ <p>You can use several context attributes when creating your rendering context, for example:</p>
+
+ <pre class="brush: js">offscreen.getContext("webgl",
+                 { antialias: false,
+                   depth: false });</pre>
+ 2d context attributes:
+
+ <ul>
+  <li><strong><code>alpha</code></strong>: Boolean that indicates if the canvas contains an alpha channel. If set to <code>false</code>, the browser now knows that the backdrop is always opaque, which can speed up drawing of transparent content and images then.</li>
+  <li>{{non-standard_inline}} (Gecko only) <strong><code>willReadFrequently</code></strong>: Boolean that indicates whether or not a lot of read-back operations are planned. This will force the use of a software (instead of hardware accelerated) 2D canvas and can save memory when calling {{domxref("CanvasRenderingContext2D.getImageData", "getImageData()")}} frequently. This option is only available, if the flag <code>gfx.canvas.willReadFrequently.enable</code> is set to <code>true</code> (which, by default, is only the case for B2G/Firefox OS).</li>
+  <li>{{non-standard_inline}} (Blink only) <strong><code>storage</code></strong>: String that indicates which storage is used ("persistent" by default).</li>
+ </ul>
+ WebGL context attributes:
+
+ <ul>
+  <li><strong><code>alpha</code></strong>: Boolean that indicates if the canvas contains an alpha buffer.</li>
+  <li><strong><code>depth</code></strong>: Boolean that indicates that the drawing buffer has a depth buffer of at least 16 bits.</li>
+  <li><strong><code>stencil</code></strong>: Boolean that indicates that the drawing buffer has a stencil buffer of at least 8 bits.</li>
+  <li><strong><code>antialias</code></strong>: Boolean that indicates whether or not to perform anti-aliasing.</li>
+  <li><strong><code>premultipliedAlpha</code></strong>: Boolean that indicates that the page compositor will assume the drawing buffer contains colors with pre-multiplied alpha.</li>
+  <li><strong><code>preserveDrawingBuffer</code></strong>: If the value is true the buffers will not be cleared and will preserve their values until cleared or overwritten by the author.</li>
+  <li>
+   <p><code><strong>failIfMajorPerformanceCaveat</strong></code>: Boolean that indicates if a context will be created if the system performance is low.</p>

+<h3 id="OffscreenCanvas_에서_만들어진_프레임을_동기적으로_화면에_보여주는_방법"><code>OffscreenCanvas</code> 에서 만들어진 프레임을 동기적으로 화면에 보여주는 방법</h3>
+
+<p><code>OffscreenCanvas</code> API를 사용하는 방법은 <code>OffscreenCanvas</code>에 속한 {{domxref("RenderingContext")}}를 이용해 새로운 프레임 객체를 생성하는 것입니다. 새 프레임이 컨텍스트에 렌더링이 되고나면, 가장 최근에 렌더링 된 이미지를 저장하는 {{domxref("OffscreenCanvas.transferToImageBitmap", "transferToImageBitmap()")}} 메소드를 호출할 수 있습니다. 이 메소드는 다른 수 많은 Web API에서 사용되고 있는 {{domxref("ImageBitmap")}} 객체를 리턴합니다.</p>
+
+<p><code>ImageBitmap</code>을 화면에 표시하려면, 현재 (화면에 보여지고 있는) 캔버스 요소의 <code>canvas.getContext("bitmaprenderer")</code> 메소드를 호출했을 때 생성되는 {{domxref("ImageBitmapRenderingContext")}} 객체를 사용하면 됩니다. 이 컨텍스트는 캔버스의 내용을 주어진 <code>ImageBitmap</code>으로 전환하는 기능을 제공합니다.  OffscreenCanvas에서 이전에 렌더링이 되어서 등록된 <code>ImageBitmap</code>을 이용한 {{domxref("ImageBitmapRenderingContext.transferFromImageBitmap()")}}을 호출하면 <code>ImageBitmap</code>이 캔버스에 표시되고 소유권 역시 캔버스로 넘어갑니다. 단일 <code>OffscreenCanvas</code>는 프레임들을 임의의 다른 <code>ImageBitmapRenderingContext</code> 객체로 전달합니다.</p>
+
+<p>아래에 두 개의 {{HTMLElement("canvas")}} 요소가 있습니다.</p>
+
+<pre class="brush: html">&lt;canvas id="one"&gt;&lt;/canvas&gt;
+&lt;canvas id="two"&gt;&lt;/canvas&gt;</pre>
+
+<p>다음의 코드는 위에서 설명한 것처럼 <code>OffscreenCanvas</code>를 이용해 렌더링합니다.</p>
+
+<pre class="brush: js">var one = document.getElementById("one").getContext("bitmaprenderer");
+var two = document.getElementById("two").getContext("bitmaprenderer");
+
+var offscreen = new OffscreenCanvas(256, 256);
+var gl = offscreen.getContext('webgl');
+
+// ... gl 컨텍스트를 이용해 첫 번째 캔버스에 무언가를 그립니다 ...
+
+// 첫 번째 캔버스에 렌더링을 수행합니다.
+var bitmapOne = offscreen.transferToImageBitmap();
+one.transferFromImageBitmap(bitmapOne);
+
+// ... gl 컨텍스트를 이용해 두 번째 캔버스에 무언가를 그립니다 ...
+
+// 두 번째 캔버스에 렌더링을 수행합니다.
+var bitmapTwo = offscreen.transferToImageBitmap();
+two.transferFromImageBitmap(bitmapTwo);

+
+<p><code>OffscreenCanvas</code> API를 이용하는 또 다른 방법은  <a href="/en-US/docs/Web/API/Web_Workers_API">worker</a> 또는 메인 스레드위에서 {{HTMLElement("canvas")}} 요소의 {{domxref("HTMLCanvasElement.transferControlToOffscreen", "transferControlToOffscreen()")}}를 호출하는 것입니다. 여기서 메인 스레드는 <code>OffscreenCanvas</code> 객체를 반환하는 {{domxref("HTMLCanvasElement")}} 객체를 가지고 있습니다. {{domxref("OffscreenCanvas.getContext", "getContext()")}}를 호출하면 <code>OffscreenCanvas</code>에서 <code>RenderingContext</code>를 얻을 수 있습니다.</p>
