+<p>Das <strong><code>HTMLCanvasElement</code></strong> interface bietet Eigenschaften und Methoden zum Manipulieren des Layouts und der Darstellung des <code>&lt;canvas&gt;</code>-Elements. Das <code>HTMLCanvasElement</code> interface erbt außerdem Eigenschaften und Methoden des {{domxref("HTMLElement")}} interface.</p>

+<dl>
+ <dt>{{domxref("HTMLCanvasElement.height")}}</dt>
+ <dd>Ein positiver <code>integer</code>, der das {{htmlattrxref("height", "canvas")}} HTML-Attribut des {{HTMLElement("canvas")}} Elements in CSS-Pixeln repräsentiert. Wenn nicht definiert oder wenn es auf einen nicht erlaubten Wert (z.B. einen negativen Wert) gesetzt wird, wird der Standardwert <strong>150</strong> verwendet.</dd>
+ <dt>{{domxref("HTMLCanvasElement.mozOpaque")}} {{non-standard_inline}}</dt>
+ <dd>Ein {{jsxref("Boolean")}}, der das {{htmlattrxref("moz-opaque", "canvas")}} HTML-Attribut des {{HTMLElement("canvas")}} Elements repräsentiert. Es sagt dem canvas, ob auf Transparenz verzichtet werden soll. Falls <code>true</code>, kann das Zeichnen auf dem canvas beschleunigt werden.</dd>
+ <dt>{{domxref("HTMLCanvasElement.width")}}</dt>
+ <dd>Ein positiver <code>integer</code>, der das {{htmlattrxref("width", "canvas")}} HTML-Attribut des {{HTMLElement("canvas")}} Elements in CSS-Pixeln anzeigt. Wenn nicht definiert oder wenn es auf einen nicht erlaubten Wert (z.B. einen negativen Wert) gesetzt wird, wird der Standardwert <strong>300</strong> verwendet.</dd>

+<p><em>Erbt Eigenschaften von seinem Elternelement, </em><em>{{domxref("HTMLElement")}}.</em></p>
+
+<dl>
+ <dt>{{domxref("HTMLCanvasElement.captureStream()")}} {{experimental_inline}}</dt>
+ <dd>Gibt ein {{domxref("CanvasCaptureMediaStream")}} zurück, dieses ist ein Echtzeit-Video der Oberfläche des canvas.</dd>
+ <dt>{{domxref("HTMLCanvasElement.getContext()")}}</dt>
+ <dd>Gibt einen context des canvas zurück oder <code>null</code>, falls die context-ID nicht unterstützt wird. Ein context ermöglicht es, auf dem canvas zu zeichnen. Der Aufruf dieser Methode mit <code>"2d"</code> gibt ein {{domxref("CanvasRenderingContext2D")}} Objekt zurück, während er mit <code>"experimental-webgl"</code> oder <code>"webgl"</code> ein {{domxref("WebGLRenderingContext")}} Objekt zurückgibt. Dieser context ist nur bei Browsern möglich, die <a href="/en-US/docs/Web/WebGL">WebGL</a> unterstützen.</dd>
+ <dt>{{domxref("HTMLCanvasElement.toDataURL()")}}</dt>
+ <dd>Returns a data-URL containing a representation of the image in the format specified by the <code>type</code> parameter (defaults to <code>png</code>). The returned image is in a resolution of 96dpi.</dd>
+ <dt>{{domxref("HTMLCanvasElement.toBlob()")}}</dt>
+ <dd>Creates a {{domxref("Blob")}} object representing the image contained in the canvas; this file may be cached on the disk or stored in memory at the discretion of the user agent.</dd>
+ <dt>{{domxref("HTMLCanvasElement.transferControlToOffscreen()")}} {{experimental_inline}}</dt>
+ <dd>Transfers control to an {{domxref("OffscreenCanvas")}} object, either on the main thread or on a worker.</dd>
+ <dt>{{domxref("HTMLCanvasElement.mozGetAsFile()")}} {{non-standard_inline}} {{deprecated_inline}}</dt>
+ <dd>Returns a {{domxref("File")}} object representing the image contained in the canvas; this file is a memory-based file, with the specified <code>name</code>. If <code>type</code> is not specified, the image type is <code>image/png</code>.</dd>
