| - * An object that can be drawn to a [CanvasRenderingContext2D] object with
|
| - * [CanvasRenderingContext2D.drawImage],
|
| - * [CanvasRenderingContext2D.drawImageToRect],
|
| - * [CanvasRenderingContext2D.drawImageScaled], or
|
| - * [CanvasRenderingContext2D.drawImageScaledFromSource].
|
| + * An object that can be drawn to a 2D canvas rendering context.
|
| *
|
| - * If the CanvasImageSource is an [ImageElement] then the element's image is
|
| - * used. If the [ImageElement] is an animated image, then the poster frame is
|
| - * used. If there is no poster frame, then the first frame of animation is used.
|
| + * This object is either an [ImageElement], [VideoElement], or
|
| + * [CanvasElement].
|
| *
|
| - * If the CanvasImageSource is a [VideoElement] then the frame at the current
|
| - * playback position is used as the image.
|
| + * The image drawn to the canvas differs by implementation:
|
| *
|
| - * If the CanvasImageSource is a [CanvasElement] then the element's bitmap is
|
| - * used.
|
| + * * If this object is an [ImageElement], then this element's image is
|
| + * drawn to the canvas. If this element is an animated image, then this
|
| + * element's poster frame is drawn. If this element has no poster frame, then
|
| + * the first frame of animation is drawn.
|
| *
|
| - * ** Note: ** Currently, all versions of Internet Explorer do not support
|
| - * drawing a VideoElement to a canvas. Also, you may experience problems drawing
|
| + * * If this object is a [VideoElement], then the frame at this element's current
|
| + * playback position is drawn to the canvas.
|
| + *
|
| + * * If this object is a [CanvasElement], then this element's bitmap is drawn to
|
| + * the canvas.
|
| + *
|
| + * **Note:** Currently all versions of Internet Explorer do not support
|
| + * drawing a video element to a canvas. You may also encounter problems drawing
|
| * a video to a canvas in Firefox if the source of the video is a data URL.
