outputFormat

The format of the resulting image. Only PNG images are supported.

The default is png. If you specify png, the API returns an HTTP response with the content-type set to text/xml. The image data is in a MetricWidgetImage field. For example:

<GetMetricWidgetImageResponse xmlns=<URLstring>>

<GetMetricWidgetImageResult>

<MetricWidgetImage>

iVBORw0KGgoAAAANSUhEUgAAAlgAAAGQEAYAAAAip...

</MetricWidgetImage>

</GetMetricWidgetImageResult>

<ResponseMetadata>

<RequestId>6f0d4192-4d42-11e8-82c1-f539a07e0e3b</RequestId>

</ResponseMetadata>

</GetMetricWidgetImageResponse>

The image/png setting is intended only for custom HTTP requests. For most use cases, and all actions using an Amazon Web Services SDK, you should use png. If you specify image/png, the HTTP response has a content-type set to image/png, and the body of the response is a PNG image.
