* @param {String} `sourceName` Source name. Note that, since scenes are also sources, you can also provide a scene name.
* @param {String (optional)} `embedPictureFormat` Format of the Data URI encoded picture. Can be "png", "jpg", "jpeg" or "bmp" (or any other value supported by Qt's Image module)
* @param {String (optional)} `saveToFilePath` Full file path (file extension included) where the captured image is to be saved. Can be in a format different from `pictureFormat`. Can be a relative path.
* @param {String (optional)} `fileFormat` Format to save the image file as (one of the values provided in the `supported-image-export-formats` response field of `GetVersion`). If not specified, tries to guess based on file extension.
* @param {int (optional)} `compressionQuality` Compression ratio between -1 and 100 to write the image with. -1 is automatic, 1 is smallest file/most compression, 100 is largest file/least compression. Varies with image type.
* @param {int (optional)} `width` Screenshot width. Defaults to the source's base width.
* @param {int (optional)} `height` Screenshot height. Defaults to the source's base height.
