The following parameters are supported:
|!Parameters |!Description |
|''selector'' |CSS selector identifying the DOM node to be saved as an image (defaults to `body`) |
|''selector'' |CSS selector identifying the DOM node to be saved as an image (defaults to `body`). If multiple DOM nodes are returned by the selector then the first one is used |
|''format'' |Save format: ''png'', ''jpeg'' or ''svg'' (defaults to ''png'') |
|''quality'' |Optional quality 0 to 1 for JPEG images (note that the default quality is 1, and this default is applied even if the quality is explicitly specified as `0`. To force a low quality JPEG image it is therefore necessary to specify a small non-zero value such as `0.001`) |
|''scale'' |Optional scale factor for the image (defaults to 1) |
