Class pv.Image
Extends pv.Bar.
Represents an image. Images share the same layout and style properties as bars, in conjunction with an external image such as PNG or JPEG. The image is specified via the #url property. The fill, if specified, appears beneath the image, while the optional stroke appears above the image.
TODO Restore support for dynamic images (such as heatmaps). These were supported in the canvas implementation using the pixel buffer API; although SVG does not support pixel manipulation, it is possible to embed a canvas element in SVG using foreign objects.
TODO Allow different modes of image placement: "scale" -- scale and preserve aspect ratio, "tile" -- repeat the image, "center" -- center the image, "fill" -- scale without preserving aspect ratio.
See pv.Bar for details on positioning properties.
Defined in: Image.js.
