The HTMLImageElement used in the image request.
Object.defineProperty(ImageLoader.prototype, 'workingImageElement',
get: function(),
set: function(value)
)
null by default. Can be set to a custom HTMLImageElement to use for the image request. Otherwise, a new HTMLImageElement will be created as needed.
A user can pass their own HTMLImageElement with custom settings. When Run is called and an HTMLImageElement is needed, WorkingImageElement will be set to a new HTMLImageElement if it is null. An HTMLImageElement is only needed when the UrlMode is the default ImageLoaderUrlMode.ImageUrl.
Some attributes of the WorkingImageElement will be set automatically: src
will be set from Url, crossOrigin
will be set from ImgCrossOrigin, and event handlers will be added to support Done, Fail, and Always.
If making requests using ImageLoaderUrlMode.AjaxXml or ImageLoaderUrlMode.AjaxDataUrl, see Xhr.
See Run for more information.
