Printer Widget change the Legend element of the Layout Options with images

Mehretab

I am developing an application based on WAB. Since I have some services with complicated legend I made the legend widget to reference to a pre made images for legend.

 I have my own print template with Title, Author, copyright and legend elements.  I am working to include these images in the place of the legend element or any other element so that the map got an appropriate legend element in the printout. 

If you see the PrintTemplate() object we have access to these layout elements in the  LayoutOptions object as properties.
