====== DataUrl Variables ======

A DataUrl variable is used to stored an external file, with many informations. Usually an image. It can then be used as a [[Text Variables|Text Variable]] to set a canvas property.

To use a **Data-Url. Variable**, use the text ''$myVariable'', with the name corresponding to the field defined.

<code javascript>
"canvasFields": [
    {"type":"image", "src": "$portray", "left":5, "width":150, "top":40 ,"height":300}
]
