Visibility	`showWhen`	Boolean	Determines whether the image is displayed in the component. When set to false, the image is hidden and is not evaluated. Default: true.

Examples

To experiment with examples, copy and paste the expression into an interface object.

Displaying a document image using a constant

To test this example, replace cons!MY_PNG with a constant that points to a document in your environment.

Note that this uses the document() function to access the name of the document to display in the interface.

a!imageField(
  label: document(
    documentId: cons!MY_PNG,
    property: "name"
  ),
  labelPosition: "ABOVE",
  images: {
    a!documentImage(
      document: cons!MY_PNG
    )
  }
)
