ImageDisplay

Displays an image view with ability to zoom in, zoom out, zoom to fit. It can also automatically resizes to parent size. When zoomToFit is set to true the image is sized to fit the parent scroll pane.

Sample usage (full detains in ImageDisplayDemoApp)

object ImageDisplayDemoApp extends JFXApp {

  private val imageDisplay = new ImageDisplay()

  stage = new PrimaryStage {
    scene = new Scene(640, 480) {
      title = "ImageDisplay Demo"
      root = new BorderPane {
        top = new ToolBar {
          items = Seq(
            new Button("Open...") {
              onAction = () => onFileOpen()
            },
            new Button("Zoom In") {
              onAction = () => imageDisplay.zoomIn()
              disable <== imageDisplay.zoomToFit
            },
            new Button("Zoom Out") {
              onAction = () => imageDisplay.zoomOut()
              disable <== imageDisplay.zoomToFit
            },
            new ToggleButton("Zoom to fit") {
              selected <==> imageDisplay.zoomToFit
            }
          )
        }
        center = imageDisplay.view
      }
    }
  }
}
