scale property

num get scale

Gets or sets the scale transform of this Diagram. Value must be a positive number. The default value is 1. Any new value will be coerced to be between #minScale and #maxScale.

Scale can automatically be set by the #autoScale property. There are also #initialScale and #initialAutoScale for setting the scale on (re)initialization of a Diagram.

Setting this property does not notify about any changed event. However you can listen with #addDiagramListener for a DiagramEvent with the name "ViewportBoundsChanged".

If you set this property any replacement of the #model will result in a layout and a computation of new #documentBounds, which in turn may cause the diagram to be scrolled and zoomed, depending on various Diagram properties named "initial...". You may want to set #initialScale instead of setting this property around the time that you are loading a model.

Implementation

_i2.num get scale => _i4.getProperty(
      this,
      'scale',
    );

set scale (num value)

Implementation

set scale(_i2.num value) {
  _i4.setProperty(
    this,
    'scale',
    value,
  );
}
