Syntax
JavaScript Syntax
TypeScript Syntax
renderLayers(clipRect: LeadRectD, layers: AnnLayerCollection, container: AnnContainer, runMode: boolean): void;Parameters
clipRect
The destination clip rectangle LeadRectD in container coordinates. The engine will only render into this area. Pass
LeadRectD.Empty if you do not want to use a clip rectangle.
layers
The layers to render.
container
The owner container.
runMode
true to render this container in run mode; otherwise, false.
Remarks
This method uses the mapper in container to calculate the destination rectangle and any other transform to be applied.
The value of runMode controls whether this method renders the thumbs, selection objects and other parts used in design mode of the annotation objects as follows:
-
To render the current state of the designers "as is" (for example, when performing automation in a viewer), pass false.
-
Most of the time when burning annotations to an image the design mode parts are not required, so you pass true.
