app_state string <optional>
 is an optional parameter specifying the appearance state (e.g. "Off", "On", etc) under which the new appearance should be stored. If appearance_state is NULL, the annotation will have only one annotation state.
Inherited From:
Returns:
Type
Promise.<void>

resize(newrect)

Scales the geometry of the annotation so that its appearance would now fit a new rectangle on the page, in user units. Users still have to call RefreshAppearance() later if they want a corresponding appearance stream to be generated for the new rectangle. The main reason for not combining the two operations together is to be able to resize annotations that do not have an appearance stream.
Parameters:
Name Type Description
newrect PDFNet.Rect A reference to the new rectangle to which this annotation has to be resized.
Inherited From:
Returns:
Type

setBorderStyle(bs [, oldStyleOnly])

Sets the border style for the annotation.
Parameters:
Name Type Argument Description

oldStyleOnly boolean <optional>
 PDF manual specifies two ways to add border information to an annotation object, either through an array named 'Border' (PDF 1.0), or a dictionary called 'BS' (PDF 1.2) the latter taking precedence over the former. However, if you want to create a border with rounded corners, you can only do that using PDF 1.0 Border specification, in which case if you call SetBorderStyle() set the parameter oldStyleOnly to true. This parameter has a default value of false in the API and does not need to be used otherwise.
