PTFreeText

@interface PTFreeText : PTMarkup

A FreeText annotation (PDF 1.3) displays text directly on the page. Unlike an ordinary Text annotation, a FreeText annotation has no open or closed state; The content of the FreeText annotation is always visible instead of being displayed in a popup window.

  • Creates a FreeText annotation and initializes it using given Cos/SDF object.

    Note

    The constructor does not copy any data, but is instead the logical equivalent of a type cast.

    Declaration

    Objective-C

    - (instancetype)initWithD:(PTObj *)d;

    Swift

    init!(d: PTObj!)

    Parameters

    d

    The Cos/SDF object to initialze the annotation with.
