PTInk

@interface PTInk : PTMarkup

An ink annotation (PDF 1.3) represents a freehand “scribble” composed of one or more disjoint paths. When opened, it shall display a pop-up window containing the text of the associated note.

  • Creates an Ink 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.

  • Undocumented

    Declaration

    Objective-C

    - (instancetype)init;

    Swift

    init!()
  • Undocumented

    Declaration

    Objective-C

    - (instancetype)initWithAnn: (PTAnnot*)ann;

    Swift

    init!(ann: PTAnnot!)
  • Creates a new Ink annotation in the specified document.

    Declaration

    Objective-C

    + (PTInk *)Create:(PTSDFDoc *)doc pos:(PTPDFRect *)pos;

    Swift

    class func create(_ doc: PTSDFDoc!, pos: PTPDFRect!) -> PTInk!

    Parameters

    doc

    A document to which the Ink annotation is added.

    pos

    A rectangle specifying the Ink annotation’s bounds in default user space units.

    Return Value

    A newly created blank Ink annotation.

  • Returns number of paths in the annotation.

    Note

    Each path is an array of Point objects specifying points along the path. When drawn, the points shall be connected by straight lines or curves in an implementation-dependent way.

    Declaration

    Objective-C

    - (int)GetPathCount;

    Swift

    func getPathCount() -> Int32

    Return Value

    An integer representing the number of paths in the ‘InkList’ entry of the annotation dictionary.

  • Returns number of points in a certain stroked path in the InkList.

    See

    GetPathCount()

    Declaration

    Objective-C

    - (int)GetPointCount:(unsigned int)pathindex;

    Swift

    func getPointCount(_ pathindex: UInt32) -> Int32

    Parameters

    pathindex

    path index for each the point count is returned. Index starts at 0.

    Return Value

    An integer representing the number of points in the stroked path of the Ink list.

  • Returns the specific point in a given path.

    Note

    Each path is an array of Point objects specifying points along the path. When drawn, the points shall be connected by straight lines or curves in an implementation-dependent way.

    Declaration

    Objective-C

    - (PTPDFPoint *)GetPoint:(unsigned int)pathindex
                  pointindex:(unsigned int)pointindex;

    Swift

    func getPoint(_ pathindex: UInt32, pointindex: UInt32) -> PTPDFPoint!

    Parameters

    pathindex

    path index for each the point is returned. Index starts at 0.

    pointindex

    index of point in the path. Index starts at 0.

    Return Value

    A Point object for specified path and point index.

  • Sets the specific point in the Ink List, adding it if needed.

    Note

    Ink annotation contains an array of paths. Each path is an array of Point objects specifying points along the path. When drawn, the points shall be connected by straight lines or curves in an implementation-dependent way.

    Declaration

    Objective-C

    - (void)SetPoint:(unsigned int)pathindex
          pointindex:(unsigned int)pointindex
                  pt:(PTPDFPoint *)pt;

    Swift

    func setPoint(_ pathindex: UInt32, pointindex: UInt32, pt: PTPDFPoint!)

    Parameters

    pathindex

    An unsigned integer indicating the index of the path.

    pointindex

    An unsigned integer indicating the index of the point within the stroked path indicated by the parameter “pathindex”.

    pt

    A Point object that is to be assigned.

  • Erase a rectangle area formed by pt1pt2 with width

    Declaration

    Objective-C

    - (BOOL)Erase:(PTPDFPoint *)pt1 pt2:(PTPDFPoint *)pt2 width:(double)width;

    Swift

    func erase(_ pt1: PTPDFPoint!, pt2: PTPDFPoint!, width: Double) -> Bool

    Parameters

    pt1

    A point object that is one end of the eraser segment

    pt2

    A point object that is the other end of the eraser segment

    width

    The half width of the eraser

    Return Value

    Whether an ink stroke was erased

  • Retrieves whether the Ink will draw like a highlighter.

    Declaration

    Objective-C

    - (BOOL)GetHighlightIntent;

    Swift

    func getHighlightIntent() -> Bool

    Return Value

    true if the Ink will draw like a highlighter. (multiply blend mode) If false it will draw in normal mode. (normal blend mode)

  • Enables or disables the Ink drawing like a highlighter.

    Declaration

    Objective-C

    - (void)SetHighlightIntent:(BOOL)highlight;

    Swift

    func setHighlightIntent(_ highlight: Bool)

    Parameters

    highlight

    true if the Ink will draw like a highlighter. (multiply blend mode) If false it will draw in normal mode. (normal blend mode)
