PTSelection

@interface PTSelection : NSObject

A class representing the current text selection.

  • Declaration

    Objective-C

    - (int)GetPageNum;

    Swift

    func getPageNum() -> Int32

    Return Value

    the page number containing the selected text.

  • Returns the list of tight bounding quads in the current text selection.

    e.g., (quad[0], quad[1]) is the coordinate of vertex 0, and (quad[4], quad[5]) is the coordinate of vertex 2. Note that it is only ensured that the four vertices are arranged sequentially; it is possible in practice that (quad[0], quad[1]) is the coordinate of any vertex.

    Note

    the ‘quads’ array is owned by the current selection and does not need to be explicitly released.

    Declaration

    Objective-C

    - (PTVectorQuadPoint *)GetQuads;

    Swift

    func getQuads() -> PTVectorQuadPoint!

    Parameters

    quads

    - Sets a pointer to an array of vertices representing a list of bounding quads for the selected text. Each bounding quad is represented using 8 numbers in an array of doubles. Each two consecutive values represent the x and y coordinates of a quad vertex and the four vertices are arranged counter-clockwisely,

        3--------2
    |        |
    |        |
    |        |
    0--------1

    Return Value

    the number of quads in ‘quads’ array.

  • Declaration

    Objective-C

    - (NSString *)GetAsUnicode;

    Swift

    func getAsUnicode() -> String!

    Return Value

    the current text selection represented as an Unicode string.

  • Note

    this function can be used to implement clipboard copy and paste that preserves text formating.

    Declaration

    Objective-C

    - (NSString *)GetAsHtml;

    Swift

    func getAsHtml() -> String!

    Return Value

    the current text selection in HTML format. HTML text will contain styling information such as text color, font size, style etc.

  • Undocumented

    Declaration

    Objective-C

    - (instancetype)init;

    Swift

    init!()
