    Method
    Description
    static int
    emu(float pixels, int dpi)
    Convert an int value from pixels to EMU
    static int
    halfPoint(float pixels, int dpi)
     
    static double
    inch(double pixels, int dpi)
    Converts pixels to inches without decimal truncation.
    static double
    inchFloor2Dec(double pixels, int dpi)
     
    static double
    inchFloor4Dec(double pixels, int dpi)
     
    static double
    inchRound2Dec(double pixels, int dpi)
     
    static double
    inchRound4Dec(double pixels, int dpi)
     
    static int
    pixel(float points, int dpi)
    Converts points back to pixels, the inverse of point(float, int).
    static float
    point(float pixels, int dpi)
    Converts pixels to points, for output formats that only offer a fixed set of line thicknesses and thus need the value expressed in physical units.
    static int
    twip(float pixels, int dpi)
    Convert a float value to twips
