Class Vector

java.lang.Object
com.lowagie.text.pdf.parser.Vector
@Deprecated public class Vector extends Object
Deprecated.
Represents a vector (i.e. a point in space). This class is completely unrelated to the Vector class in the standard JRE.

For many PDF related operations, the z coordinate is specified as 1 This is to support the coordinate transformation calculations. If it helps, just think of all PDF drawing operations as occurring in a single plane with z=1.

  • Constructor Details

    • Vector

      public Vector(float x, float y, float z)
      Deprecated.
      Creates a new Vector
      Parameters:
      x - the X coordinate
      y - the Y coordinate
      z - the Z coordinate

  • Method Details

    • get

      public float get(int index)
      Deprecated.
      Gets the value from a coordinate of the vector
      Parameters:
      index - the index of the value to get (I1, I2 or I3)
      Returns:
      value from a coordinate of the vector

    • cross

      public Vector cross(Matrix by)
      Deprecated.
      Computes the cross product of this vector and the specified matrix
      Parameters:
      by - the matrix to cross this vector with
      Returns:
      the result of the cross product

    • subtract

      public Vector subtract(Vector v)
      Deprecated.
      Computes the difference between this vector and the specified vector
      Parameters:
      v - the vector to subtract from this one
      Returns:
      the results of the subtraction

    • add

      public Vector add(Vector v)
      Deprecated.
      Computes the sum of this vector and the specified vector
      Parameters:
      v - the vector to subtract from this one
      Returns:
      the results of the subtraction

    • cross

      public Vector cross(Vector with)
      Deprecated.
      Computes the cross product of this vector and the specified vector
      Parameters:
      with - the vector to cross this vector with
      Returns:
      the cross product

    • dot

      public float dot(Vector with)
      Deprecated.
      Computes the dot product of this vector with the specified vector
      Parameters:
      with - the vector to dot product this vector with
      Returns:
      the dot product

    • length

      public float length()
      Deprecated.
      Computes the length of this vector Note: If you are working with raw vectors from PDF, be careful - the Z axis will generally be set to 1. If you want to compute the length of a vector, subtract it from the origin first (this will set the Z axis to 0).

      For example: aVector.subtract(originVector).length();

      Returns:
      the length of this vector

    • lengthSquared

      public float lengthSquared()
      Deprecated.
      Computes the length squared of this vector.

      The square of the length is less expensive to compute, and is often useful without taking the square root.

      Note: See the important note under length()

      Returns:
      the square of the length of the vector

    • toString

      public String toString()
      Deprecated.
      Overrides:
      toString in class Object
