Constructor Detail

• TJScalingFactor

  public TJScalingFactor(int num,
                 int denom)

  Create a TurboJPEG scaling factor instance.

  Parameters:

  num - numerator

  denom - denominator

Method Detail

• getNum

  public int getNum()

  Returns numerator

  Returns:

  numerator

• getDenom

  public int getDenom()

  Returns denominator

  Returns:

  denominator

• getScaled

  public int getScaled(int dimension)

  Returns the scaled value of dimension. This function performs the integer equivalent of ceil(dimension * scalingFactor).

  Parameters:

  dimension - width or height to multiply by this scaling factor

  Returns:

  the scaled value of dimension.

• equals

  public boolean equals(TJScalingFactor other)

  Returns true or false, depending on whether this instance and other have the same numerator and denominator.

  Parameters:

  other - the scaling factor against which to compare this one

  Returns:

  true or false, depending on whether this instance and other have the same numerator and denominator.

• isOne

  public boolean isOne()

  Returns true or false, depending on whether this instance is equal to 1/1.

  Returns:

  true or false, depending on whether this instance is equal to 1/1.
