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 method performs the integer equivalent of Math.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.
