Constructor Detail

public TJScalingFactor(int num,
                       int denom)

Create a TurboJPEG scaling factor instance. Parameters:num - numeratordenom - 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 factorReturns:the scaled value of dimension.

equals

public boolean equals([TJScalingFactor](TJScalingFactor.html "class in org.libjpegturbo.turbojpeg")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 oneReturns: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.
