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.
