MfCmdScaleViewportExt
public MfCmdScaleViewportExt()
The default constructor, adjusts the scale to 1.
getFunction
public int getFunction()
Reads the function identifier. Every record type is identified by a function number
corresponding to one of the Windows GDI functions used.
- getFunction in interface MfCmd
getInstance
public MfCmd getInstance()
Creates a empty unintialized copy of this command implementation.
- getInstance in interface MfCmd
- a new instance of the command.
getXDenom
public int getXDenom()
getXNum
public int getXNum()
getXScale
public double getXScale()
getYDenom
public int getYDenom()
getYNum
public int getYNum()
getYScale
public double getYScale()
replay
public void replay(WmfFile file)
Replays the command on the given WmfFile.
- replay in interface MfCmd
scaleXChanged
protected void scaleXChanged()
A callback function to inform the object, that the x scale has changed and the
internal coordinate values have to be adjusted.
- scaleXChanged in interface MfCmd
scaleYChanged
protected void scaleYChanged()
A callback function to inform the object, that the y scale has changed and the
internal coordinate values have to be adjusted.
- scaleYChanged in interface MfCmd
setRecord
public void setRecord(MfRecord record)
Reads the command data from the given record and adjusts the internal parameters
according to the data parsed.
After the raw record was read from the datasource, the record is parsed by the
concrete implementation.
- setRecord in interface MfCmd
record
- the raw data that makes up the record.

int xDenom)
setYScale
public void setYScale(int yNum,
int yDenom)
