Class MfCmdRestoreDc
public class MfCmdRestoreDc
The RestoreDC function restores a device context (DC) to the specified state. The DC is
restored by popping state information off a stack created by earlier calls to the
SaveDC function.
BOOL RestoreDC( HDC hdc, // handle to DC int nSavedDC // restore state
);
Parameters nSavedDC [in] Specifies the saved state to be restored. If this parameter is
positive, nSavedDC represents a specific instance of the state to be restored. If this
parameter is negative, nSavedDC represents an instance relative to the current state.
For example, 0x01 restores the most recently saved state.

MfCmdRestoreDc
public MfCmdRestoreDc()
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.
getNSavedDC
public int getNSavedDC()
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
setNSavedDC
public void setNSavedDC(int id)
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.
