public class MfCmdRestoreDc extends MfCmd
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.

Method Detail
-
replay
public void replay(WmfFile file)
Replays the command on the given WmfFile.
-
getInstance
public MfCmd getInstance()
Creates a empty unintialized copy of this command implementation.- Specified by:
getInstance
in classMfCmd
- Returns:
- a new instance of the command.
-
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.
-
getRecord
public MfRecord getRecord() throws RecordCreationException
Creates a new record based on the data stored in the MfCommand.- Specified by:
getRecord
in classMfCmd
- Returns:
- the created record.
- Throws:
RecordCreationException
- if an error occured while generating the record.
-
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.- Specified by:
getFunction
in classMfCmd
- Returns:
- the function identifier.
-
getNSavedDC
public int getNSavedDC()
-
setNSavedDC
public void setNSavedDC(int id)
-
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.- Specified by:
scaleXChanged
in classMfCmd
-
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.- Specified by:
scaleYChanged
in classMfCmd
