      org.jfree.pixie.wmf.records.MfCmdRestoreDc

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, �1 restores the most recently saved state.

Constructor Detail

MfCmdRestoreDc

public MfCmdRestoreDc()

Method Detail

replay

public void replay(WmfFile file)

Replays the command on the given WmfFile.

Specified by:

replay in class MfCmd

Parameters:

file - the meta file.

getInstance

public MfCmd getInstance()

Creates a empty unintialized copy of this command implementation.

Specified by:

getInstance in class MfCmd

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.

Specified by:

setRecord in class MfCmd

Parameters:

record - the raw data that makes up the record.

getRecord

public MfRecord getRecord()
                   throws RecordCreationException

Creates a new record based on the data stored in the MfCommand.

Specified by:

getRecord in class MfCmd

Returns:

the created record.

Throws:

RecordCreationException

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 class MfCmd

Returns:

the function identifier.

getNSavedDC

public int getNSavedDC()

setNSavedDC

public void setNSavedDC(int id)

toString

public java.lang.String toString()

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 class 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.

Specified by:

scaleYChanged in class MfCmd
