public class MfCmdStretchDibits
extends MfCmd

The StretchDIBits function copies the color data for a rectangle of pixels in a DIB to the specified destination rectangle. If the destination rectangle is larger than the source rectangle, this function stretches the rows and columns of color data to fit the destination rectangle. If the destination rectangle is smaller than the source rectangle, this function compresses the rows and columns by using the specified raster operation.

Constructor Detail

MfCmdStretchDibits

public MfCmdStretchDibits()

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.

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.

getROP

public int getROP()

setROP

public void setROP(int rop)

getImage

public BufferedImage getImage()

setImage

public void setImage(BufferedImage image)

getUsage

public int getUsage()

setUsage

public void setUsage(int usage)

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 - if an error occured while generating the record.

toString

public String toString()

Overrides:

toString in class Object

setSrcRect

public void setSrcRect(int x,
                       int y,
                       int w,
                       int h)

setDestRect

public void setDestRect(int x,
                        int y,
                        int w,
                        int h)

getSrcRect

public Rectangle getSrcRect()

getDestRect

public Rectangle getDestRect()

getScaledSrcRect

public Rectangle getScaledSrcRect()

getScaledDestRect

public Rectangle getScaledDestRect()

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
