Class MfCmdStretchDibits


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 Summary

Constructor Details

MfCmdStretchDibits

public MfCmdStretchDibits()
The default constructor, adjusts the scale to 1.

Method Details

getDestRect

public Rectangle getDestRect()

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.
Overrides:
getFunction in interface MfCmd
Returns:
the function identifier.

getImage

public BufferedImage getImage()

getInstance

public MfCmd getInstance()
Creates a empty unintialized copy of this command implementation.
Overrides:
getInstance in interface MfCmd
Returns:
a new instance of the command.

getROP

public int getROP()

getRecord

public MfRecord getRecord()
            throws RecordCreationException
Creates a new record based on the data stored in the MfCommand.
Overrides:
getRecord in interface MfCmd
Returns:
the created record.

getScaledDestRect

public Rectangle getScaledDestRect()

getScaledSrcRect

public Rectangle getScaledSrcRect()

getSrcRect

public Rectangle getSrcRect()

getUsage

public int getUsage()

replay

public void replay(WmfFile file)
Replays the command on the given WmfFile.
Overrides:
replay in interface MfCmd
Parameters:
file - the meta file.

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.
Overrides:
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.
Overrides:
scaleYChanged in interface MfCmd

setDestRect

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

setImage

public void setImage(BufferedImage image)

setROP

public void setROP(int rop)

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.

Overrides:
setRecord in interface MfCmd
Parameters:
record - the raw data that makes up the record.

setSrcRect

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

setUsage

public void setUsage(int usage)

toString

public String toString()
