Method Detail

getEmfPlusRecordType

public HemfPlusRecordType getEmfPlusRecordType()

Specified by:

getEmfPlusRecordType in interface HemfPlusRecord

getFlags

public int getFlags()

Specified by:

getFlags in interface HemfPlusRecord

init

public long init(LittleEndianInputStream leis,
                 long dataSize,
                 long recordId,
                 int flags)
          throws java.io.IOException

Description copied from interface: HemfPlusRecord

Init record from stream

Specified by:

init in interface HemfPlusRecord

Parameters:

leis - the little endian input stream

dataSize - the size limit for this record

recordId - the id of the HemfPlusRecordType

flags - the record flags

Returns:

count of processed bytes

Throws:

java.io.IOException - when the inputstream is malformed

getVersion

public HemfPlusHeader.EmfPlusGraphicsVersion getVersion()

isEmfPlusDualMode

public boolean isEmfPlusDualMode()

If set, this flag indicates that this metafile is "dual-mode", which means that it contains two sets of records, each of which completely specifies the graphics content. If clear, the graphics content is specified by EMF+ records, and possibly EMF records that are preceded by an EmfPlusGetDC record. If this flag is set, EMF records alone SHOULD suffice to define the graphics content. Note that whether the "dual-mode" flag is set or not, some EMF records are always present, namely EMF control records and the EMF records that contain EMF+ records.

Returns:

true if dual-mode is enabled

getEmfPlusFlags

public long getEmfPlusFlags()

getLogicalDpiX

public long getLogicalDpiX()

getLogicalDpiY

public long getLogicalDpiY()

draw

public void draw(HemfGraphics ctx)

Description copied from interface: HemfPlusRecord

Draws the record, the default redirects to the parent WMF record drawing

Specified by:

draw in interface HemfPlusRecord

Parameters:

ctx - the drawing context

calcBounds

                       java.awt.geom.Rectangle2D viewport,

Specified by:

calcBounds in interface HemfPlusRecord
