    • WMFHeaderProperties

      public WMFHeaderProperties(File wmffile) throws IOException
      Creates a new WMFHeaderProperties, and sets the associated WMF File.
      Parameters:
      wmffile - the WMF Metafile
      Throws:
      IOException

    • WMFHeaderProperties

      public WMFHeaderProperties()

      public void setFile(File wmffile) throws IOException
      Creates the properties associated file.
      Throws:
      IOException

    • reset

      public void reset()
      Resets the internal storage and viewport coordinates.
      Specified by:
      reset in class AbstractWMFReader

    • getStream

      public DataInputStream getStream()
      Get the associated stream.

    • readRecords

      protected boolean readRecords(DataInputStream is) throws IOException
      Description copied from class: AbstractWMFReader
      Read this InputStream records. The aldus placeable header have already been read (see AbstractWMFReader.read(DataInputStream)). The behavior of this method is left to the subclass. Each Metafile record is composed of :
      • the size of the Record in int (32 bits)
      • the function ID for the Record on a short word (16 bits)
      • the function parameters, according to the WMF Metafile specification. the remaining size in short words (16 bits) for the parameters is equal to the total size for the record minus 3 short words (= 16 + 32 bits)

      Example :

      while (functionId > 0) {
        recSize = readInt( is );
        // Subtract size in 16-bit words of recSize and functionId;
        recSize -= 3;
        functionId = readShort( is );
        if ( functionId <= 0 )
          break;
        switch ( functionId ) {
          case WMFConstants.<a WMF function ID> {
            do something when this function is encountered
          }
          break;

          default:
             for ( int j = 0; j < recSize; j++ )
               readShort(is);
          break;
      Specified by:
      readRecords in class AbstractWMFReader
      Throws:
      IOException

    • resetBounds

      private void resetBounds()

    • resizeBounds

      private void resizeBounds(int x, int y)
      resize Bounds for each primitive encountered. Only elements that are in the overall width and height of the Metafile are kept.

    • resizeImageBounds

      private void resizeImageBounds(int x, int y)
      resize Bounds for each image primitive encountered. Only elements that are in the overall width and height of the Metafile are kept.

    • getColorFromObject

      private Color getColorFromObject(int brushObject)
      get the Color corresponding with the Object (pen or brush object).

    • paint

      private void paint(int brushObject, int penObject, Shape shape)
      Resize the bounds of the WMF image according with the bounds of the geometric Shape. There will be no resizing if one of the following properties is true :
      • the brush and the pen objects are invalid input: '<' 0 (null objects)
      • the color of the geometric Shape is white, and no other Shapes has occured

    • paintWithPen

      private void paintWithPen(int penObject, Shape shape)
      Resize the bounds of the WMF image according with the bounds of the geometric Shape. There will be no resizing if one of the following properties is true :
      • the pen objects is invalid input: '<' 0 (null object)
      • the color of the geometric Shape is white, and no other Shapes has occured

    • getVerticalAlignmentValue

      private float getVerticalAlignmentValue(TextLayout layout, int vertAlign)
      get the vertical Alignment value for the text.
