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;
