Method Details

initEncoding

private static Charset initEncoding()

readFixedPoint

public static double readFixedPoint(DataInput pStream)
                             throws IOException

Reads a fixed point number from the given stream.

Parameters:

pStream - the input stream

Returns:

the number as a double.

Throws:

IOException - if an I/O error occurs during read

readIdString

static String readIdString(DataInput pStream)
                    throws IOException

Throws:

IOException

readDimension

public static Dimension readDimension(DataInput pStream)
                               throws IOException

Reads a dimension from the given stream.

Parameters:

pStream - the input stream

Returns:

the dimension read

Throws:

IOException - if an I/O error occurs during read

readStr31

public static String readStr31(DataInput pStream)
                        throws IOException

Reads a 32 byte fixed length Pascal string from the given input. The input stream must be positioned at the length byte of the text, the text will be no longer than 31 characters long.

Parameters:

pStream - the input stream

Returns:

the text read

Throws:

IOException - if an I/O exception occurs during reading

readPascalString

public static String readPascalString(DataInput pStream)
                               throws IOException

Reads a Pascal String from the given stream. The input stream must be positioned at the length byte of the text, which can thus be a maximum of 255 characters long.

Parameters:

pStream - the input stream

Returns:

the text read

Throws:

IOException - if an I/O exception occurs during reading

readPattern

public static Pattern readPattern(DataInput pStream)
                           throws IOException

Reads a pattern from the given stream.

Parameters:

pStream - the input stream

Returns:

the pattern read

Throws:

IOException - if an I/O error occurs during read

readPattern

public static Pattern readPattern(DataInput pStream,
 Color fg,
 Color bg)
                           throws IOException

Throws:

IOException

readColorPattern

public static Pattern readColorPattern(DataInput pStream)
                                throws IOException

Reads a variable width color pattern from the given stream

Parameters:

pStream - the input stream

Returns:

the pattern read

Throws:

IOException - if an I/O error occurs during read

readRGBColor

public static Color readRGBColor(DataInput pStream)
                          throws IOException

Reads an RGBColor record from the given stream.

Parameters:

pStream - the input stream

Returns:

the color read

Throws:

IOException - if an I/O error occurs during read

readColorTable

public static IndexColorModel readColorTable(DataInput pStream,
 int pPixelSize)
                                      throws IOException

Reads a ColorTable data structure from the given stream.

Parameters:

pStream - the input stream

pPixelSize - the pixel size

Returns:

the indexed color model created from the ColorSpec records read.

Throws:

IOException - if an I/O error occurs during read
