Parameters:

data - The data array containing the escher records.

offset - The starting offset within the data array.

size - The number of bytes to read.

out - The output stream to write the results to.

Throws:

IOException

LittleEndian.BufferUnderrunException

dumpOld

public void dumpOld(long maxLength,
           InputStream in,
           PrintStream out)
             throws IOException,
                    LittleEndian.BufferUnderrunException

This version of dump is a translation from the open office escher dump routine.

Parameters:

maxLength - The number of bytes to read

in - An input stream to read from.

out - An output stream to write to.

Throws:

IOException

LittleEndian.BufferUnderrunException

propName

private String propName(short propertyId)

Returns a property name given a property id. This is used only by the old escher dump routine.

Parameters:

propertyId - The property number for the name

Returns:

A descriptive name.

getBlipType

private String getBlipType(byte b)

Returns the blip description given a blip id.

Parameters:

b - blip id

Returns:

A description.

dec1616

private String dec1616(int n32)

Straight conversion from OO. Converts a type of float.

outHex

Parameters:

bytes - How many bytes this hex value consists of.

in - The stream to read the hex value from.

out - The stream to write the nicely formatted hex value to.
