Method Detail

toString

public java.lang.String toString()

Description copied from class: Record

get a string representation of the record (for biffview/debugging)

Overrides:

toString in class Record

serialize

public void serialize(LittleEndianOutput out)

Description copied from class: StandardRecord

Write the data content of this BIFF record. The 'ushort sid' and 'ushort size' header fields have already been written by the superclass.

The number of bytes written must equal the record size reported by RecordBase.getRecordSize()} minus four ( record header consisting of a 'ushort sid' and 'ushort reclength' has already been written by their superclass).

Specified by:

serialize in class StandardRecord

Parameters:

out - the output object

getDataSize

protected int getDataSize()

Specified by:

getDataSize in class StandardRecord

getSid

public short getSid()

Description copied from class: Record

return the non static version of the id for this record.

Specified by:

getSid in class Record

Returns:

he id for this record

getColor

public byte[] getColor(int byteIndex)

Returns the color value at a given index

Parameters:

byteIndex - palette index, must be >= 0x8

Returns:

the RGB triplet for the color, or null if the specified index does not exist

setColor

public void setColor(short byteIndex,
                     byte red,
                     byte green,
                     byte blue)

Sets the color value at a given index If the given index is greater than the current last color index, then black is inserted at every index required to make the palette continuous.

Parameters:

byteIndex - the index to set; if this index is less than 0x8 or greater than 0x40, then no modification is made

red - the red color part

green - the green color part

blue - the blue color part
