public class PictReader

extends FormatReader

PictReader is the file format reader for Apple PICT files. Most of this code was adapted from the PICT readers in JIMI (http://java.sun.com/products/jimi/index.html), ImageMagick (http://www.imagemagick.org), and Java QuickDraw.

Field Summary

protected byte[]	bytes Pixel bytes.
protected int	height Height of the image.
protected RandomAccessFile	in Current file.
protected boolean	little Flag indicating whether current file is little endian.
protected short[][]	lookup Color lookup table for palette color images.
protected int	pictState Image state.
protected int	pt Pointer into the array of bytes representing the file.
protected LegacyQTReader	qtReader Helper reader in case this one fails.
protected int	rowBytes Number of bytes in a row of pixel data (variable).
protected int	state Decoder state.
protected Vector	strips Vector of byte arrays representing individual rows.
protected boolean	versionOne Whether or not the file is PICT v1.
protected int	width Width of the image.
