public class PictReader
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.

getDimensions(byte[] stuff)
Get the dimensions of a PICT file from the first 4 bytes after header. |
protected void |
initFile(String id)
Initializes the given file (parsing header information, etc.). |
boolean |
isThisType(byte[] block)
Checks if the given block is a valid header for this file format. |
