public class FormatArgUtils
extends java.lang.Object

A class for converting Format objects to and from strings that can be used as arguments in command-line programs, or as parameters in URLs. The syntax is this: all elements are separated by a colon. Everything is uppercase by default, but case is ignored. Only thing that is lowercase is x in dimension. Generally, each item corresponds to a constructor argument. The Format subclass is inferred from the encoding. ? is used to indicate Format.NOT_SPECIFIED (-1). floating point values in audio formats are done as integers. In audio formats, Big endian is B, little endian is L, signed is S, unsigned is U Data types: B is byte[], S is short[], I is int[] Dimension: [width]x[height], like "640x480" Trailing not specified values may be omitted. new AudioFormat(AudioFormat.LINEAR, 44100.0, 16, 2) would be LINEAR:44100:16:2 TODO: support WavAudioFormat, video formats, and other missing audio formats.
