Class FastImageIO

java.lang.Object
  com.threerings.resource.FastImageIO

public class FastImageIO
extends Object

Provides routines for writing and reading uncompressed 8-bit color mapped images in a manner that is extremely fast and generates a minimal amount of garbage during the loading process.

Field Summary

protected static int[]	_cmap Used when loading our color map.
protected static Point	_origin Used when creating our writable raster.
static String	FILE_SUFFIX A suffix for use when storing raw images in bundles or on the file system.

Constructor Summary

FastImageIO()

Method Summary

static boolean	canWrite(BufferedImage image) Returns true if the supplied image is of a format that is supported by the fast image I/O services, false if not.
static BufferedImage	read(ByteBuffer byteBuffer) Reads an image from the supplied byte buffer (which must return the image format previously written via a call to write(java.awt.image.BufferedImage, java.io.OutputStream)).
static BufferedImage	read(File file) Reads an image from the supplied file (which must contain an image previously written via a call to write(java.awt.image.BufferedImage, java.io.OutputStream)).
static BufferedImage	read(InputStream in) Reads an image from the supplied input stream (which must return the image format previously written via a call to write(java.awt.image.BufferedImage, java.io.OutputStream)).
static void	write(BufferedImage image, OutputStream out) Writes the supplied image to the supplied output stream.
