java.lang.Object org.opensourcephysics.media.gif.GIFEncoder
public class GIFEncoder
GIFEncoder is a class which takes an image and saves it to a stream
using the GIF file format (Graphics Interchange
Format). A GIFEncoder
is constructed with either an AWT Image (which must be fully
loaded) or a set of RGB arrays. The image can be written out with a
call to Write
.
Three caveats:
java.awt.AWTException: Grabber returned false: 192
GIFEncoder is based upon gifsave.c, which was written and released by:

public GIFEncoder(java.awt.Image image) throws java.awt.AWTException
image
- The image to encode. The image must be
completely loaded.
java.awt.AWTException
- Will be thrown if the pixel grab fails. This
can happen if Java runs out of memory. It may also indicate that the image
contains more than 256 colors.public GIFEncoder(byte[][] r, byte[][] g, byte[][] b) throws java.awt.AWTException
Each array stores intensity values for the image. In other words, r[x][y] refers to the red intensity of the pixel at column x, row y.
r
- An array containing the red intensity values.g
- An array containing the green intensity values.b
- An array containing the blue intensity values.
java.awt.AWTException
- Will be thrown if the image contains more than
256 colors.Method Detail |

public void Write(java.io.OutputStream output) throws java.io.IOException
output
- The stream to output to. This should probably be a
buffered stream.
java.io.IOException
- Will be thrown if a write operation fails.
