How to convert a BufferedImage to gif in java

Question

I want to convert a BufferedImage to gif. I already converted BufferedImage to jpeg with a function and the output was Byte[] so I could send it over the inet with a socket connection.

I need a gif encode function similiar to this jpeg encode function:

public static byte[] getImageAsJPEG(BufferedImage image) throws ImageFormatException, IOException { ByteArrayOutputStream output = new ByteArrayOutputStream(); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(output); JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(image); param.setQuality(0.9f, false); encoder.setJPEGEncodeParam(param); encoder.encode(image); return output.toByteArray(); }

you can create using ImageIO, but notice that there are restrictions - see docs.oracle.com/javase/7/docs/api/javax/imageio/… — Leo

Use:

ImageIO.write(image, "GIF", output);

As in:

public static byte[] getImageAsGIF(BufferedImage image) throws ImageFormatException, IOException { ByteArrayOutputStream output = new ByteArrayOutputStream(); ImageIO.write(image, "GIF", output); return output.toByteArray(); }
