Method Detail

write

public void write(BufferedImage image,
                  OutputStream out)
           throws IOException

Writes BufferedImage as Baseline JPEG to an OutputStream

This method does not close the provided OutputStream after the write operation has completed; it is the responsibility of the caller to close the stream.

Parameters:

image - BufferedImage The image to write

out - The stream to write to

Throws:

IOException - if the image wasn't written

setQuality

public void setQuality(int quality)

Set the image quality level for JPEG output. The quality level can be between 1 - 100 and if not set defaults to 50. Higher quality produces better quality JPEG files but increases output data size.

Parameters:

quality - Quality level to set for JPEG output

getQuality

public int getQuality()

Retrieve the image quality level for JPEG output. The quality level can be between 1 - 100 and if not set defaults to 50. Higher quality produces better quality JPEG files but increases output data size.

Returns:

Quality level used for JPEG output
