Method Detail

setCompressionType

public static void setCompressionType(javax.imageio.ImageWriteParam param,
                                      java.awt.image.BufferedImage image)

Sets the ImageIO parameter compression type based on the given image.

Parameters:

image - buffered image used to decide compression type

param - ImageIO write parameter to update

updateMetadata

static void updateMetadata(javax.imageio.metadata.IIOMetadata metadata,
                           java.awt.image.BufferedImage image,
                           int dpi)
                    throws javax.imageio.metadata.IIOInvalidTreeException

Updates the given ImageIO metadata with Sun's custom TIFF tags, as described in the org.apache.xmlgraphics.image.writer.imageio.ImageIOTIFFImageWriter sources, the com.sun.media.imageio.plugins.tiff package javadoc and the TIFF specification.

Parameters:

image - buffered image which will be written

metadata - ImageIO metadata

dpi - image dots per inch

Throws:

javax.imageio.metadata.IIOInvalidTreeException - if something goes wrong
