Method Detail

updateMetadata

protected IIOMetadata updateMetadata(RenderedImage image,
                                     IIOMetadata meta,
                                     ImageWriterParams params)

Updates the metadata information based on the parameters to this writer.

Overrides:

updateMetadata in class ImageIOImageWriter

Parameters:

image - the current image being rendered

meta - the metadata

params - the parameters

Returns:

the updated metadata

createShortMetadataNode

public static final IIOMetadataNode createShortMetadataNode(int number,
                                                            String name,
                                                            String value)

Utility to create a TIFFShort metadata child node of a TIFFShorts node for TIFF metadata.

Parameters:

number - value of the number attribute of the TIFField

name - value of the name attribute of the TIFFField

value - value of the value attribute of the TIFFShort

Returns:

the new metadata node

createShortMetadataNode

public static final IIOMetadataNode createShortMetadataNode(int number,
                                                            String name,

                                                            String description)

Utility to create a TIFFShort metadata child node of a TIFFShorts node for TIFF metadata.

Parameters:

number - value of the number attribute of the TIFField

name - value of the name attribute of the TIFFField

value - value of the value attribute of the TIFFShort

description - value of the description attribute of the TIFFShort, ignored if null

Returns:

the new metadata node

createRationalMetadataNode

public static final IIOMetadataNode createRationalMetadataNode(int number,
                                                               String name,
                                                               String value)

Utility to create a TIFFRational metadata child node of a TIFFRationals node for TIFF metadata.

Parameters:

number - value of the number attribute of the TIFField

name - value of the name attribute of the TIFFField

value - value of the value attribute of the TIFFRational

Returns:

the new metadata node

createMetadataField

public static final IIOMetadataNode createMetadataField(int number,
                                                        String name)

Utility function to create a base TIFFField node for TIFF metadata.

Parameters:

number - value of the number attribute of the TIFField

name - value of the name attribute of the TIFFField

Returns:

the new metadata node

createStreamMetadata

protected IIOMetadata createStreamMetadata(ImageWriter writer,
                                           ImageWriteParam writeParam,
                                           ImageWriterParams params)

Creates the stream metadata for image. By default, this method returns null which causes the default stream metadata to be used. Subclasses can override this to supply special stream metadata (see TIFF for an example).

Overrides:

createStreamMetadata in class ImageIOImageWriter

Parameters:

writer - the image write

writeParam - the ImageIO write parameters

params - the ImageWriter write parameters

Returns:

the stream metadata (or null if no special metadata needs to be produced)
