Method Detail

createStreamAdapter

public static java.io.InputStream createStreamAdapter(javax.imageio.stream.ImageInputStream pStream)

Creates an InputStream adapter that reads from an underlying ImageInputStream. The input stream will read until the end of pStream.

Parameters:

pStream - the stream to read from.

Returns:

an InputStream reading from pStream.

createStreamAdapter

public static java.io.InputStream createStreamAdapter(javax.imageio.stream.ImageInputStream pStream,
                                                      long pLength)

Creates an InputStream adapter that reads from an underlying ImageInputStream. The input stream will read until the end of pStream, or at most pLength bytes has been read.

Parameters:

pStream - the stream to read from.

pLength - the maximum number of bytes that can be read from pStream.

Returns:

an InputStream reading from pStream.

createStreamAdapter

public static java.io.OutputStream createStreamAdapter(javax.imageio.stream.ImageOutputStream pStream)

Creates an OutputStream adapter that writes to an underlying ImageOutputStream.

Note: The adapter is buffered, and MUST be properly flushed/closed after use, otherwise data may be lost.

Parameters:

pStream - the stream to write to.

Returns:

an OutputSteam writing to pStream.

                                                 int pSrcWidth,
                                                 int pSrcHeight)

fakeAOI

public static java.awt.image.BufferedImage fakeAOI(java.awt.image.BufferedImage pImage,
                                                   java.awt.Rectangle pSourceRegion)

getProviderInfo

public static ProviderInfo getProviderInfo(java.lang.Class<? extends javax.imageio.spi.IIOServiceProvider> pProviderClass)

Creates a ProviderInfo instance for the given service provider.

Parameters:

pProviderClass - the provider class to get info for.

Returns:

the newly created ProviderInfo.

deregisterProvider

public static <T> void deregisterProvider(javax.imageio.spi.ServiceRegistry pRegistry,
                                          javax.imageio.spi.IIOServiceProvider pProvider,
                                          java.lang.Class<T> pCategory)

Deprecated.

THIS METHOD WILL ME MOVED/RENAMED, DO NOT USE.

Parameters:

pRegistry - the registry to unregister from

pProvider - the provider to unregister

pCategory - the category to unregister from

getNormalizedReaderFormatNames

public static java.lang.String[] getNormalizedReaderFormatNames()

Returns a sorted array of format names, that can be read by ImageIO. The names are all upper-case, and contains no duplicates.

Returns:

a normalized array of Strings.

ImageIO.getReaderFormatNames()

getNormalizedWriterFormatNames

public static java.lang.String[] getNormalizedWriterFormatNames()

Returns a sorted array of format names, that can be written by ImageIO. The names are all upper-case, and contains no duplicates.

Returns:

a normalized array of Strings.
