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.

fakeSubsampling

public static java.awt.Image fakeSubsampling(java.awt.Image pImage,
                             javax.imageio.IIOParam pParam)

getSourceRegion

public static java.awt.Rectangle getSourceRegion(javax.imageio.IIOParam pParam,
                                 int pSrcWidth,
                                 int pSrcHeight)

fakeAOI

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

deregisterProvider

public static <T> void deregisterProvider(javax.imageio.spi.ServiceRegistry registry,
                          javax.imageio.spi.IIOServiceProvider provider,
                          java.lang.Class<T> category)

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

Parameters:

registry - the registry to unregister from.

provider - the provider to unregister.

category - the category to unregister from.

lookupProviderByName

public static <T> T lookupProviderByName(javax.imageio.spi.ServiceRegistry registry,
                         java.lang.String providerClassName,
                         java.lang.Class<T> category)

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

Parameters:

registry - the registry to lookup from.

providerClassName - name of the provider class.

category - provider category

Returns:

the provider instance, or null.

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.

See Also:

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.
