Constructor Detail

JPEGCodec

public JPEGCodec()

Constructor for the JPEGCodec object

Method Detail

getFormatName

public java.lang.String getFormatName()

Gets the FormatName attribute of the JPEGCodec object

---

getEncodeParamClass

public java.lang.Class getEncodeParamClass()

Gets the EncodeParamClass attribute of the JPEGCodec object

---

getDecodeParamClass

public java.lang.Class getDecodeParamClass()

Gets the DecodeParamClass attribute of the JPEGCodec object

---

getNumHeaderBytes

public int getNumHeaderBytes()

Gets the NumHeaderBytes attribute of the JPEGCodec object

---

isFormatRecognized

public boolean isFormatRecognized(byte[] header)

Gets the FormatRecognized attribute of the JPEGCodec object

---

canEncodeImage

public boolean canEncodeImage(java.awt.image.RenderedImage im,
                              non_com.media.jai.codec.ImageEncodeParam param)

Description of the Method

---

createImageEncoder

protected non_com.media.jai.codec.ImageEncoder createImageEncoder(java.io.OutputStream dst,
                                                                  non_com.media.jai.codec.ImageEncodeParam param)

Description copied from class: non_com.media.jai.codec.ImageCodec

In a concrete subclass of ImageCodec, returns an implementation of the ImageEncoder interface appropriate for that codec.

---

createImageDecoder

protected non_com.media.jai.codec.ImageDecoder createImageDecoder(java.io.InputStream src,
                                                                  non_com.media.jai.codec.ImageDecodeParam param)

Description copied from class: non_com.media.jai.codec.ImageCodec

Returns an implementation of the ImageDecoder interface appropriate for that codec. Subclasses of ImageCodec may override this method if they wish to accept data directly from an InputStream ; otherwise, this method will convert the source into a backwards-seekable SeekableStream and call the appropriate version of createImageDecoder for that data type.

Instances of ImageCodec that do not require the ability to seek backwards in their source SeekableStream should override this method in order to avoid the default call to SeekableStream.wrapInputStream(src, true) .

createImageDecoder

protected non_com.media.jai.codec.ImageDecoder createImageDecoder(java.io.File src,
                                                                  non_com.media.jai.codec.ImageDecodeParam param)
                                                           throws java.io.IOException

Description copied from class: non_com.media.jai.codec.ImageCodec

Returns an implementation of the ImageDecoder interface appropriate for that codec. Subclasses of ImageCodec may override this method if they wish to accept data directly from a File ; otherwise, this method will convert the source into a SeekableStream and call the appropriate version of createImageDecoder for that data type.

createImageDecoder

protected non_com.media.jai.codec.ImageDecoder createImageDecoder(non_com.media.jai.codec.SeekableStream src,
                                                                  non_com.media.jai.codec.ImageDecodeParam param)

Description copied from class: non_com.media.jai.codec.ImageCodec

In a concrete subclass of ImageCodec, returns an implementation of the ImageDecoder interface appropriate for that codec.
