- All Implemented Interfaces:
ImageDecoder
public class TIFFImageDecoder extends ImageDecoderImpl
A baseline TIFF reader. The reader has some functionality in addition to the baseline specifications for Bilevel images, for which the group 3 and group 4 decompression schemes have been implemented. Support for LZW decompression has also been added. Support for Horizontal differencing predictor decoding is also included, when used with LZW compression. However, this support is limited to data with bitsPerSample value of 8. When reading in RGB images, support for alpha and extraSamples being present has been added. Support for reading in images with 16 bit samples has been added. Support for the SampleFormat tag (signed samples as well as floating-point samples) has also been added. In all other cases, support is limited to Baseline specifications.

getNumPages
public int getNumPages() throws java.io.IOException
Description copied from class:ImageDecoderImpl
Returns the number of pages present in the current stream. By default, the return value is 1. Subclasses that deal with multi-page formats should override this method.- Specified by:
getNumPages
in interfaceImageDecoder
- Overrides:
getNumPages
in classImageDecoderImpl
- Throws:
java.io.IOException
-
decodeAsRenderedImage
public java.awt.image.RenderedImage decodeAsRenderedImage(int page) throws java.io.IOException
Description copied from class:ImageDecoderImpl
Returns aRenderedImage
that contains the decoded contents of theSeekableStream
associated with thisImageDecoder
. The given page of a multi-page image is decoded. If the page does not exist, an IOException will be thrown. Page numbering begins at zero.- Specified by:
decodeAsRenderedImage
in interfaceImageDecoder
- Specified by:
decodeAsRenderedImage
in classImageDecoderImpl
- Parameters:
page
- The page to be decoded.- Throws:
java.io.IOException
