Package javax.imageio
This package provides image input/output APIs.
| IIOParamController | An interface to set image parameters. |
| ImageTranscoder | An ImageTranscoder translates IIOMetadata objects provided by an
ImageReader into corresponding IIOMetadata objects that can be
understood by a given ImageWriter.
|
| IIOImage | IIOImage is a container class for components of an image file that
stores image data, image metadata and thumbnails.
|
| IIOParam | An IIOParam stores parameters used when encoding or decoding image
streams. |
| ImageIO | An uninstantiable class that provides static methods for locating
and using image readers and writers.
|
| ImageReader | A class for decoding images within the ImageIO framework.
|
| ImageReadParam | DOCUMENT ME
|
| ImageTypeSpecifier | ImageTypeSpecifier store the color and sample models associated
with an IIOImage.
|
| ImageWriteParam | DOCUMENT ME
|
| ImageWriter | A class for encoding images within the ImageIO framework.
|
| IIOException | A runtime exception to indicate image reading and writing failures.

This package provides image input/output APIs.
The standard class library provides other ways of loading images (@see
java.awt.Toolkit, @see java.awt.Component)) but the ImageIO package is
more powerful.
The static ImageIO class supports reading and writing images in many
different formats along with most other basic image I/O operations.
Other classes provide finer control of image-related operations;
reading is controlled by ImageReader, ImageReadParam and
ImageTypeSpecifyer, writing by ImageWriter and ImageWriteParam.
ImageTranscoder allows fine-grained control over how images are
converted between formats and IIOException reports errors. IIOImage
describes an image file in detail including metadata and thumbnails.
Supported Formats
The default GNU Classpath ImageIO backend uses ImageMagick and so
supports the following formats:
| Read | Write |

| JPEG | yes | yes |
| PNG | yes | yes |
| BMP | yes | yes |
| WBMP | yes | yes |
| GIF | yes | yes |
