Java Advanced Imaging API
What is Java Advanced Imaging?Image I/O IssuesDownloadFAQInterest GroupDocumentationSuccess
Overview
I suggest first copy JAI libray to another destination and remove them from Java instalation folder: jaicodec-1.1.3.jar jaicore-1.1.3.jar jaiimageio-1.1.jar. Geoserver has the same librarys and it. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 14? If you want to continue to develop with Java 6 using command-line, then you can modify the startup script for your favorite command environment.
An important adjunct to the Java Advanced Imaging (JAI) API is a set of image encoder/decoder (codec) classes, which have been packaged with JAI since the release of JAI 1.0. The encoders and decoders for several popular image storage formats have been implemented. The image formats supported by these ancillary codec classes are: BMP, GIF (decoder only), FlashPix (decoder only), JPEG, PNG, PNM, TIFF, and WBMP.
However, the actual codec classes are not a committed part of JAI, and they are released under the com.sun.media.jai.codec
and com.sun.media.jai.codecimpl
packages. This means the codec classes might change in the future at the discretion of the JAI developers. Software developers should take this into consideration when writing any code directly against these classes.
The preferred method for reading an image file of any format into a RenderedImage
is:
RenderedImage
Many questions have been posted to the JAI mailing lists regarding each specific file format, and below are answers to some commonly raised issues. In addition, please read the JAI FAQ page for more answers to Image I/O related questions.
BMP
The Windows 95 version of BMP is supported. The bit depth of the encoded output is determined by that of the source image.
FlashPix
The decoder is only partially implemented. No encoder is available at this time.
GIF
The decoder supports animated GIF files and GIF files with transparent background. Only the first frame of an animated GIF file may be loaded via JAI; subsequent frames must be obtained via direct use of the ancillary codec classes.
JPEG
The JPEG support is currently implemented on top of the unofficial J2SE classes in the com.sun.image.codec.jpeg
package, which may not exist in all Java 2 environments.
PNG
The PNG encoder automatically determines the type of the image to be encoded (RGB, Grayscale, or Palette) based on the source image. The PNGEncodeParam
setting has no effect on this.
PNM
PNM files may either have ASCII or raw (binary) data. The decoder automatically determines the data format and reads the data accordingly. By default the encoder stores the image data in raw format whenever possible. To request that the encoder store the data in ASCII format in JAI 1.0.2 or later, use the following encoder parameter argument:
TIFF
In addition to the baseline specification, the encoder and decoder support PackBits, modified Huffman and CCITT bilevel encodings (fax), JPEG-in-TIFF (per TIFF Technical Note #2), and DEFLATE compression schemes, can handle images with 16- and 32-bit integral samples and 32-bit floating point samples, and can read and write tiled images of all supported data types. The decoder in addition can decompress LZW-compressed imagery.
Additional features may be addressed in the future.
A single page of a multi-page TIFF file may loaded most easily by using the page
parameter with the 'TIFF' operator which is documented in the class comments of javax.media.jai.operator.TIFFDescriptor
. A code sample is included here to show a means of loading a single page of a multi-page TIFF file using the ancillary codec classes directly.
WBMP
The WBMP codec reads and writes images in the Wireless Bitmap format described in chapter 6 and Appendix A of the Wireless Application Protocol (WAP) Wireless Application Environment Specification, Version 1.3, 29 March 2000. The WBMP type supported is WBMP Type 0: B/W, Uncompressed Bitmap. There are no limitations on the image dimensions.
The Java Image I/O API
Due to the many requests for a comprehensive image I/O package the Java Image I/O API was developed. The Java Image I/O API is part of the Java TM 2 Platform, Standard Edition, version 1.4 (J2SE1.4).
The Future of Image I/O in JAI
A package set called JAI-Image I/O Tools has been released and is available via the JAI home page. The package set includes image reader and writer plug-ins for the Java Image I/O API for numerous formats, image streams which use the Java New I/O API, and JAI operations for reading and writing images using the Java Image I/O API.
In a future JAI release, the image I/O-related operators in JAI-Image I/O Tools will be propagated to JAI. It has not been definitively determined as yet, but it is likely that when the new I/O operators have been added to JAI the old operations will be deprecated.
The classes currently in the com.sun.media.jai.codec
and com.sun.media.jai.codecimpl
packages will most likely be removed concurrent with a JAI release subsequent to that in which the Java Image I/O API-based operators become available. However, Sun is making publicly available the source code of the com.sun.media.jai.codec
and com.sun.media.jai.codecimpl
classes so that developers who have written code based on them will still be able to use them. Please note that no technical support may be provided for these classes once they have been superseded by the Java Image I/O API.
Yesterday, I updated my MacBook Pro from macOS HS to macOS Mojave.
When I checked my Java version (10.0.2), the pane reported that it was outdated:
I clicked the Update Now button and some routine was started. At the end, I was asked whether I wanted to remove old Java versions, which I confirmed.
To my big surprise, Java was completely removed from the System Preferences pane. So I decided to re-install Java 10 manually.
As it turned out, Java 10 has been deprecated, so instead, I downloaded Java 11 from Oracle.
I ran the set up routine for Java 11 (twice), but to no avail: no Java was installed on my MacBook Pro.
(In the end I installed jre-10.0.2_osx-x64_bin.dmg from https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase10-4 425482.html, just to have Java 10.0.2 working again.)
So my question is: How to install Java 11 on macOS Mojave?
Java 10.0.2 is installed.
