Java TM 2D Bugs Affecting the Java TM Advanced Imaging API
These are known Java TM 2D bugs which may cause problems using JAI or be manifested via JAI.
- The
isCompatibleSampleModel()method injava.awt.image.ComponentColorModelmanifests different bugs in different versions of Sun Microsystems' J2SE. In J2SE 1.2 it returnsfalseif theSampleModelis aComponentSampleModelwhich is the opposite of what it should do. This renders J2SE 1.2* unusable with JAI 1.1 or greater. In J2SE 1.3, it does not verify that the number ofSampleModelbands matches the number ofColorModelcomponents. This latter problem has been fixed in J2SE 1.4.
Additional Problems/Limitations of Note
These are items which are not bugs per se. Some of this information is duplicated from the README page.
Codecs
- TIFF Codec
Java Advanced Imaging 1.1.2_01 TIFF codec supports a large portion of the TIFF specification including baseline TIFF and several extensions. The implementation does however have the following limitations:
- The TIFF encoder does not support LZW compression.
- Planar format (PlanarConfiguration field has value 2) is not supported for decoding or encoding.
- BMP Codec
- Only the default RGB color space is supported.
- Alpha channels are not supported by the BMP encoder.
- The BMP encoder supports only version 3, i.e., does not support versions 2 or 4. This is despite the fact that the desired version number may be set via
BMPEncodeParam.setVersion()and thatBMPEncodeParamdefines the constantsVERSION_2andVERSION_4.
Applets

Automatic installation does not work with Java TM Plug-In versions prior to 1.3.1.
