jai-imageio-core (standalone)

NOTE: This is a community fork of the original java.net project jai-imageio-core (which is no longer available upstream).

This project adds read/write support for the following file types to Java's ImageIO:

wbmp
bmp
pcx
pnm
raw
tiff
gif (write)

Note that most of these formats are now supported by Java 9.

The classes of this projects are not generally used directly, but through the SPI plugin mechanism of ImageIO. See the ImageIO guide for details.

The implementations provided by this project use the package name com.github.jaiimageio, note that other implementations might be provided by your Java installation or other dependencies.

This project is called 'standalone' as unlike the original jai-imageio-core it has removed dependencies to jai-core packages (javax.media.jai) and JPEG 2000 (jj2000). This version also does not include the C implementations from libJIIO, meaning that this version is platform independent and fully redistributable under the 3-clause BSD license in LICENSE.txt (and thus is Apache and GPL compatible).

JPEG 2000 support is available as an additional module jai-imageio-jpeg2000 as it has a different (non-GPL compatible) license.

If you are not concerned about GPL compatibility or source code availability, you may want to check out https://github.com/geosolutions-it/imageio-ext/ which is actively maintained and extends the original imageio with many useful features, but depends on the binary distribution of jai_core.
