JPEG2000 Converter
The JDeli Java image conversion library is able to open and export images as JPEG2000 files, giving a complete bulk JPEG2000 converter between JPEG2000 file format and lots of other image file formats.
JDeli can do this in ONE step with the convert method or separately open and export the JPEG2000 image.
Batch Convert images to JPEG2000 from Command Line or other language
java -jar jdeli.jar --convert jpx "inputFileOrDir" "outputDir"
Convert into JPEG2000 or from a JPEG2000 image file in Java
JDeli.convert(File inFile, File outFile);
JDeli.convert(InputStream inFile, OutputStream outfile, String format);
byte[] outputData=JDeli.convert(byte[] inputData, String format);
An additional set of methods allow values to be passed in which can give more control over conversion, depending on the image formats being converted (ie different image compression options).
