JDeli is able to convert a JPEG2000 image into a PDF file.
JDeli can do this in ONE step with the convert method. You can also do this by reading a JPEG2000 image and then writing out the image as PDF, which is useful if you want to process the image in some way.
Single step method to convert from JPEG2000 into PDF file
JDeli.convert(File inFile, File outFile);
JDeli.convert(InputStream inFile, OutputStream outfile, String format);
byte outputData = JDeli.convert(byte inputData, String format);
Depending on the image formats being converted (ie set compression level in Tiff files), JDeli also provides overloaded methods. These can be used to supply conversion options for more control over the conversion process.
Read / Write methods for converting from JPEG2000 into PDF file
1. Read JPEG2000 image into Java
BufferedImage image = JDeli.read(imageFile);
Jpeg2000Decoder decoder = new Jpeg2000Decoder();
BufferedImage image = decoder.read(imageData);
2. Process image
3. Write out Java image as PDF
File myFile = new File("file.pdf"); JDeli.write(image, "pdf", myFile);
PdfEncoder encoder = new PdfEncoder();
