---------------------------------
Hi [~tilman], thanks for the response, can you give some more details? Since
the doc to image conversion is done by this single pdfBox API:
renderer.renderImageWithDPI(0, dpi, ImageType.RGB)
I am not clear where to add the decoding step using the jpeg2000 decoder.
Or are you suggesting us to add jpeg2000 into our dependency/class path (we are
using gradle to manage dependency), then pdfbox will be able to automatically
use the correct decoder?
Thanks!

> Hi team,
> We noticed drastic color change after performing a PDF to image conversion.
> The API we used is something like:
> {code:java}
> PDFDocument document = PDDocument.load(xxx);
> PDFRenderer renderer = new PDFRenderer(document);
> renderer.renderImageWithDPI(0, dpi, ImageType.RGB); {code}
> The original pdf and the processed output image is attached to the ticket.
> The pdfbox version we are using is 2.0.27
