Support to read metadata from JPEG2000 files

[albfernandez]

Please add support to read metadata from JPEG2000 files.

Sample image relax.jp2 relax.zip attached (downloaded from https://www.fnordware.com/j2k/jp2samples.html)

Sample code:

File file = new File("relax.jp2");
try (InputStream is = new FileInputStream(file)) {
    Metadata metadata = ImageMetadataReader.readMetadata(is, file.length());
}

May I be assigned to this issue to implement this feature?

[drewnoakes]

@Hsstone1 thank you for volunteering. There is no need to be assigned before you start working on the feature, though it's a good idea to declare you intention to avoid duplication of effort. In this case I believe you are in the clear.

Reach out here if you have any questions.

[drewnoakes]

Once you have completed your analysis, if you'd like to share your thinking then we can validate your approach. This may save you some time overall.

@drewnoakes : Thanks for your work on this great library!

Is there any news regarding the support of JPG2000 files? Thank you.

[drewnoakes]

No news. It will likely require someone who needs this support to implement it.
