Retrieve full metadata from Dataset

radoslaw.ejsmont · October 30, 2017, 11:03am

Hi folks,

I am reading some FV1000-format files using IOService. I would like to do some checks on metadata to make sure images are sane (check optical path, lasers, etc.). In ImageJ1 API I can use “Show Info” to ket key-value pairs for metadata, however in IJ2 would when using dataset.getProperties() I only get stripped down version of metadata. How do I get access to full metadata from a Dataset?

Thanks,

R.

Hi @radoslaw.ejsmont,

have a look at this current PR in tutorials by @brossetti:

https://github.com/imagej/tutorials/pull/45

specifically, these lines might help getting you started:

// determine the Format based on the extension and, if necessary, the source data
Format format = formatService.getFormat(filePath);


// create an instance of the associated Parser and parse metadata from the image file
Metadata metadata = format.createParser().parse(filePath);


// use FieldPrinter to traverse metadata tree and return as a String
String metadataTree = new FieldPrinter(metadata).toString();


// (optional) remove some of the tree formatting to make the metadata easier to read
mString = formatMetadata(metadataTree);
