Sorry for the delay in my reply.
The reason getRangeSets is missing is because TiffForm returns image
planes as ImageFlatFields (which are FlatFields backed by Java
BufferedImages), and ImageFlatField does not implement getRangeSets.
However, I would be surprised if you need this functionality for what
you describe, since my understanding is that you are looking for the X
and Y resolution of your image planes (i.e., number of rows and
columns), which is stored as part of the domain set.
It sounds like what you want to do is load a TIFF file, then visualize
it. The easiest way to do so is to let VisAD autoscale your X and Y
axes based on the data. You can check out the testRead method of
visad.data.bio.LociForm for an example of how to do it, or see it in
action by running:
java visad.data.tiff.TiffForm /path/to/my/data.tiff
If you need it, here is some code to extract number of rows and
columns from a single-page TIFF file:
TiffForm tiffForm = new TiffForm();
FlatField data = (FlatField) tiffForm.open("/path/to/my/data.tiff");
GriddedSet domainSet = (GriddedSet) data.getDomainSet();
int len = domainSet.getLengths();
System.out.println("TIFF image is " + len + " x " + len + " pixels.");
If I have misunderstood your question and you do need the getRangeSets
method with ImageFlatField, let me know and I can implement it for
you. And please do not hesitate to ask if you have any further
questions about VisAD.
