Is there a way in MATLAB 7.10 (R2010a) to find out if the "Tag" for a TIFF file is empty?

Asked by Prabhakar on 18 Jan 2011
I am using the getTag function in the Tiff class to query the "Tag" field. The function works fine. But if the Tag is empty, my code terminates with an error. I want to know if there is a way to find out if the field is empty, and if it is not, then query its contents.

There is no direct way to use the Tiff object to query whether the Tag field is present or not. This is because the Tiff object is really just a thin wrapper around the libtiff library, which does not offer a function for inquiring as to whether a tag is present. One finds out only by asking for the value, and this means one would have to use try/catch with getTag on the Tiff object.
