Correct Syntax to get image subtitle in python scripting language

[GP]

Hie!

I am attempting to convert my .ijm script to python/jython and am a super beginner in the field.

In the script I extract subtitle of one the images in a step by using :: getMetadata("Label") command but am unable to find the correct syntax to use it in python script.
I tried the other mentioned subtitle commands as well : getInfo("image.subtitle") etc as by adding prefix 'IJ.run' or 'imp.' as follows::

imp = IJ.getImage()
IJ.run (imp, getMetadata("Label") or
subtitle = imp.getMetadata("Label")

Please let me know about the correct way to perform this action or if any specific library needs to be downloaded to do so. It works perfect for imp.getTitle() command.
I was not able to find the answer to it please redirect me if the question has been solved earlier.

Thanks a lot!

Unfortunately, macro functions do not always have a direct corollary in the
Java/scripting API.

What you can do is read the code which defines how the macro language
functions work. In the case of getMetadata, it is here:


https://github.com/imagej/ImageJA/blob/v1.51k/src/main/java/ij/macro/Functions.java#L3715-L3740

In this case, we can see several calls which might do the trick for you:

  metadata = imp.getProperty("Label");
  metadata = imp.getProperty("Info");
  metadata = imp.getStack().getSliceLabel(imp.getCurrentSlice());
