How can I display the image (pixel data) of the different directories inside a single tiff file?
I have several tiff-based files (of format ndpi, svs, bif, etc these are digital pathology images) each of which contain a pyramidal-like structure of Image File Directories. When I run tiffinfo or tiffdump on these images I am informed of the different directories present. e.g.
when running tiffinfo my_file I get the following output
TIFF Directory at offset 0x898b0f0 (144224496)

How can I now use a Python library to visually inspect the images of each TIFF directories?
