If I use TIFFOpen and TIFFReadRGBA Image, am I a baseline TIFF reader only or do I support extensions?

You will support extensions. For example, Group4 compression, LZW compression, JPEG compression, Zip compression, tiled TIFF, and likely many other valuable features are officially extensions.

If I support extensions, what can I do to only be a Baseline TIFF Reader? Is there a macro or a define on what to support?

I apologize if my questions would seem insensible. I just want to ask everything just to make sure. Thanks!

Your question is insensible. :-)

If you want to disable capabilities, you should use libtiff's lower-level interfaces and choose not to implement non-baseline features. Presumably libtiff itself can be edited to disable many features.
