I want to check whether an image is tiled or striped? Is there a function to
check this in libtiff?

When I do
  TIFFGetField(tif, TIFFTAG_TILEWIDTH, &tileWidth);
  TIFFGetField(tif, TIFFTAG_TILELENGTH, &tileLength);
They return very big nos. (1075531856, 1075536024) but not a -1 etc.

Maybe I could do a check:
if (tileLength > 1024 || tileWidth > 1024)
/* This is a striped image */

But I don't know whether that's guaranteed to be such a big +ve no. or -ve
no.

So can somebody advise what's the most appropriate way to check this?
