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?

Pushkar,

Call TIFFIsTiled(tif). If it returns a non-zero value the file is tiled, otherwise stripped.

Best regards,
