People seem perfectly capable	dealing with these others.  Dealing with the format of TIFF	is frankly less difficult than dealing with the DCT, LZW, and	FAX encoding of the image data.  The majority of the libraries	which deal with TIFF are dedicated to these other issues rather	than with simply decoding the tags and parameters.	Perhaps people are overwhelmed in comparison with some rather	simpleminded formats such as GIF, PCX, and BMP, but to suggest	that TIFF is so complex as to be doomed to failure is ludicrous.	That doesn't mean that GIF isn't fine, but don't even thing about	using it in many instances.  GIF is very nice for use in low-end	photos applications and for screen grabs and such, but it would	never do for high-volume or high-resolution systems.  FAX is nice,	but it doesn't do color (and GIF doesn't do B&W all that well).	JPEG is nice for high-resolution color, but is slow for low-end.	The advantage TIFF brings to the table is its ability to handle	all these situations (and then some).  Naturally it's more complex.	But I'ld rather propose TIFF imaging solutions over imaging	systems based on having to deal with 3-4 file formats anyday.	You may find that TIFF is too complicated for your personal tastes	but please don't wrail against it's complexity.  The complexity	it contains is required to provide the functionality it does and	doesn't come close to the complexity found in most commercially	viable file formats.	If we're in philosophical arguments against complexity, let's all	go program in scheme and forth and do imaging with run length	encoding.
