Ladies and Gentlemen:

It is rare that I complain about something that is free, but the fact
that this TIFF library lacks the ability to do a
	TiffWriteRGBAImage()
that corresponds to the ReadRGBAImage() is an unforgivable omission.  I
have spent the weekend trying to fiddle with writing a routine that
reads an image, draws a diagonal through it, and writes back a new
image.  I never succeeded.

Now, I have figured out how to read/write an encoded strip into raw bit
patterns in memory (from tiffcp.c---incidentally a 20 page program I had
to go through for this simple information).  But I could not find a
function that translates the memory bit pattern into an RGBA image and
back, so I could not do simple image manipulation.  Grrr!

Now, I understand that this function might be involved (e.g., to write
BW images from an RGBA image), but do users really have to spend a month
to do the most simple tasks with this TIFF library?
