1997.06.16 17:17 "TIFF library", by Ivo Welch
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
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?
