I created a bunch of screenshots in the GIMP and saved them as compressed TIFFs using the LZW compression. I brought these over to my Mac where I was working on putting them into another program. Checking to make sure things worked correctly, I opened them up in a couple different graphics programs, one of which was GraphicConverter. Needless to say, GraphicConverter (and the other graphics programs I tried) couldn't open the file, or it would just display as virtually all black and some noise. I sent a note and a copy of one image off to the author and received the following information back from him: > I found the problem with the TIFF file. > This is the first LZW compressed TIFF with FillOrder=2 (the Adobe TIFF specs > do normally not allow this!). Is this a bug? should the LZW compression be changed so that it conforms to standard? -- Carl B. Constantine DuckWing
