I've got an issue with scaling the tiff images to their original size
if just the DPI resolution of the x and y axes are given. Could you
please point me to a How-To or explain it?

x resolution: 203 DPI
y resolution: 98 DPI
The tiff image is a byte[]

If you want to give me an example: I'm using Java.
Thank you in advance!

That's impossible without further info. – Fildor Feb 21 '13 at 14:31
Which Info do you need? – synner Feb 21 '13 at 14:35
You'll have to know how many dots you have in x and y ... if you cannot find that out, you can only make educated guesses. – Fildor Feb 21 '13 at 14:36
Okay wait a sec, I'll edit :)! – synner Feb 21 '13 at 14:37
After edit: What unit is this? pixels? dots per inch? In what form do you have the image? byte[] or ImageObject ... – Fildor Feb 21 '13 at 14:41
DPI and it is a byte[], edited it - thank you. – synner Feb 21 '13 at 14:43
Have you been able to decode it and display in any size? – Fildor Feb 21 '13 at 14:46
Do you know about JAI? http://www.oracle.com/technetwork/java/javase/tech/jai-142803.html – Fildor Feb 21 '13 at 14:50
