Hi,

i'm searching for an example for 2d linear interpolation.
The data is in an array unsigned char [10][400].

Here is my "worksheet", may be, it help's to explain for i looking on:

There is the way to solve  the prob. for x-value 55 and y-value 800 = 59,35

I need no floting point, unsigned char is only what i need.

Best regards, Rolf
