Hello,
I have problem digitalizing an image (which is vertcally depth related, meaning that one line of pixels is assigned to a one depth point) into pixels and then assigning a colour map to the resulting pixels with values between 0 (white) to 6 (black).
Please see the colour scale with values between 0 and 6.

And a depth related (vertically) image (one box has 50 m; here 150 m interval is shown).

I tried image digitalizers, but they work mainly for graphs with lines, and this seems to be more complicated case. I am very thankful for any kind of help.

Try imquantize() if you want ot quantize your continuous depths into ranges of uniform depths.
Try creating a custom colormap and then using colormap() and colorbar() if you want certain colors to appear at certain depths. You can also use caxis().
