How do I get the x,y coords from the result of where?
Here's what I did:
IDL> t = where(slice eq max(slice))
IDL> print,slice(t)
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28 28 28 28 28 28 28
28 28 28
IDL> print,size(slice)
2 256 256 2 65536
IDL> y = t/255
IDL> x = t - (y*255)
IDL> print,slice(x,y)
0 0 0 0 0 0 10 10 10
11 9 10 0 10 10 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0
I also tried
IDL> print,slice(y,x)
0 0 0 0 0 0 0 0 0
0 0 0 0 12 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 10 11 19
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 10 0 0
0 10 0
IDL> print,max(slice)
28
