Hello all,

pleaseplease help me!
Quite new on idl and just wondering is there a simple way to move
individual pixels within an image?

For example a function

output = indishift(input, tx,ty)

where input,tx and ty are same size arrays and e.g if in pixel
location (30,30) tx has a value 5 and ty has a value 0, then output
has the same value on (30,30) as the input image PLUS the pixel value
from input image (35,30).

So tx contains the shifts in x direction and ty in y direction.

Thanks alot for any help!!!
