Creating a TIFF 16bit image as result of a math expression
Posted: 2008-02-01T07:59:40-07:00
Dear IM users. This is the problem I am facing. I thought it would be possible to solve using IM but so fare I was not able to do it.
I need a TIFF16 for assigning each pixel the elevation value of a Tsunami wave. The real world elevation values are calculated using a math expression acting over pixel values of other three 8 bits images.
I used convert and everithing works fine but the normalisation of the value of the pixel value into the final result. Is there a way to disable the process of normalisation so that the final pixel value reflect the result of the expression?
Any other idea to accomplish this task?
Thanks everybosy
