NAME
squareRoot - take the square root of each pixel value
SYNTAX
#include <
xite/arithmetic.h>
int squareRoot( IBAND input, IBAND output,
double scale );
DESCRIPTION
squareRootplaces the square root of the input bandinto the output band:
output(x,y) = sqrt(input(x,y)) * scale
Only the largest rectangle common to the two bandsis handled.
Accepts all pixel types except complex and double complex.Input and output must have the same pixel type, otherwise useconvertBiff.
If the result is outside the domain of the actual pixel type,the nearest possible value is returned.
Identical arguments for input and output are allowed.
RETURN VALUE
0 => ok
1 => Illegal combination of pixel types
2 => Illegal pixel type
