SYNTAX
linearTrans [-log] -wf <weight_file> <inimage> <outimage>
linearTrans [-log] <inimage> <outimage> <weight>...
DESCRIPTION
Performs a linear transformation from
inimageto
outimageaccording to specified weights. Everypixel (seen as a vector through all bands) becomesa linear combination of the elements of input pixelvector.
The total number of weights should equal the square of thenumber of bands in the images.
OPTIONS
- -wf weight_file
- The weights may be given in the command (using theweightsargument), or in a file with the -wf option.
- -log
- The number of underflows and overflows are written tostderr.
RESTRICTIONS
The bands of
inimagemust have pixel type unsigned byte.All the input bands in
inimageshould have the same size.
RETURN VALUE
0 if ok, 1 otherwise
