       "The output image is written in the specified format (ie. that corresponds "

       "The choice of the output channels can be done with the extended filename, "
       "but less easy to handle. To do this, a 'channels' parameter allows you to select "
       "the desired bands at the output. There are 3 modes, the available choices are: \n"
-        " * grayscale :  to display mono image as standard color image. \n"
-        " * rgb : select 3 bands in the input image (multi-bands). \n"
