Inputs


Keyword Parameters


Keywords


        MAG=mag Modify info byte array for an image size change.
          The info will be modified each time this keyword is used,
          even if it is not embedded.
        /NOEMBED Do not embed scaling info in image.
        INFO=info Returned scaling info byte array.
        /LIST List values in info array.
        ERROR=err Error flag: 0=ok.

Outputs


Common Blocks


      map_set2_com

Notes


      Notes: Must use map_set2 to do the map command.
        Works just like map_set but keeps track of info
        needed to restore map projection at a later time
        and packs it into 160 bytes. map_put_scale embeds
        this info in a map image using 160 pixels along the
        bottom left of the image (blue channel for color images).
        Must protect this info from any processing done
        to the image.
