      Embed in current image values needed to restore scaling.


Calling Sequence



Keyword Parameters


        The following are only used to add scaling to an
        existing image not easily regenerated:
        IX=[ix1,ix2] Plot window x device coordinates.
        IY=[iy1,iy2] Plot window y device coordinates.
        X = [x1,x2] Plot window x data coordinates.
        Y = [y1,y2] Plot window y data coordinates.
        TYPE_X=xtyp X axis type: 0=linear, 1=log.
        TYPE_Y=ytyp Y axis type: 0=linear, 1=log.
        LOG=name Logs values to $HOME/put_scale.txt under
          name (anything, but image name is useful).
        TEXT=stxt Returned scaling info as text.
        INFO=bb Returned scaling info as a byte array.


Common Blocks


      Notes: Embeds in dispayed image the following values:
        1234567890 - Used to determine if scaling available (I10).
        ix1, ix2 - Plot window device coordinates in X (2I6).
        iy1, iy2 - Plot window device coordinates in Y (2I6).
        x1, x2 - Plot window data coordinates in X (2G13.6).
        y1, y2 - Plot window data coordinates in Y (2G13.6).
        xtype, ytype - X and Y axis type: 0=linear, 1=log (2I2).
        For type=1 the data range is really the log10 of
        the actual data range for that axis.
        Use set_scale to read these values and set scaling.
        May also read 90 bytes and convert to string:
        Only works if image stored in non-lossy format.
