TVLOD
Type: Verb
Use:  TVLOD loads a cataloged map into one or more television image
      memories.  The first image satisfying all the selection criteria
      given below will be loaded.
Adverbs:
  INNAME......Image name(name).       Standard defaults.
  INCLASS.....Image name(class).      Standard defaults.
  INSEQ.......Image name(seq. #).     0 => highest.
  INDISK......Disk drive # of image.  0 => any.
  TBLC........The Bottom Left-hand pixel of the subarray of
              the map to be displayed. The value (0,0,...)
              means take the entire first plane of the image.
  TTRC........The Top Right-hand pixel of the subarray of
              the map to be displayed.  The value (0,0) means
              take the entire plane of the image.
  TXINC.......Load every TXINC'th column beginning at TBLC.
              TXINC = -1 => interpolate columns to fill as much
              of the screen as possible.  TXINC = -2 =>
              interpolate one column between image columns (if
              possible), -3 => 2 interpolated columns, etc.
  TYINC.......Load every TYINC'th row beginning at TBLC.
              TYINC = -1 => interpolate rows to fill as much of
              the screen as possible.  TYINC = -2 =>
              interpolate one row between image rows (if
              possible), -3 => 2 interpolated rows, etc.
  TVCHAN......Image channel to load.  0  =>  channel 1.
  TVCORN......TV pixel location (X,Y) of the bottom left-corner
              of the image.  0 => center on TV
  PIXRANGE....Min,Max intensity to display. 0 => entire range.
  FUNCTYPE....Image intensity transfer function
              'LN' => linear;        'NE' => negative lin.
              'LG' => log;           'NG' => negative log;
              'L2' => extreme log;   'N2' => negative extra log;
              'SQ' => square root,;  'NQ' => negative square root;
              others => linear.
