'NQ' Negative square root ---------------------------------------------------------------- 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. ----------------------------------------------------------------
