TV3LOD
Type: Procedure
Use: TV3LOD loads a cataloged RGB map into three television image
memories. The first plane is taken to be red, the second green,
and the third blue. The procedure clears the three TV channels,
loads the first 3 planes (TBLC(3) = 1 then 2 then 3), and then
turns on the three memories in appropriate colors.
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.
Procedure sets TBLC(3).
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......First image channel to load. 0 => channel 1.
TVCHAN+1 and TVCHAN+2 are also used.
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.
