A cube may still be left if the image started with > 3 "real" axes. Adverbs: INNAME......Input name of image(name). Standard defaults. INCLASS.....Input name of image(class). Standard defaults. INSEQ.......Input name of image(seq. #). 0 => highest. INDISK......Disk drive # of image. 0 => any. OUTNAME.....Output name of image(name). Standard defaults. OUTCLASS....Output name of image(class). Standard defaults. OUTSEQ......Output name of image(seq. #). 0 => highest unique OUTDISK.....Disk drive # of Output image. 0 => highest with space. BLC.........The bottom left-hand pixel of the input image which becomes the bottom left corner of the subimage. The value (0,0) means (1,1). TRC.........The top right-hand pixel of the input image which becomes the top right corner of the subimage. The value (0,0) means take the top right hand corner of the image. BDROP.......If > 0, use axis BDROP only If < 0, use all axes >= -BDROP Note BDROP > 1 or BDROP < -1 is required here. It is possible to collapse the 2nd axis to a single pixel. If BDROP = 2, you may want TRANS with TRANCODE '132' on the output to view the image. If BDROP=-2, the result is a single row - run SLICE on that to view the results. DPARM.......Control flags: (1) 0: weighted average; 1: weighted rms; 2: average; 3: rms; 4: sum; 5: maximum; 6: minimum (2) > 0 => ignore blanks unless all contributing planes are blank at the pixel <= 0 => if any plane is blanked at a pixel, blank that pixel on output (3) > 0 use INTEXT for weights INTEXT......Text file giving weights ----------------------------------------------------------------
