This remains /tmp/l2hXXXX > directory and image files in it. I've attached the output from this. These lines are from pnmcrop: pnmcrop: You cannot specify both -sides and either -black or -white pnmcrop: You cannot specify both -sides and either -black or -white pnmcrop: Background color is #c0c0c0 pnmcrop: Cropping 1 pixel from the left border pnmcrop: Cropping 2 pixels from the right border pnmcrop: Cropping 2 pixels from the top border pnmcrop: Cropping 2 pixels from the bottom border pnmcrop: Background color is white pnmcrop: The image is entirely background; there is nothing to crop. pstoimg: Error: "/usr/bin/pnmcrop -verbose < /tmp/l2h27263/p27287.pnm | /usr/bin/pnmcrop -verbose -bot -sides -black | /usr/bin/pnmcrop -verbose -l -sides -black > /tmp/l2h27263/p27287.t01" failed: > 2) Do each netpbm command in error message without piping: > > % /usr/bin/pnmcrop -verbose < /tmp/l2hXXXX/p7196.pnm > tmp1.pnm > (XXXX and '7196' may change to different numbers) > % /usr/bin/pnmcrop -verbose -bot -sides -black < tmp1.pnm > tmp2.pnm > % /usr/bin/pnmcrop -verbose -l -sides -black < tmp2.pnm > tmp3.pnm > > Then, you may know which pnmcrop failed, and the reason. Thank you for the suggestion. The error messages come from the first one: $ /usr/bin/pnmcrop -verbose < /tmp/l2h27263/p27287.pnm >tmp1.pnm pnmcrop: Background color is #c0c0c0 pnmcrop: Cropping 1 pixel from the left border pnmcrop: Cropping 2 pixels from the right border pnmcrop: Cropping 2 pixels from the top border pnmcrop: Cropping 2 pixels from the bottom border pnmcrop: Background color is white pnmcrop: The image is entirely background; there is nothing to crop. The second one also gives: $ /usr/bin/pnmcrop -verbose -bot -sides -black < tmp1.pnm > tmp2.pnm pnmcrop: You cannot specify both -sides and either -black or -white The final one gives a different error message: $ /usr/bin/pnmcrop -verbose -l -sides -black < tmp2.pnm > tmp3.pnm pnmcrop: Too many arguments (2). Only need one: the input filespec Is this a ghostscript bug?
