[l2h] Re: image conversion problem in latex2html

[Chittaranjan Mandal]

You suggested:

1.Find out which version of  pnmcrop  you have installed on your system:
  $ pnmcrop --version 
pnmcrop: Version: Netpbm 9.5
pnmcrop: Compiled Thu Aug 10 10:46:39 EDT 2000 by user "prospector"
pnmcrop: BSD defined
pnmcrop: RGB_ENV='RGBDEF'
pnmcrop: RGBENV= 'RGBDEF' (env vbl is unset)


2.Go to the directory  /tmp/l2h3073  
  Are the files still present : image001.ps  image002.ps  p3086.pnm  etc.
  If so, take each part of the command that failed, and do it separately:
   /usr/bin/pnmcrop -verbose  < /tmp/l2h3073/p3086.pnm > test.pnm
   /usr/bin/pnmcrop -verbose -bot -black < test.pnm > test2.pnm
   /usr/bin/pnmcrop -verbose  -l -black < test2.pnm > test3.pnm

$ /usr/bin/pnmcrop -verbose  < /tmp/l2h6757/p6926.pnm> test.pnm
usage:  pnmcrop [-white|-black] [-left] [-right] [-top] [-bottom] [pnmfile]

Now without the -verbose flag:
$ /usr/bin/pnmcrop  < /tmp/l2h6757/p6926.pnm> test.pnm
pnmcrop: cropping 2 rows off the top
pnmcrop: cropping 2 rows off the bottom
pnmcrop: cropping 2 cols off the left
pnmcrop: cropping 5 cols off the right

$ /usr/bin/pnmcrop  -bot -black < test.pnm > test2.pnm
pnmcrop: -black - No such file or directory

Now some other tries:
$ /usr/bin/pnmcrop  -bot-black < test.pnm > test2.pnm
usage:  pnmcrop [-white|-black] [-left] [-right] [-top] [-bottom] [pnmfile]
$ /usr/bin/pnmcrop  -black < test.pnm > test2.pnm
pnmcrop: cropping 3 rows off the bottom
pnmcrop: cropping 2 cols off the left
$ /usr/bin/pnmcrop  -black -bottom < test.pnm > test2.pnm
pnmcrop: -bottom - No such file or directory
$ /usr/bin/pnmcrop  -black < test.pnm > test2.pnm
pnmcrop: cropping 3 rows off the bottom
pnmcrop: cropping 2 cols off the left
$ /usr/bin/pnmcrop  -bot < test.pnm > test2.pnm
pnmcrop: cropping 3 rows off the bottom


Clearly my version of pnmcrop does not like the flags with which it get
invoked by latex2html.

  Find out which version of  pnmcrop  you have installed on your system:
   pnmcrop --version 
  should give necessary information.
  
  Go to the directory  /tmp/l2h3073  
  Are the files still present : image001.ps  image002.ps  p3086.pnm  etc.
  If so, take each part of the command that failed, and do it separately:
   /usr/bin/pnmcrop -verbose  < /tmp/l2h3073/p3086.pnm > test.pnm
   /usr/bin/pnmcrop -verbose -bot -black < test.pnm > test2.pnm
   /usr/bin/pnmcrop -verbose  -l -black < test2.pnm > test3.pnm
  
  Which one fails ?
  If the first, then probably all will fail.
  
  I'd guess that you need to upgrade the netpbm utilities.
  
  
  
  That's all I can suggest until you provide more specific
  information after having done some testing.
  
  Hope this helps,
