[Bug 1623639] Re: netpbm: "anytopnm" doesn't recognize some file types

[Peter Selinger]

I second the request to fix this bug, no matter how old the software.
Because it is easy to fix and useful. I am attaching a patch.

Title:
  netpbm: "anytopnm" doesn't recognize some file types

Status in netpbm-free package in Ubuntu:
  Confirmed

Bug description:
  /usr/bin/anytopnm uses the output of "file" to recognize the image format of the input file.
  Apparently the output of "file" has changed, and therefore it is no longer correctly recognized by anytopnm. Example:

  $ file /tmp/x.ppm
  /tmp/x.ppm: Netpbm image data, size = 5100 x 6600, rawbits, pixmap

  However, /usr/bin/anytopnm (line 64) looks for the strings *PBM* |
  *PGM* | *PPM* )

  For example:

  $ cat /tmp/x.ppm | anytopnm
  /usr/bin/anytopnm: unknown file type:  Netpbm image data, size = 5100 x 6600, rawbits, pixmap

  Suggested fix: update /usr/bin/anytopnm to recognize the string
  "Netpbm" in addition to PBM, PGM, PPM.
