jpeg2stiff - convert a Joint Photographic Experts Group (JPEG) image file to Stream TIFF (STIFF)

As shipped in IRIX 6.5. First release of IRIX 6.5.

NAME
     jpeg2stiff - convert a Joint Photographic Experts Group (JPEG) image file
     to Stream TIFF (STIFF)

SYNOPSIS
     jpeg2stiff [-O filename] [-L filename]
                [-h] [-D] JPEGImageFilename ...

DESCRIPTION
     jpeg2stiff converts Joint Photographic Experts Group (JPEG) image files
     into Stream TIFF (STIFF) format.

     jpeg2stiff expects at least one JPEG image file to be specified on the
     command line after all option switches. By default, jpeg2stiff assumes
     that its output should be written to the standard output and messages
     should be written to standard error.

     The input image file(s) must be in the JPEG File Interchange Format
     (JFIF).

     -O filename
               Specifies the name of the file to which the STIFF output will
               be sent.  If the -O option is not specified, output will be
               sent to the standard output.

     -L filename
               Specifies the name of the file to which error, warning and
               informational messages are to be written. If the file specified
               already exists, any messages generated by jpeg2stiff will be
               appended to the end of the file.  If the -L option is not
               specified, message output will be sent to standard error.

     -h        Prints a program usage message to the standard error. This
               usage message also lists the currently supported output
               configurations.

     -D        Specifies verbose output for debugging purposes.

NOTES
     1.   Currently, jpeg2stiff accepts JPEG image data only in the JFIF file
          format. The TIFF 6.0 JPEG format is not currently supported.

     2.   jpeg2stiff can decompress baseline and extended sequential JPEG
          compression methods. Progressive, hierarchical and lossless JPEG
          methods are not currently supported.

     3.   jpeg2stiff accepts grayscale and RGB JPEG image colorspaces. A
          grayscale image will produce a W STIFF image (ST_TYPE_W) and an RGB
          image will produce an RGB STIFF image (ST_TYPE_RGB).
     4.   Only input images with eight bits per component are supported at
          this time.

     5.   If jpeg2stiff is given an unrecognized or incomplete command line
          option switch, it will print a warning message to the standard
          error, ignore the option and continue processing.

ACKNOWLEDGEMENTS
     The jpeg2stiff program uses the JPEG software package provided by the
