_j_p_e_g_2_s_t_i_f_f converts Joint Photographic Experts Group (JPEG) image files
into Stream TIFF (STIFF) format.
_j_p_e_g_2_s_t_i_f_f expects at least one JPEG image file to be specified on the
command line after all option switches. By default, _j_p_e_g_2_s_t_i_f_f 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).
----OOOO _f_i_l_e_n_a_m_e
Specifies the name of the file to which the STIFF output will
be sent. If the ----OOOO option is not specified, output will be
sent to the standard output.
----LLLL _f_i_l_e_n_a_m_e
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 _j_p_e_g_2_s_t_i_f_f will be
appended to the end of the file. If the ----LLLL option is not
specified, message output will be sent to standard error.
----hhhh Prints a program usage message to the standard error. This
usage message also lists the currently supported output
configurations.
----DDDD Specifies verbose output for debugging purposes.

1. Currently, _j_p_e_g_2_s_t_i_f_f accepts JPEG image data only in the JFIF file
format. The TIFF 6.0 JPEG format is not currently supported.
2. _j_p_e_g_2_s_t_i_f_f can decompress baseline and extended sequential JPEG
compression methods. Progressive, hierarchical and lossless JPEG
methods are not currently supported.
3. _j_p_e_g_2_s_t_i_f_f accepts grayscale and RGB JPEG image colorspaces. A
grayscale image will produce a W STIFF image (SSSSTTTT____TTTTYYYYPPPPEEEE____WWWW) and an RGB
image will produce an RGB STIFF image (SSSSTTTT____TTTTYYYYPPPPEEEE____RRRRGGGGBBBB).

4. Only input images with eight bits per component are supported at
this time.
5. If _j_p_e_g_2_s_t_i_f_f 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.

The _j_p_e_g_2_s_t_i_f_f program uses the JPEG software package provided by the
Independent JPEG Group. The Independent JPEG Group's software is
available via anonymous ftp from a number of Internet locations.
