- _g_i_f_2_s_t_i_f_f converts Graphical Interchange Format (GIF) image files into
- Stream TIFF (STIFF) format. In addition to conversion of GIF images,
- _g_i_f_2_s_t_i_f_f can perform image gamma correction.
-
- _g_i_f_2_s_t_i_f_f expects at least one GIF image file to be specified on the
- command line after all option switches. By default, _g_i_f_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.
-
- ----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 _g_i_f_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.
-
- ----GGGG _g_0[,_g_1,_g_2]
- This switch provides gamma correction of the image data. The
- gamma value (_g_0, etc.) is typically a value between 0.0 and
- 3.0. A gamma value less than 1.0 will tend to lighten the image
- while a value greater than 1.0 will tend to darken the image. A
- gamma of 1.0 will leave the image data unchanged. The gamma
- value may be specified for each color channel individually or
- as a group. If _g_0 is the only gamma value specified, this value
- will be applied to all channels. Note that GIF images contain
- three color channels, red, green and blue. The default gamma
- value is 1.0 for all channels.
-
- ----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. _g_i_f_2_s_t_i_f_f conforms to the 89a GIF specification.

- 2. All GIF extension blocks are read but ignored.
-
- 3. The Logical Screen Descriptor dimensions are read but ignored.
- Similarly, the image positioning information in the Image Descriptor
- are also ignored.
-
- 4. The GIF image must contain either a Global Color Table or a Local
- Color Table.
-
- 5. The Pixel Aspect ratio, if specified, is ignored.
-
- 6. If _g_i_f_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.
