- _s_g_i_2_f_a_x converts Silicon Graphics format images to bilevel
- TIFF Class F images in preparation for transmission as
- facsimile. _s_g_i_2_f_a_x is not normally invoked directly; it is
- usually run by _s_e_n_d_f_a_x(1) when an SGI image file is
- submitted for transmission.
-
- Images are converted by scaling them to fill the guaranteed
- reproducible area on a default page. Each RGB pixel _p is
- converted to greyscale according to:
- _pr * %r + _pg * %g + _pb * %b
- where %r, %g, and %b default to 30, 59, and 11,
- respectively. Greyscale images are then process with a high
- pass filter and dithered to a bilevel image. The resultant
- image are written as a TIFF Class F document.
-
- By default, the output image is created with 204 dots/inch
- horizontal resolution and 98 lines/inch vertical resolution.
- The image is written as Group 3 1D-encoded data.
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- ----1111 (----2222) Write the image as Group 3 1D- (2D-) encoded data.
-
- ----bbbb %_b
- Set the %_b parameter used to convert color pixel values
- to greyscale pixel values.
-
- ----gggg %_g
- Set the %_g parameter used to convert color pixel values
- to greyscale pixel values.
-
- ----llll Generate an image at 98 lines/inch vertical resolution.
- know as _l_o_w _r_e_s_o_l_u_t_i_o_n.
-
- ----mmmm Generate an image at 196 lines/inch vertical
- resolution.
-
- ----oooo _f_i_l_e
- Write output to _f_i_l_e instead of the default file named
- ssssggggiiii....ffffaaaaxxxx.
-
- ----rrrr %_r
- Set the %_r parameter used to convert color pixel values
- to greyscale pixel values.

- ----ssss _s_i_z_e
- Set the output size according to the named page size.
- Images are normally created with a system-default page
- size (usually letter-size pages, 8.5" by 11", for sites
- in North America). Alternate page sizes are specified
- symbolically using either the name or abbreviation of
- an entry in the _p_a_g_e_s_i_z_e_s(4F) database; e.g. _a_3 (ISO
- A3), _a_4 (ISO A4), _a_5 (ISO A5), _a_6 (ISO A6), _b_4 (ISO
- B4), _n_a-_l_e_t (North American Letter), _u_s-_l_e_g (American
- Legal), _u_s-_l_e_d (American Ledger), _u_s-_e_x_e (American
- Executive), _j_p-_l_e_t (Japanese Letter), and _j_p-_l_e_g
- (Japanese Legal). Comparisons are case-insensitive and
- any match of a substring of the full page-size name is
- sufficient; e.g. ``legal'' would match ``American
- Legal''.
