sgi2fax - convert a Silicon Graphics image file for facsimile transmission SYNOPSIS
/usr/lib/fax/sgi2fax [ options ] files... DESCRIPTION
sgi2fax converts Silicon Graphics format images to bilevel TIFF Class F images in preparation for transmission as facsimile. sgi2fax is not normally invoked directly; it is usually run by sendfax(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 writ- ten as Group 3 1D-encoded data. OPTIONS
-1 (-2) Write the image as Group 3 1D- (2D-) encoded data. -b %b Set the %b parameter used to convert color pixel values to greyscale pixel values. -g %g Set the %g parameter used to convert color pixel values to greyscale pixel values. -l Generate an image at 98 lines/inch vertical resolution. know as low resolution. -m Generate an image at 196 lines/inch vertical resolution. -o file Write output to file instead of the default file named sgi.fax. -r %r Set the %r parameter used to convert color pixel values to greyscale pixel values. -s size 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 pagesizes(5F) database; e.g. a3 (ISO A3), a4 (ISO A4), a5 (ISO A5), a6 (ISO A6), b4 (ISO B4), na- let (North American Letter), us-leg (American Legal), us-led (American Ledger), us-exe (American Executive), jp-let (Japanese Let- ter), and jp-leg (Japanese Legal). Comparisons are case-insensitive and any match of a substring of the full page-size name is suf- ficient; e.g. ``legal'' would match ``American Legal''. FILES
