efix - Online in the Cloud

PROGRAM:

NAME

efix - convert between fax, text, bit-map and gray-scale formats

SYNOPSIS

efix [ options ] file...

OPTIONS

Where options are:

-i f the input image is in format f. Default is to automatically determine the input
type from its contents.

fax fax ("Group3") 1-D coded image

text text. Line feeds separate lines, form feeds cause page breaks and tabs are
expanded assuming tabs every 8 columns.

pbm raw PBM (portable bit map)

tiffg3
TIFF format with Group 3 (fax) compression.

tiffraw
TIFF format with no compression.

-o f write the output in format f. Default is tiffg3.

fax fax ("Group3") 1-D coded image

pbm raw PBM

pgm raw PGM (Portable Gray Map). Gray-scale values are produced by summing pixels in
4x4 pixel blocks. The output file is 1/4 of the size given by -p. The resulting
image has 17 discrete values between 0 and 255.

pcl HP-PCL (e.g. HP LaserJet).

ps encapsulated Postscript (e.g. Apple Laserwriter). The file is compressed using
differential coding vertically and run-length coding horizontally. There is no
provision for positioning the image within the page and so the image will appear
at the lower left corner of the page when printed.

tiffg3
TIFF format with Group 3 (fax) compression.

tiffraw
TIFF format with no compression.

-n pat use the printf(3) pattern path to generate the output file name. Up to three %d
escapes will be replaced by the page number starting with 1 (e.g. -n order.%03d
will create file names order.001, order.002, etc.)

-v lvl print messages of type in string lvl. Each lower-case letter in lvl enables one
type of message:

e - errors
w - warnings
i - information messages
a - program arguments
f - file format details

The default is "ewi".

-f fnt use font file fnt for text. The font file for an WxH font should be a bit map of
an image of H rows and 256*W columns. Each successive WxH cell contains the bit
map for characters with codes from 0 to 255. The default is to use a built-in
8x16 font.

-s XxY scale the input by a factor of X horizontally and Y vertically. Scaling does not
change the size of the output (use -p). If Y is not specified it is assumed to
be the same as X. Any floating point value may be used for X and Y. The default
is 1,1.

-d R,D displace the output right by R and down by D (opposite if negative). See below
for units. Default is 0,0.

-p WxH truncate or pad the output to generate an image of width W and height H. This
does not scale the input. See below for units. The default is the size of the
input image if it can be determined or A4 (215x297mm) if it can't.

-r XxY assume an output device resolution of X by Y dots per inch. If Y is not
specified it is assumed to be the same as X. The default is the input resolution
if it can be determined or the fax resolution of 204.1x195.6 dpi if it can't.

-R XxY assume an input device resolution of X by Y dots per inch. If Y is not specified
it is assumed to be the same as X. The default is the input resolution if it can
be determined or the fax resolution of 204.1x195.6 dpi if it can't.

-l n place n lines per page during text input. Default is 66.

-O f overlay (logical OR) the image from file f into the output. Use "-" for standard
input (-O-). Default is no overlay file.

-M ignore all other options and copy the standard input to the standard output while
applying base64 (MIME) encoding as specified by RFC 1521.
