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  assum-ing assuming
                ing 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  dis-crete discrete
                crete 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.



FILES
       If no -n options are given, output is written to the standard output.


UNITS
       The units of the W, H, R, and D values above are in inches by default.  Any floating point value  may
       be  used.   Units  of inches, centimetres, millimetres or points (72 per inch) can be used instead by
       appending one of the strings `in', `cm', `mm', or `pt' to the argument (e.g. -d2,4cm).


CUT AND PASTE
       The -d and -p options allow efix to cut out images from received faxes for use in other faxes or doc-uments. documents.
       uments.   The  -d  option specifies the top left portion of the desired image and the -p option gives
       the size of the cut image.  For example, the command
                   efix -d-5,-8 -p2,1 sample.001 >sig.001
       would cut out part of the input with its top left corner 5 inches from the left  edge  and  8  inches
       from top of the input image.  The output image would be 2 inches wide and 1 inch high.

       The -O option allows efix to superimpose two or more images.  The overlay image must be in fax format
       and cannot be scaled, truncated or shifted. However, multiple efix commands may be used to  transform
       images before combining them.  For example, the commands
                   efix -d4,8 signature >sig.fax
                   efix -O sig.fax letterhead >letterhead.fax
                   efix -O letterhead.fax letter.002 >letter.002.new
       will  shift the image in the file signature down 8 inches and right 4 inches and combine (overlay) it
       with the images in the files letterhead and letter.002.
