NAME

       posterazor - splits an image across multiple pages for assembly into a poster

SYNOPSIS

       posterazor [ inputfile ]

DESCRIPTION

       The PosteRazor splits an image to form a multi-page PDF document. When printed, the sheets
       can be arranged to form a large poster of the original image.

       If no inputfile is specified as a command line argument, the user  will  be  prompted  for
       one.

       Current Features:

              Input image formats
                     All  image formats that FreeImage can read should be usable as input for the
                     PosteRazor: BMP, DDS, Dr. Halo, GIF, ICO, IFF, JBIG, JPEG/JIF,  KOALA,  LBM,
                     Kodak PhotoCD, PCX, PBM, PGM, PNG, PPM, PhotoShop PSD, Sun RAS, TARGA, TIFF,
                     WBMP, XBM, XPM.

              Color types
                     PosteRazor  can  handle  the  following  image  color   types:   Monochrome,
                     Grayscale,  4  Bit  palette, 8 Bit palette, 24 Bit RGB, 48 Bit RGB (only via
                     TIFF and PNG), 32 Bit CMYK (only via TIFF) 32 Bit RGBA images can be loaded,
                     but are transformed to 24 Bit RGB by "merging" them with a white background.

              Dimension units
                     Because  people around the world invented so many different dimension units,
                     PosteRazor supports quite a few: m, mm, cm, inch, ft, pt(72th inch).

              Printer page layout
                     The page size and orientation of  the  printer  where  the  poster  will  be
                     printed  can  be  set  manually  or  selected one from the following list of
                     predefined formats: DIN A4, DIN A3, Legal,  Letter  or  Tabloid.   The  size
                     limit  for  one  page is 5 meters (16.4 feet), which is the maximum that PDF
                     allows.

              Poster size
                     The size of the final poster can be set through one of these three ways:

                     - Absolute image size
                            You want to have a specific size of your poster.

                     - Size in Pages
                            You want to use whole paper sheets and specify how many  of  them  of
                            them you want to use.

                     - Image Size in percent
                            Your input image has a certain size which is defined by the number of
                            pixels and dpi (dots per inch) and your want to scale the image by  a
                            certain factor.

                     The  final  size of the poster is theoretically unlimited. Let's say it this
                     way: it is less limited that the ink of your printer.   It  is  possible  to
                     select  the alignment of the image on the total paper. This is useful if you
                     want to keep the unused paper.

              Image tile overlapping
                     For a bigger tolerance when cutting  spare  paper  borders  and  for  easier
                     pasting,  an overlapping width and height of an image tile over the next can
                     be set.

              PDF output
                     The PDF output is implemented with the maximum  image  quality  and  a  good
                     compression  in  mind.   A source image is embedded once in the PDF document
                     and referenced from every tile page. Image color types remain unchanged.  As
                     compression  method,  the  PDF "FlateDecode filter" (zip) is used. If a JPEG
                     image is used as input it gets directly embedded into the  document  without
                     recompression.   The  PDF version is 1.4, so any compatible reader should be
                     able to read the resulting document.

       Missing Support:

              •  Cut lines/aids;

              •  Support of JPEG-CMYK images;

              •  Support of 16 Bit Grayscale images;

              •  Embedding an ICC profile into the PDF if there is  one  embedded  in  the  input
                 image.
