NAME

       pdftoppm - Portable Document Format (PDF) to Portable Pixmap (PPM) con-
       verter (version 3.03)


SYNOPSIS

       pdftoppm [options] PDF-file PPM-root


DESCRIPTION

       Pdftoppm converts Portable Document Format (PDF) files to  color  image
       files  in Portable Pixmap (PPM) format, grayscale image files in Porta-
       ble Graymap (PGM) format, or monochrome image files in Portable  Bitmap
       (PBM) format.

       Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each
       page, PPM-root-number.ppm, where number is the page number.


OPTIONS

       -f number
              Specifies the first page to convert.

       -l number
              Specifies the last page to convert.

       -o     Generates only the odd numbered pages.

       -e     Generates only the even numbered pages.

       -singlefile
              Writes only the first page and does not add digits.

       -r number
              Specifies the X and Y resolution, in DPI.  The  default  is  150
              DPI.

       -rx number
              Specifies the X resolution, in DPI.  The default is 150 DPI.

       -ry number
              Specifies the Y resolution, in DPI.  The default is 150 DPI.

       -scale-to number
              Scales  the  long  side of each page (width for landscape pages,
              height for portrait pages) to fit in scale-to pixels.  The  size
              of  the short side will be determined by the aspect ratio of the
              page.

       -scale-to-x number
              Scales each page horizontally to fit in  scale-to-x  pixels.  If
              scale-to-y  is  set  to -1, the vertical size will determined by
              the aspect ratio of the page.

       -scale-to-y number
              Scales each page vertically to  fit  in  scale-to-y  pixels.  If
              scale-to-x  is set to -1, the horizontal size will determined by
              the aspect ratio of the page.

       -scale-dimension-before-rotation
              Swaps horizontal and vertical size for a rotated (landscape) pdf
              before scaling instead of after.

       -x number
              Specifies the x-coordinate of the crop area top left corner

       -y number
              Specifies the y-coordinate of the crop area top left corner

       -W number
              Specifies the width of crop area in pixels (default is 0)

       -H number
              Specifies the height of crop area in pixels (default is 0)

       -sz number
              Specifies the size of crop square in pixels (sets W and H)

       -cropbox
              Uses  the  crop  box  rather  than media box when generating the
              files

       -hide-annotations
              Do not show annotations

       -mono  Generate a monochrome PBM file (instead of a color PPM file).

       -gray  Generate a grayscale PGM file (instead of a color PPM file).

       -png   Generates a PNG file instead a PPM file.

       -jpeg  Generates a JPEG file instead a PPM file.

       -jpegopt jpeg-options
              When used with -jpeg, takes a list of  options  to  control  the
              jpeg compression. See JPEG OPTIONS for the available options.

       -tiff  Generates a TIFF file instead a PPM file.

       -tiffcompression none | packbits | jpeg | lzw | deflate
              Specifies the TIFF compression type.  This defaults to "none".

       -freetype yes | no
              Enable  or  disable  FreeType  (a TrueType / Type 1 font raster-
              izer).  This defaults to "yes".

       -thinlinemode none | solid | shape
              Specifies the thin line mode. This defaults to "none".

       "solid":
              adjust lines with a width less than one pixel to pixel  boundary
              and paint it with a width of one pixel.

       "shape":
              adjust  lines with a width less than one pixel to pixel boundary
              and paint it with a width of one pixel but with a shape in  pro-
              portion to its width.

       -aa yes | no
              Enable or disable font anti-aliasing.  This defaults to "yes".

       -aaVector yes | no
              Enable or disable vector anti-aliasing.  This defaults to "yes".

       -opw password

              will bypass all security restrictions.

       -upw password
              Specify the user password for the PDF file.

       -q     Don't print any messages or errors.

       -sep char
              Specify single character separator between name and page number,
              default - .

       -forcenum
              Force page number even if there is only one page.

       -v     Print copyright and version information.

       -h     Print usage information.  (-help and --help are equivalent.)


EXIT CODES

       The Xpdf tools use the following exit codes:

       0      No error.

       1      Error opening a PDF file.

       2      Error opening an output file.

       3      Error related to PDF permissions.

       99     Other error.


JPEG OPTIONS

       When JPEG output is specified, the -jpegopt option can be used to  con-
       trol  the  JPEG  compression parameters.  It takes a string of the form
       "<opt>=<val>[,<opt>=<val>]". Currently the available options are:

       quality
              Selects the JPEG quality value. The value  must  be  an  integer
              between 0 and 100.

       progressive
              Select  progressive  JPEG  output.  The possible values are "y",
              "n",  indicating  progressive  (yes)  or  non-progressive  (no),
              respectively.

       optimize
              Sets  whether  to  compute optimal Huffman coding tables for the
              JPEG output, which will create smaller files but make  an  extra
              pass  over the data. The value must be "y" or "n", with "y" per-
              forming optimization, otherwise the default Huffman  tables  are
              used.
