NAME

       pdfimages - Portable Document Format (PDF) image extractor (version 3.03)

SYNOPSIS

       pdfimages [options] PDF-file image-root

DESCRIPTION

       Pdfimages  saves  images  from  a  Portable  Document Format (PDF) file as Portable Pixmap
       (PPM), Portable Bitmap (PBM), Portable Network Graphics (PNG), Tagged  Image  File  Format
       (TIFF), JPEG, JPEG2000, or JBIG2 files.

       Pdfimages  reads  the  PDF file PDF-file, scans one or more pages, and writes one file for
       each image, image-root-nnn.xxx, where nnn is the image number and xxx is  the  image  type
       (.ppm, .pbm, .png, .tif, .jpg, jp2, jb2e, or jb2g).

       The  default  output  format is PBM (for monochrome images) or PPM for non-monochrome. The
       -png or -tiff options change to default output to PNG or TIFF respectively. If  both  -png
       and  -tiff are specified, CMYK images will be written as TIFF and all other images will be
       written as PNG. In addition the -j, -jp2, and -jbig2 options will  cause  JPEG,  JPEG2000,
       and JBIG2, respectively, images in the PDF file to be written in their native format.

OPTIONS

       -f number
              Specifies the first page to scan.

       -l number
              Specifies the last page to scan.

       -png   Change the default output format to PNG.

       -tiff  Change the default output format to TIFF.

       -j     Write  images  in JPEG format as JPEG files instead of the default format. The JPEG
              file is identical to the JPEG data stored in the PDF.

       -jp2   Write images in JPEG2000 format as JP2 files instead of the default format. The JP2
              file is identical to the JPEG2000 data stored in the PDF.

       -jbig2 Write  images  in  JBIG2 format as JBIG2 files instead of the default format. JBIG2
              data in PDF is of the embedded type. The embedded type of  JBIG2  has  an  optional
              separate  file  containing  global  data.  The  embedded  data  is written with the
              extension .jb2e and the global data (if available) will  be  written  to  the  same
              image number with the extension .jb2g. The content of both these files is identical
              to the JBIG2 data in the PDF.

       -ccitt Write images in CCITT format as CCITT files instead  of  the  default  format.  The
              CCITT  file  is  identical  to  the CCITT data stored in the PDF. PDF files contain
              additional parameters specifying how to decode the CCITT data. These parameters are
              translated  to  fax2tiff  input options and written to a .params file with the same
              image number. The parameters are:

              -1     1D Group 3 encoding

              -2     2D Group 3 encoding

              -4     Group 4 encoding

              -A     Beginning of line is aligned on a byte boundary

              -P     Beginning of line is not aligned on a byte boundary

              -X n   The image width in pixels

              -W     Encoding uses 1 for black and 0 for white

              -B     Encoding uses 0 for black and 1 for white

              -M     Input data fills from most significant bit to least significant bit.

       -all   Write JPEG, JPEG2000, JBIG2, and CCITT images in their native  format.  CMYK  files
              are  written  as  TIFF  files.  All other images are written as PNG files.  This is
              equivalent to specifying the options -png -tiff -j -jp2 -jbig2 -ccitt.

       -list  Instead of writing the images, list the images along with various  information  for
              each image. Do not specify an image-root with this option.

              The following information is listed for each image:

              page   the page number containing the image

              num    the image number

              type   the image type:

                     image - an opaque image
                     mask - a monochrome mask image
                     smask - a soft-mask image
                     stencil - a monochrome mask image used for painting a color or pattern

              Note:  Tranparency  in  images is represented in PDF using a separate image for the
              image and the mask/smask.  The mask/smask used  as  part  of  a  transparent  image
              always immediately follows the image in the image list.

              width  image width (in pixels)

              height image height (in pixels)

              Note:  the  image  width/height is the size of the embedded image, not the size the
              image will be rendered at.

              color  image color space:

                     gray - Gray
                     rgb - RGB
                     cmyk - CMYK
                     lab - L*a*b
                     icc - ICC Based
                     index - Indexed Color
                     sep - Separation
                     devn - DeviceN

              comp   number of color components

              bpc    bits per component

              enc    encoding:

                     image - raster image (may be Flate or LZW compressed but  does  not  use  an
                     image encoding)
                     jpeg - Joint Photographic Experts Group
                     jp2 - JPEG2000
                     jbig2 - Joint Bi-Level Image Experts Group
                     ccitt - CCITT Group 3 or Group 4 Fax

              interp "yes" if the interpolation is to be performed when scaling up the image

              object ID
                     the image dictionary object ID (number and generation)

              x-ppi  The horizontal resolution of the image (in pixels per inch) when rendered on
                     the pdf page.

              y-ppi  The vertical resolution of the image (in pixels per inch) when  rendered  on
                     the pdf page.

              size   The  size  of the embedded image in the pdf file. The following suffixes are
                     used: 'B' bytes, 'K' kilobytes, 'M' megabytes, and 'G' gigabytes.

              ratio  The compression ratio of the embedded image.

       -opw password
              Specify the owner password for the  PDF  file.   Providing  this  will  bypass  all
              security restrictions.

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

       -p     Include page numbers in output file names.

       -q     Don't print any messages or errors.

       -v     Print copyright and version information.

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

       The Xpdf tools use the following exit codes:

       0      No error.

       1      Error opening a PDF file.

       2      Error opening an output file.
