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 spec-
              ifying how to decode the CCITT data. These parameters are trans-
              lated  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  sig-
                     nificant 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  vari-
              ous  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 sepa-
              rate 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  scal-
                     ing 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 fol-
                     lowing 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.

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.
