       pdfimages [options] PDF-file image-root


       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,, where nnn is the image number and xxx is  the  image  type
       (.ppm,  .pbm, .png, .tif, .jpg, jp2, jb2e, or jb2g).  If PDF-file is ยด-', it reads the PDF
       file from stdin.

       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.


       -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:
