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). If PDF-file is '-', 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.
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.
-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.
