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.
-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
-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
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.
-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.
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 be-
tween 0 and 100.
progressive
Select progressive JPEG output. The possible values are "y",
"n", indicating progressive (yes) or non-progressive (no), re-
spectively.
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.
