NAME

pdftoppm - Portable Document Format (PDF) to Portable Pixmap (PPM)
converter (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
Portable 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. If
PDF-file is '-', it reads the PDF file from stdin.

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.

-scale-dimension-before-rotation
Swaps horizontal and vertical size for a rotated (landscape)
pdf before scaling instead of after.

-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

-hide-annotations
Do not show annotations

-mono Generate a monochrome PBM file (instead of a color PPM file).

-gray Generate a grayscale PGM file (instead of a color PPM file).

-displayprofile displayprofilefile
If poppler is compiled with colour management support, this
option sets the display profile to the ICC profile stored in
displayprofilefile.

-defaultgrayprofile defaultgrayprofilefile
If poppler is compiled with colour management support, this
option sets the DefaultGray color space to the ICC profile
stored in defaultgrayprofilefile.

-defaultrgbprofile defaultrgbprofilefile
If poppler is compiled with colour management support, this
option sets the DefaultRGB color space to the ICC profile
stored in defaultrgbprofilefile.

-defaultcmykprofile defaultcmykprofilefile
If poppler is compiled with colour management support, this
option sets the DefaultCMYK color space to the ICC profile
stored in defaultcmykprofilefile.

-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
rasterizer). 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 proportion 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.

-progress
Print progress info as each page is generated. Three space-
separated fields are printed to STDERR: the number of the
current page, the number of the last page that will be
generated, and the path to the file written to.

-sep char
Specify single character separator between name and page
number, default - .

-forcenum
Force page number even if there is only one page.

-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
control 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
between 0 and 100.

progressive
Select progressive JPEG output. The possible values are "y",
"n", indicating progressive (yes) or non-progressive (no),
respectively.

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"
performing optimization, otherwise the default Huffman tables
are used.
