Portable Document Format (PDF) to Portable Pixmap (PPM) converter (version 3.03)
pdftoppm [options] PDF-file PPM-root
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.
-fnumber Specifies the first page to convert.
-lnumber 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.
-rnumber Specifies the X and Y resolution, in DPI. The default is 150 DPI.
-rxnumber Specifies the X resolution, in DPI. The default is 150 DPI.
-rynumber Specifies the Y resolution, in DPI. The default is 150 DPI.
-scale-tonumber 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-xnumber 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-ynumber 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.
-xnumber Specifies the x-coordinate of the crop area top left corner
-ynumber Specifies the y-coordinate of the crop area top left corner
-Wnumber Specifies the width of crop area in pixels (default is 0)
-Hnumber Specifies the height of crop area in pixels (default is 0)
-sznumber 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.
-jpegoptjpeg-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.
-tiffcompressionnone | packbits | jpeg | lzw | deflate Specifies the TIFF compression type. This defaults to "none".
-freetypeyes | no Enable or disable FreeType (a TrueType / Type 1 font rasterizer). This defaults to "yes".
-thinlinemodenone | 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.
-aayes | no Enable or disable font anti-aliasing. This defaults to "yes".
-aaVectoryes | no Enable or disable vector anti-aliasing. This defaults to "yes".
-opwpassword Specify the owner password for the PDF file. Providing this will bypass all security restrictions.
-upwpassword Specify the user password for the PDF file.
-q Don't print any messages or errors.
-sepchar 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.)
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.
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.
