7 verter (version 3.03)
8
10 pdftoppm [options] PDF-file PPM-root
11
13 Pdftoppm converts Portable Document Format (PDF) files to color image
14 files in Portable Pixmap (PPM) format, grayscale image files in Porta‐
15 ble Graymap (PGM) format, or monochrome image files in Portable Bitmap
16 (PBM) format.
17 Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each
19 page, PPM-root-number.ppm, where number is the page number.
20
22 -f number
23 Specifies the first page to convert.
24 -l number
26 Specifies the last page to convert.
27 -o Generates only the odd numbered pages.
29 -e Generates only the even numbered pages.
31 -singlefile
33 Writes only the first page and does not add digits.
34 -r number
36 Specifies the X and Y resolution, in DPI. The default is 150
37 DPI.
38 -rx number
40 Specifies the X resolution, in DPI. The default is 150 DPI.
41 -ry number
43 Specifies the Y resolution, in DPI. The default is 150 DPI.
44 -scale-to number
46 Scales the long side of each page (width for landscape pages,
47 height for portrait pages) to fit in scale-to pixels. The size
48 of the short side will be determined by the aspect ratio of the
49 page.
50 -scale-to-x number
52 Scales each page horizontally to fit in scale-to-x pixels. If
53 scale-to-y is set to -1, the vertical size will determined by
54 the aspect ratio of the page.
55 -scale-to-y number
57 Scales each page vertically to fit in scale-to-y pixels. If
58 scale-to-x is set to -1, the horizontal size will determined by
59 the aspect ratio of the page.
60 -x number
62 Specifies the x-coordinate of the crop area top left corner
63 -y number
65 Specifies the y-coordinate of the crop area top left corner
66 -W number
68 Specifies the width of crop area in pixels (default is 0)
69 -H number
71 Specifies the height of crop area in pixels (default is 0)
72 -sz number
74 Specifies the size of crop square in pixels (sets W and H)
75 -cropbox
77 Uses the crop box rather than media box when generating the
78 files
79 -mono Generate a monochrome PBM file (instead of a color PPM file).
81 -gray Generate a grayscale PGM file (instead of a color PPM file).
83 -png Generates a PNG file instead a PPM file.
85 -jpeg Generates a JPEG file instead a PPM file.
87 -jpegopt jpeg-options
89 When used with -jpeg, takes a list of options to control the
90 jpeg compression. See JPEG OPTIONS for the available options.
91 -tiff Generates a TIFF file instead a PPM file.
93 -tiffcompression none | packbits | jpeg | lzw | deflate
95 Specifies the TIFF compression type. This defaults to "none".
96 -freetype yes | no
98 Enable or disable FreeType (a TrueType / Type 1 font raster‐
99 izer). This defaults to "yes".
100 -thinlinemode none | solid | shape
102 Specifies the thin line mode. This defaults to "none".
103 "solid":
105 adjust lines with a width less than one pixel to pixel boundary
106 and paint it with a width of one pixel.
107 "shape":
109 adjust lines with a width less than one pixel to pixel boundary
110 and paint it with a width of one pixel but with a shape in pro‐
111 portion to its width.
112 -aa yes | no
114 Enable or disable font anti-aliasing. This defaults to "yes".
115 -aaVector yes | no
117 Enable or disable vector anti-aliasing. This defaults to "yes".
118 -opw password
120 Specify the owner password for the PDF file. Providing this
121 will bypass all security restrictions.
122 -upw password
124 Specify the user password for the PDF file.
125 -q Don't print any messages or errors.
127 -v Print copyright and version information.
129 -h Print usage information. (-help and --help are equivalent.)
131
133 The Xpdf tools use the following exit codes:
134 0 No error.
136 1 Error opening a PDF file.
138 2 Error opening an output file.
140 3 Error related to PDF permissions.
142 99 Other error.
144
146 When JPEG output is specified, the -jpegopt option can be used to con‐
147 trol the JPEG compression parameters. It takes a string of the form
148 "<opt>=<val>[,<opt>=<val>]". Currently the available options are:
149 quality
151 Selects the JPEG quality value. The value must be an integer
152 between 0 and 100.
153 progressive
155 Select progressive JPEG output. The possible values are "y",
156 "n", indicating progressive (yes) or non-progressive (no),
157 respectively.
158 optimize
160 Sets whether to compute optimal Huffman coding tables for the
161 JPEG output, which will create smaller files but make an extra
162 pass over the data. The value must be "y" or "n", with "y" per‐
163 forming optimization, otherwise the default Huffman tables are
164 used.
