10 pdftocairo [options] PDF-file [output-file]
11
13 pdftocairo converts Portable Document Format (PDF) files, using the
14 cairo output device of the poppler PDF library, to any of the following
15 output formats:
16 · Portable Network Graphics (PNG)
18 · JPEG Interchange Format (JPEG)
20 · Tagged Image File Format (TIFF)
22 · Portable Document Format (PDF)
24 · PostScript (PS)
26 · Encapsulated PostScript (EPS)
28 · Scalable Vector Graphics (SVG)
30 · Windows Printer
32 pdftocairo reads the PDF file, PDF-file, and writes to output-file.
34 The image formats (PNG, JPEG, and TIFF) generate one file per page with
35 the page number and file type appended to output-file. When -single‐
36 file is used with the image formats, the file type is appended to out‐
37 put-file. When the output format is a vector format (PDF, PS, EPS, and
38 SVG), output-file is the full filename.
39 If the PDF-file is “-” , the PDF is read from stdin. If the output-
41 file is “-” , the output file will be written to stdout. Using stdout
42 is not valid with image formats unless -singlefile is used. If output-
43 file is not used, the output filename will be derived from the PDF-file
44 filename.
45 Not all options are valid with all output formats. One (and only one)
47 of the output format options (-png, -jpeg, -tiff, -pdf, -print, -ps,
48 -eps, or -svg) must be used.
49 The resolution options (-r, -rx, -ry) set the resolution of the image
51 output formats. The image dimensions will depend on the PDF page size
52 and the resolution. For the vector outputs, regions of the page that
53 can not be represented natively in the output format (eg translucency
54 in PS) will be rasterized at the resolution specified by the resolution
55 options.
56 The -scale-to options may be used to set a fixed image size. The image
58 resolution will vary with the page size.
59 The cropping options (-x, -y, -W, and -H) use units of pixels with the
61 image formats and PostScript points (1/72 inch) with the vector for‐
62 mats. When cropping is used with vector output the cropped region is
63 centered unless -nocenter is used in which case the cropped region is
64 at the top left (SVG) or bottom left (PDF, PS, EPS).
65
67 -png Generates a PNG file(s)
68 -jpeg Generates a JPEG file(s). See also -jpegopt.
70 -tiff Generates a TIFF file(s)
72 -pdf Generates a PDF file
74 -ps Generate a PS file
76 -eps Generate an EPS file. An EPS file contains a single image, so if
78 you use this option with a multi-page PDF file, you must use -f
79 and -l to specify a single page. The page size options (-orig‐
80 pagesizes, -paper, -paperw, -paperh) can not be used with this
81 option.
82 -svg Generate a SVG (Scalable Vector Graphics) file
84 -print (Windows only) Prints to a system printer. See also -printer and
86 -printeropt.
87 If an output file is not specified, the output will be sent to
88 the printer.
89 The output file '-' can not be used with this option.
90 -printdlg
92 (Windows only) Prints to a system printer. Displays the print
93 dialog to allow the print options to be modified before print‐
94 ing.
95 -f number
97 Specifies the first page to convert.
98 -l number
100 Specifies the last page to convert.
101 -o Generates only the odd numbered pages.
103 -e Generates only the even numbered pages.
105 -singlefile
107 Writes only the first page and does not add digits.
108 -r number
110 Specifies the X and Y resolution, in pixels per inch of image
111 files (or rasterized regions in vector output). The default is
112 150 PPI.
113 -rx number

121 (or rasterized regions in vector output). The default is 150
122 PPI.
123 -scale-to number
125 Scales the long side of each page (width for landscape pages,
126 height for portrait pages) to fit in scale-to pixels. The size
127 of the short side will be determined by the aspect ratio of the
128 page (PNG/JPEG/TIFF only).
129 -scale-to-x number
131 Scales each page horizontally to fit in scale-to-x pixels. If
132 scale-to-y is set to -1, the vertical size will determined by
133 the aspect ratio of the page (PNG/JPEG/TIFF only).
134 -scale-to-y number
136 Scales each page vertically to fit in scale-to-y pixels. If
137 scale-to-x is set to -1, the horizontal size will determined by
138 the aspect ratio of the page (PNG/JPEG/TIFF only).
139 -x number
141 Specifies the x-coordinate of the crop area top left corner in
142 pixels (image output) or points (vector output)
143 -y number
145 Specifies the y-coordinate of the crop area top left corner in
146 pixels (image output) or points (vector output)
147 -W number
149 Specifies the width of crop area in pixels (image output) or
150 points (vector output) (default is 0)
151 -H number
153 Specifies the height of crop area in pixels (image output) or
154 points (vector output) (default is 0)
155 -sz number
157 Specifies the size of crop square in pixels (image output) or
158 points (vector output) (sets -W and -H)
159 -cropbox
161 Uses the crop box rather than media box when generating the
162 files (PNG/JPEG/TIFF only)
163 -mono Generate a monochrome file (PNG and TIFF only).
165 -gray Generate a grayscale file (PNG, JPEG, and TIFF only).
167 -antialias
169 Set the cairo antialias option used for text and drawing in
170 image files (or rasterized regions in vector output). The
171 options are:
172 default
174 Use the default antialiasing for the target device. This
175 is the default setting if -antialias is not used.
176 none Antialiasing is disabled.
178 gray Perform single-color antialiasing using shades of gray.
180 subpixel
182 Perform antialiasing by taking advantage of the order of
183 subpixel elements on devices such as LCD.
184 fast Hint that the backend should perform some antialiasing
186 but prefer speed over quality.
187 good The backend should balance quality against performance.
189 best Hint that the backend should render at the highest qual‐
191 ity, sacrificing speed if necessary.
192 -transp
194 Use a transparent page color instead of white (PNG and TIFF
195 only).
196 -icc icc-file
198 Use the specified ICC file as the output profile (PNG only). The
199 profile will be embedded in the PNG file.
200 -jpegopt jpeg-options
202 When used with -jpeg, takes a list of options to control the
203 jpeg compression. See JPEG OPTIONS for the available options.
204 -level2
206 Generate Level 2 PostScript (PS only).
207 -level3
209 Generate Level 3 PostScript (PS only). This enables all Level 2
210 features plus shading patterns and masked images. This is the
211 default setting.
212 -origpagesizes
214 This option is the same as "-paper match".
215 -paper size
217 Set the paper size to one of "letter", "legal", "A4", or "A3"
218 (PS,PDF,SVG only). This can also be set to "match", which will
219 set the paper size of each page to match the size specified in
220 the PDF file. If none the -paper, -paperw, or -paperh options
221 are specified the default is to match the paper size.
222 -paperw size
224 Set the paper width, in points (PS,PDF,SVG only).
225 -paperh size
227 Set the paper height, in points (PS,PDF,SVG only).
228 -nocrop
230 By default, printing output is cropped to the CropBox specified
231 in the PDF file. This option disables cropping (PS,PDF,SVG
232 only).
233 -expand
235 Expand PDF pages smaller than the paper to fill the paper
236 (PS,PDF,SVG only). By default, these pages are not scaled.
237 -noshrink
239 Don't scale PDF pages which are larger than the paper
240 (PS,PDF,SVG only). By default, pages larger than the paper are
241 shrunk to fit.
242 -nocenter
244 By default, PDF pages smaller than the paper (after any scaling)
245 are centered on the paper. This option causes them to be
246 aligned to the lower-left corner of the paper instead
247 (PS,PDF,SVG only).
248 -duplex
250 Adds the %%IncludeFeature: *Duplex DuplexNoTumble DSC comment to
251 the PostScript file (PS only). This tells the print manager to
252 enable duplexing.
253 -printer printer-name
255 (Windows only). When used with -print, specifies the name of the
256 printer to be used, instead of the system default.
257 -printopt printer-options
259 (Windows only). When used with -print, takes a list of options
260 to be used to configure the printer. See WINDOWS PRINTER OPTIONS
261 for the available options.
262 -setupdlg
264 (Windows only). When used with -print, the printer properties
265 dialog is displayed allowing the print settings to be modified
266 before printing. The paper size selected in the print properties
267 dialog will be used except when -origpagesizes is specified.
268 -opw password
270 Specify the owner password for the PDF file. Providing this
271 will bypass all security restrictions.
272 -upw password
274 Specify the user password for the PDF file.
275 -q Don't print any messages or errors.
277 -v Print copyright and version information.
279 -h Print usage information. (-help and --help are equivalent.)
281
283 The poppler tools use the following exit codes:
284 0 No error.
286 1 Error opening a PDF file.
288 2 Error opening an output file.
290 3 Error related to PDF permissions.
292 4 Error related to ICC profile.
294 99 Other error.
296
298 When JPEG output is specified, the -jpegopt option can be used to con‐
299 trol the JPEG compression parameters. It takes a string of the form
300 "<opt>=<val>[,<opt>=<val>]". Currently the available options are:
301 quality
303 Selects the JPEG quality value. The value must be an integer
304 between 0 and 100.
305 progressive
307 Select progressive JPEG output. The possible values are "y",
308 "n", indicating progressive (yes) or non-progressive (no),
309 respectively.
310 optimize
312 Sets whether to compute optimal Huffman coding tables for the
313 JPEG output, which will create smaller files but make an extra
314 pass over the data. The value must be "y" or "n", with "y" per‐
315 forming optimization, otherwise the default Huffman tables are
316 used.
317
319 In Windows, you can use the -print option to print directly to a system
320 printer. Additionally, you can use the -printopt option to configure
321 the printer. It takes a string of the form "<opt>=<val>[,<opt>=<val>]".
322 Currently the available options are:
323 source Selects the source paper tray to be used (bin). The possible
325 values are "upper", "onlyone", "lower", "middle", "manual",
326 "envelope", "envmanual", "auto", "tractor", "smallfmt",
327 "largefmt", "largecapacity", "formsource", or a numeric value to
328 choose a driver specific source.
329 duplex Sets the duplex mode of the printer. The possible values are
331 "off", "short" or "long", indicating no duplexing, short-edge
332 binding, or long-edge binding, respectively. General option
333 -duplex is a synonym of "duplex=long". If both options are spec‐
334 ified, -printopt has priority.
