NAME¶
pdftocairo - Portable Document Format (PDF) to PNG/JPEG/TIFF/PDF/PS/EPS/SVG
using cairo
SYNOPSIS¶
pdftocairo [options]
PDF-file [
output-file]
DESCRIPTION¶
pdftocairo converts Portable Document Format (PDF) files, using the cairo
output device of the poppler PDF library, to any of the following output
formats:
- •
- Portable Network Graphics (PNG)
- •
- JPEG Interchange Format (JPEG)
- •
- Tagged Image File Format (TIFF)
- •
- Portable Document Format (PDF)
- •
- PostScript (PS)
- •
- Encapsulated PostScript (EPS)
- •
- Scalable Vector Graphics (SVG)
pdftocairo reads the PDF file,
PDF-file, and writes to
output-file. The image formats (PNG, JPEG, and TIFF) generate one file
per page with the page number and file type appended to
output-file
(except when -singlefile is used). When the output format is a vector format
(PDF, PS, EPS, and SVG) or when -singlefile is used,
output-file is the
full filename.
If the
PDF-file is “-” , the PDF is read from stdin. If the
output-file is “-” , the output file will be written to
stdout. Using stdout is not valid with image formats unless -singlefile is
used. If
output-file is not used, the output filename will be derived
from the
PDF-file filename.
Not all options are valid with all output formats. One (and only one) of the
output format options (-png, -jpeg, -tiff, -pdf, -ps, -eps, or -svg) must be
used.
The resolution options (-r, -rx, -ry) set the resolution of the image output
formats. The image dimensions will depend on the PDF page size and the
resolution. For the vector outputs, regions of the page that can not be
represented natively in the output format (eg translucency in PS) will be
rasterized at the resolution specified by the resolution options.
The -scale-to options may be used to set a fixed image size. The image
resolution will vary with the page size.
The cropping options (-x, -y, -W, and -H) use units of pixels with the image
formats and PostScript points (1/72 inch) with the vector formats. When
cropping is used with vector output the cropped region is centered unless
-nocenter is used in which case the cropped region is at the top left (SVG) or
bottom left (PDF, PS, EPS).
OPTIONS¶
- -png
- Generates a PNG file(s)
- -jpeg
- Generates a JPEG file(s)
- -tiff
- Generates a TIFF file(s)
- -pdf
- Generates a PDF file
- -ps
- Generate a PS file
- -eps
- Generate an EPS file. An EPS file contains a single image, so if you use
this option with a multi-page PDF file, you must use -f and -l to specify
a single page. The page size options (-origpagesizes, -paper, -paperw,
-paperh) can not be used with this option.
- -svg
- Generate a SVG (Scalable Vector Graphics) file
- -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 pixels per inch of image files (or
rasterized regions in vector output). The default is 150 PPI.
- -rx number
- Specifies the X resolution, in pixels per inch of image files (or
rasterized regions in vector output). The default is 150 PPI.
- -ry number
- Specifies the Y resolution, in pixels per inch of image files (or
rasterized regions in vector output). The default is 150 PPI.
- -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 (PNG/JPEG/TIFF only).
- -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 (PNG/JPEG/TIFF only).
- -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 (PNG/JPEG/TIFF only).
- -x number
- Specifies the x-coordinate of the crop area top left corner in pixels
(image output) or points (vector output)
- -y number
- Specifies the y-coordinate of the crop area top left corner in pixels
(image output) or points (vector output)
- -W number
- Specifies the width of crop area in pixels (image output) or points
(vector output) (default is 0)
- -H number
- Specifies the height of crop area in pixels (image output) or points
(vector output) (default is 0)
- -sz number
- Specifies the size of crop square in pixels (image output) or points
(vector output) (sets -W and -H)
- -cropbox
- Uses the crop box rather than media box when generating the files
(PNG/JPEG/TIFF only)
- -mono
- Generate a monochrome file (PNG and TIFF only).
- -gray
- Generate a grayscale file (PNG, JPEG, and TIFF only).
- -transp
- Use a transparent page color instead of white (PNG and TIFF only).
- -icc icc-file
- Use the specified ICC file as the output profile (PNG only). The profile
will be embedded in the PNG file.
- -level2
- Generate Level 2 PostScript (PS only).
- -level3
- Generate Level 3 PostScript (PS only). This enables all Level 2 features
plus shading patterns and masked images. This is the default setting.
- -origpagesizes
- This option is the same as "-paper match".
- -paper size
- Set the paper size to one of "letter", "legal",
"A4", or "A3" (PS,PDF,SVG only). This can also be set
to "match", which will set the paper size of each page to match
the size specified in the PDF file. If none the -paper, -paperw, or
-paperh options are specified the default is to match the paper size.
- -paperw size
- Set the paper width, in points (PS,PDF,SVG only).
- -paperh size
- Set the paper height, in points (PS,PDF,SVG only).
- -nocrop
- By default, printing output is cropped to the CropBox specified in the PDF
file. This option disables cropping (PS,PDF,SVG only).
- -expand
- Expand PDF pages smaller than the paper to fill the paper (PS,PDF,SVG
only). By default, these pages are not scaled.
- -noshrink
- Don't scale PDF pages which are larger than the paper (PS,PDF,SVG only).
By default, pages larger than the paper are shrunk to fit.
- -nocenter
- By default, PDF pages smaller than the paper (after any scaling) are
centered on the paper. This option causes them to be aligned to the
lower-left corner of the paper instead (PS,PDF,SVG only).
- -duplex
- Adds the %%IncludeFeature: *Duplex DuplexNoTumble DSC comment to the
PostScript file (PS only). This tells the print manager to enable
duplexing.
- -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 poppler 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.
- 4
