pdftocairo converts Portable Document Format (PDF) files, using the cairo output device of the pop- pler PDF library, to any of the following output formats:

o Portable Network Graphics (PNG)

o JPEG Interchange Format (JPEG)

o Tagged Image File Format (TIFF)

o Portable Document Format (PDF)

o PostScript (PS)

o Encapsulated PostScript (EPS)

o Scalable Vector Graphics (SVG)

o Windows Printer

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. When -singlefile is used with the image formats, the file type is appended to output-file. When the output format is a vector format (PDF, PS, EPS, and SVG), 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, -print, -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).
