| .IP \(bu |
| Portable Network Graphics (PNG) |
| .IP \(bu |
| JPEG Interchange Format (JPEG) |
| .IP \(bu |
| Tagged Image File Format (TIFF) |
| .IP \(bu |
| Portable Document Format (PDF) |
| .IP \(bu |
| PostScript (PS) |

| Encapsulated PostScript (EPS) |
| .IP \(bu |
| Scalable Vector Graphics (SVG) |
| .IP \(bu |
| Windows Printer |
| .PP |
| .B pdftocairo |
| reads the PDF file, |
| .IR PDF-file , |
| and writes to |
| .IR output-file . |
| The image formats (PNG, JPEG, and TIFF) generate one file per page with the page number and file type appended to |
| .IR output-file . |
| When \-singlefile is used with the image formats, the file type is appended to |
| .IR output-file . |
| When the output format is a vector format (PDF, PS, EPS, and SVG), |
| .IR output-file |
| is the full filename. |
| |
| If the |
| .IR PDF-file |
| is \*(lq\-\*(rq , the PDF is read from stdin. |
| If the |
| .IR output-file |
| is \*(lq\-\*(rq , the output file will be written to stdout. Using stdout is not valid with image formats unless \-singlefile is used. |
| If |
| .IR output-file |
| is not used, the output filename will be derived from the |
| .IR PDF-file |
| filename. |
| .PP |
| 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. |
| .PP |
| 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. |
| .PP |
| The \-scale-to options may be used to set a fixed image size. The |
| image resolution will vary with the page size. |
| .PP |
| 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). |

| .SH JPEG OPTIONS |
| 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: |
| .TP |
| .BI quality |
| Selects the JPEG quality value. The value must be an integer between 0 and 100. |
| .TP |
| .BI progressive |
| Select progressive JPEG output. The possible values are "y", "n", |
| indicating progressive (yes) or non-progressive (no), respectively. |
| .SH WINDOWS PRINTER OPTIONS |
| In Windows, you can use the \-print option to print directly to a system printer. Additionally, you can use the \-printopt |
| option to configure the printer. It takes a string of the form "<opt>=<val>[,<opt>=<val>]". Currently the available options are: |
| .TP |
| .BI source |
| Selects the source paper tray to be used (bin). The possible values are "upper", "onlyone", "lower", "middle", "manual", "envelope", |
| "envmanual", "auto", "tractor", "smallfmt", "largefmt", "largecapacity", "formsource", or a numeric value to choose a driver specific source. |
| .TP |
| .BI duplex |
| Sets the duplex mode of the printer. The possible values are "off", "short" or "long", |
| indicating no duplexing, short-edge binding, or long-edge binding, respectively. |
| General option \-duplex is a synonym of "duplex=long". If both options are specified, |
| \-printopt has priority. |
