|

| 9 | SYNOPSIS
|
|---|
| 10 | pdftopng [options] PDF-file PNG-root
|
|---|
| 11 |
|
|---|
| 12 | DESCRIPTION
|
|---|
| 13 | Pdftopng converts Portable Document Format (PDF) files to color,
|
|---|
| 14 | grayscale, or monochrome image files in Portable Network Graphics (PNG)
|
|---|
| 15 | format.
|
|---|
| 16 |
|
|---|
| 17 | Pdftopng reads the PDF file, PDF-file, and writes one PNG file for each
|
|---|
| 18 | page, PNG-root-nnnnnn.png, where nnnnnn is the page number. If PNG-
|
|---|
| 19 | root is '-', the image is sent to stdout (this is probably only useful
|
|---|
| 20 | when converting a single page).
|
|---|
| 21 |
|
|---|
| 22 | CONFIGURATION FILE
|
|---|
| 23 | Pdftopng reads a configuration file at startup. It first tries to find
|
|---|
| 24 | the user's private config file, ~/.xpdfrc. If that doesn't exist, it
|
|---|
| 25 | looks for a system-wide config file, typically /usr/local/etc/xpdfrc
|
|---|
| 26 | (but this location can be changed when pdftopng is built). See the
|
|---|
| 27 | xpdfrc(5) man page for details.
|
|---|
| 28 |
|
|---|
| 29 | OPTIONS

|---|
| 30 | Many of the following options can be set with configuration file com-
|
|---|
| 31 | mands. These are listed in square brackets with the description of the
