Usage: {$_SERVER["argv"][0]} [options] html_file
|
|
|
|
html_file can be a filename, a url if fopen_wrappers are enabled, or the '-' character to read from standard input.
|
|
|
|
Options:
|
|
-h Show this message
|
|
-l List available paper sizes
|
|
-p size Paper size; something like 'letter', 'A4', 'legal', etc.
|
|
The default is '$default_paper_size'
|
|
-o orientation Either 'portrait' or 'landscape'. Default is 'portrait'
|
|
-b path Set the 'document root' of the html_file.
|
|
Relative urls (for stylesheets) are resolved using this directory.
|
|
Default is the directory of html_file.
|
|
-f file The output filename. Default is the input [html_file].pdf
|
|
-v Verbose: display html parsing warnings and file not found errors.
|
|
-d Very verbose: display oodles of debugging output: every frame
|
|
in the tree printed to stdout.
|
|
-t Comma separated list of debugging types (page-break,reflow,split)
