"""The ``weasyprint`` command takes two arguments: its input and output.
|
||
The input is a filename or URL to an HTML document, or ``-`` to read
|
||
HTML from stdin. The output is a filename, or ``-`` to write to stdout.
|
||
|
||
More options are available:
|
||
|
||
``-e`` or ``--encoding``
|
||
Force the input character encoding (eg. ``-e utf8``).
|
||
|
||
``-f`` or ``--format``
|
||
Choose the output file format among PDF and PNG (eg. ``-f png``).
|
||
Required if the output is not a ``.pdf`` or ``.png`` filename.
|
||
|
||
``-s`` or ``--stylesheet``
|
||
Add a user CSS stylesheet to the document. (eg. ``-s print.css``).
|
||
Multiple stylesheets are allowed.
|
||
|
||
``-r`` or ``--resolution``
|
||
For PNG output only. Set the resolution in PNG pixel per CSS inch.
|
||
Defaults to 96, which means that PNG pixels match CSS pixels.
|
||
|
||
``--base-url``
|
||
Set the base for relative URLs in the HTML input. Defaults to the input’s
|
||
own URL or the current directory for stdin.
|
||
|
||
``-m`` or ``--media-type``
|
||
Set the media type to use for ``@media``. Defaults to ``print``.
|
||
|
||
``--version``
|
||
Show the version number.
|
||
|
||
``-h`` or ``--help``
|
||
Show the command-line usage.
