[Seaside] Web content to PDF converter

[Brodbeck Andreas]

Hi Bob

Usually I generate HTML to a file with seaside techniques and then convert it with the open source command line tool "wkhtmltopdf". To generate HTML I use something like this:

**************************
	component := ...

	builder := WAHtmlCanvas builder
		codec: (GRCodec forEncoding: 'utf-8');
		fullDocument: true;
		resourceUrl: 'file:///path/to/local/webroot/files';
		rootBlock: [:root |
			root title: 'blabla'.
			root beHtml5.
			root stylesheet resourceUrl: 'css/style.css'.
			component updateRoot: root];
		yourself.

	xhtmlString := builder render: component.

	GRPlatform current write: xhtmlString toFile: 'blabla.html' inFolder: 'xyz'.
**************************

Cheers, Andreas
