<h1>Line breaks and colors</h1>
Let's continue with an example which prints justified paragraphs. It also illustrates the use
of colors.

The <a href='../doc/getstringwidth.htm'>GetStringWidth()</a> method allows to determine the length of a string in the current font,
which is used here to calculate the position and the width of the frame surrounding the title.
Then colors are set (via <a href='../doc/setdrawcolor.htm'>SetDrawColor()</a>, <a href='../doc/setfillcolor.htm'>SetFillColor()</a> and <a href='../doc/settextcolor.htm'>SetTextColor()</a>) and the
thickness of the line is set to 1 mm (against 0.2 by default) with <a href='../doc/setlinewidth.htm'>SetLineWidth()</a>. Finally,
we output the cell (the last parameter to 1 indicates that the background must be filled).
<BR>
<BR>
The method used to print the paragraphs is <a href='../doc/multicell.htm'>MultiCell()</a>. Each time a line reaches the
right extremity of the cell or a carriage-return character is met, a line break is issued
and a new cell automatically created under the current one. Text is justified by default.
<BR>
<BR>
Two document properties are defined: title (<a href='../doc/settitle.htm'>SetTitle()</a>) and author (<a href='../doc/setauthor.htm'>SetAuthor()</a>).
Properties can be viewed by two means. First is open the document directly with Acrobat Reader,
go to the File menu, Document info, General. Second, also available from the plug-in, is click
on the triangle just above the right scrollbar and choose Document info.
