|

| 96 | The <a href='../doc/getstringwidth.htm'>GetStringWidth()</a> method allows to determine the length of a string in the current font,
|
|---|
| 97 | which is used here to calculate the position and the width of the frame surrounding the title.
|
|---|
| 98 | 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
|
|---|
| 99 | thickness of the line is set to 1 mm (instead of 0.2 by default) with <a href='../doc/setlinewidth.htm'>SetLineWidth()</a>. Finally,
|
|---|
| 100 | we output the cell (the last parameter <code>true</code> indicates that the background must
|
|---|
| 101 | be filled).
|
|---|
| 102 | <br>
|
|---|
| 103 | <br>
|
|---|
| 104 | The method used to print the paragraphs is <a href='../doc/multicell.htm'>MultiCell()</a>. Each time a line reaches the
|
|---|
| 105 | right extremity of the cell or a carriage return character is met, a line break is issued
|
|---|
| 106 | and a new cell automatically created under the current one. Text is justified by default.
|
|---|
| 107 | <br>
|
|---|
| 108 | <br>
|
|---|
| 109 | Two document properties are defined: the title (<a href='../doc/settitle.htm'>SetTitle()</a>) and the author (<a href='../doc/setauthor.htm'>SetAuthor()</a>).
|
|---|
| 110 | There are several ways to view them in Adobe Reader. The first one is to open the file directly with
|
|---|
| 111 | the reader, go to the File menu and choose the Properties option. The second one, also available from
|
|---|
| 112 | the plug-in, is to right-click and select Document Properties. The third method is to type the Ctrl+D
|
|---|
| 113 | key combination.
