示例1: WriteLineToContent
/**
* Writes a text line to the document. It takes care of all the attributes.
* <P>
* Before entering the line position must have been established and the
* <CODE>text</CODE> argument must be in text object scope (<CODE>beginText()</CODE>).
* @param line the line to be written
* @param text the <CODE>PdfContentByte</CODE> where the text will be written to
* @param graphics the <CODE>PdfContentByte</CODE> where the graphics will be written to
* @param currentValues the current font and extra spacing values
* @param ratio
