Add-On Write HTML
Informations
Author: AramisLicense: FPDF
Description
This is an enhancement of the WriteHTML() method from tutorial 6. Two tags have been added: P and HR. P with the ALIGN attribute equal to center allows to center a line. HR adds a horizontal rule, either through the whole page or with a width given by the WIDTH attribute.Source
