I need help with some small adjustments with a PDF invoice created from php and zencart.
You NEED to now everything about pdf rectangle data, for instance lines like this should be easy for you:
$ pdf- filledRectangle( PDFOC _ LEFT _ MARGIN+245,$ pos,2,30 )
$ pdf- setColor( 0.9,0.9,0.9 )
$ pdf- addText( $reset _ x,$ pos,6,$ wrapped _ str )
