PDFLib question

[andrewthorp]

Ok, I am not new to PHP, but I am not as comfortable with PDFLib, and I am aware that I am probably just doing something stupid, but this has really been bugging me!

 

pdf_moveto($this->pdf, $this->baseX, $this->baseY);
pdf_lineto($this->pdf, $this->baseX+710, $this->baseY);
pdf_stroke($this->pdf);

 

My baseX = 0, and baseY is irrelevant.

 

For some reason, the line that it draws is 727 pixels long, even though 0 + 710 is stated.

 

Why is this happening? Any thoughts?
