Description
Draws an arc with the curve origin (0 degrees) starting

arcs
<?php
// create new document
$pdf = pdf_new();
pdf_open_file($pdf);
pdf_begin_page($pdf, 500, 700);
// draw an arc from 90 to 180 degrees
pdf_arc($pdf, 200, 350, 50, 90, 180);
pdf_stroke($pdf);
$font = pdf_findfont($pdf, "Courier", "host", 0);
pdf_setfont($pdf, $font, 20);
