示例 #1 ImagickDraw::arc() example
<?php
function arc($strokeColor, $fillColor, $backgroundColor, $startX, $startY, $endX, $endY, $startAngle, $endAngle) {
//Create a ImagickDraw object to draw into.
$draw = new \ImagickDraw();
$draw->setStrokeWidth(1);
$draw->setStrokeColor($strokeColor);
$draw->setFillColor($fillColor);
$draw->setStrokeWidth(2);
