php使用GD2绘制几何图形示例

<?php

  header("Content-type: image/png");//将图像输出到浏览器

  $img= imagecreate(400, 200);//创建一个400X200的画布

  $bg= imagecolorallocate($img, 0, 0, 255);//设置背景颜色

  $white= imagecolorallocate($img, 255, 255 ,255);//设置填充颜色

  imagefilledellipse($img, 100, 100, 150, 150,$white);//绘制填充圆形

  imagefilledrectangle($img, 200, 50, 300, 150,$white);//绘制填充正方形

  imagepng($img);//以png格式输出图像

  imagedestroy($img);//释放资源
