首先确保启动php的gd2库；在php.ini中启动extension=php_gd2.dll;
<span><?php </span><span></span>$im<span>=</span><span><em>imagecreatetruecolor</em></span>(<span>400</span>,<span>300</span>);
$red<span>=</span><span><em>imagecolorallocate</em></span>($im,<span>255</span>,<span>0</span>,<span>0</span>);
<span>//imageellipse($im,40,20,20,20,$red);
</span><span>//imageline($im,0,0,400,300,$red);
</span><span>//imagerectangle($im,10,20,300,200,$red);
</span><span>//imagefilledrectangle($im,20,100,360,150,$red);

</span><span>//imagefilledarc($im,200,150,300,220,40,250,$red,IMG_ARC_PIE);
</span><span>//$srcImage=imagecreatefromjpeg("123.jpg");
</span><span>//$srcImageInfo=getimagesize("123.jpg");
</span><span>//
</span><span>//imagecopy($im,$srcImage,10,5,50,60,$srcImageInfo[0],$srcImageInfo[1]);
</span><span>//imagestring($im,22,5,8,'hello World',$red);
</span>$str<span>=</span><span>'hello word,</span><span>天津海港城</span><span>'</span>;
<span>//msyhbd.ttf</span><span>为支持中文的字体，在</span><span>C:WINDOWS/FONTS</span><span>里复制到目录；
</span><span><em>imagettftext</em></span>($im,<span>25</span>,<span>10</span>,<span>15</span>,<span>140</span>,$red,<span>"msyhbd.ttf"</span>,$str);
<span><em>header</em></span>(<span>"content-type:image/png"</span>);
<span><em>imagepng</em></span>($im);
<span><em>imagedestroy</em></span>($im);<img src="http://image.codes51.com/Article/image/20150817/20150817194617_6326.jpg" alt=""><br><p><span><img src="http://image.codes51.com/Article/image/20150817/20150817194617_7107.jpg" alt=""><br></span></p>
