這是簡單的最適合的實例
🎜 >程式碼如下：

$im = $img->suolue(100);
$img->im = $m;
$img->suolue(300);
$img->merge($m,array('left'=>0,'top'=>0,'touming'=>60));
$img->merge($im,array('right'=>0,'top'=>0,'touming'=>60));
$img->merge($im,array('left'=>0,'bottom'=>0,'touming'=>60));
$img->merge($im,array('right'=>0,'bottom'=>0,'touming'=>60));
$img->write("春天來了",array('left'=>0,'top'=>0,'size'=>30,'color'=>$img ->randcolor(0,180 ),'角度'=>-45,'字體'=>'simfang.ttf','圖明'=>80));
$img->write("春天來了",array('left'=>0,'bottom'=>0,'size'=>30,'color'=>$img ->randcolor(0,180 ),'角度'=>45,'字體'=>'simfang.ttf','圖明'=>80));
$img->write("春天來了",array('right'=>0,'bottom'=>0,'size'=>30,'color'=>$img ->randcolor(0,180 ),'角度'=>-45,'字體'=>'simfang.ttf','圖明'=>80));
$img->write("春天來了",array('right'=>0,'top'=>0,'size'=>30,'color'=>$img ->randcolor(0,180 ),'角度'=>45,'字體'=>'simfang.ttf','圖明'=>80));
$img->display("gif");
