我怎么能够把形象转换到PHP的PNG? 我已经尝试了几种方法,但没有一种工作。 我可以人工操作,因为这些图像是在另一个地点产生的。
http://www.php.net/manual/en/Function.imagecreate fromgif.php"rel=“nofollow” docs function toload a GIF, 然后imagepng< [。 您还应寄送标题<代码>Content-Type:形象/png,以确保由浏览器适当解释。
<?php
$i = imagecreatefromgif("path or URL of file");
header("Content-Type: image/png");
imagepng($i);
?>
如果你想将其保存到档案中,而不是将其送给浏览器,那么,情况恰恰相反:
<?php
$i = imagecreatefromgif("path or URL of file");
imagepng($i, "converted.png");
?>
