You first create an image object out of your file with imagecreatefromjpeg(). You then dump that object into different formats (using imagegif() for example):
首先使用imagecreatefromjpeg（）从文件中创建一个图像对象。然后，您将该对象转储为不同的格式（例如，使用imagegif（））：
$imageObject = imagecreatefromjpeg($imageFile);
imagegif($imageObject, $imageFile . '.gif');
imagepng($imageObject, $imageFile . '.png');
imagewbmp($imageObject, $imageFile . '.bmp');

I've set up a new opensource project on Github that allows reading and saving of BMP files (actual BMP files, not wbmp), and other file formats, in PHP. It's nice and easy to use.
我在Github上设置了一个新的开源项目，它允许在PHP中读取和保存BMP文件（实际的BMP文件，而不是wbmp）和其他文件格式。它很好用且易于使用。
