支持 WebP。
我们在 libwebp 编解码器分发中提供了一个参考实现，
编码器和解码器应用（分别为 cwebp 和 dwebp）
展示 WebP 的可用功能。这些文件可供下载

您的应用或浏览器
在命令行中使用 cwebp 将 PNG 或 JPEG 图片文件转换为 WebP
格式。您可以将 PNG 图片文件转换为具有质量范围的 WebP 图片
（共 80 个）：
cwebp -q 80 image.png -o image.webp
如需了解说明，请参阅 cwebp 文档
及其标准选项和高级选项。
在命令行中使用 dwebp 将 WebP 图片文件转换为 PNG 或 PPM
格式。您可以将 WebP 图片文件（例如 image.webp）转换为 PNG 图片
命令：
dwebp image.webp -o image.png
如需了解说明，请参阅 dwebp 文档
及其命令行选项。
