我有一个脚本,可以通过干预来保存和缓存图像,并且它正在100%
工作然而,我想弄清楚我如何能为jpg&添加75%的压缩png文件,但我不知道我会在这种情况下应用它。
我不认为PNG文件可以被压缩而不是软件,所以我不确定它是否相同?
此处有一个压缩示例:http://image.intervention.io/api/save

尝试encode()
方法,您可以在其中指定format
和quality
(jpg
)。因此,每次使用缓存时,请尝试执行以下操作:
$cache_image = Image::cache(function ($image) use ($size, $name) {
$image
->make(...)
->... // any other call to image manipulation methods
->encode('jpg', 75);
// ...
return $image;
});
答案 1 :(得分:2)
您需要使用Image类的save()方法,在其中指定图像的质量。方法save()的实际签名为:
save([string $path, [int $quality], [string $format]])
示例如下:
<br>
// open an image file<br>
$img = Image::make('public/foo.jpg');
<br>
<br>
// save file as jpg with medium quality<br>
$img->save('public/bar.jpg', 60); <br><br>
// save the same file as jpg with default quality<br>
$img->save('public/baz.jpg');<br><br>
// save the file in png format with good quality<br>
$img->save('public/bar.png', 75);<br><br>
// save the image jpg format defined by third parameter<br>
$img->save('public/foo', 80, 'jpg');
