如何使用 Laravel 在干预图像包中设置图像大小和尺寸

Question

I'm using the Intervention Image package for manipulating the uploaded image before saving it to the server. I have successfully set the dimension of the image, and it's working fine, but I want to fix the image size, ie, the image generated should be less than equals to 30KB and should have a resolution of 300 dpi only.

Here is the code, I'm using to resize the uploaded image:

$file = $post->file('profile_image');

$filename = Carbon::now()->timestamp.'_'.$file->getClientOriginalName();

\Image::make($file->getRealPath())->resize(160, 160)->save('uploads/profile/'.$filename);

If my concern is feasible with the Intervention Image package, please give me a solution.

Thanks in advance.

Answer 1

you can try somthing like this

$size = 160;
$img = \Image::make($file->getRealPath())->resize($size, $size)->save('uploads/profile/'.$filename);
while($img->filesize() < "someAmount"){
    $size = (int)$size - 20; // adjust based on your need
    $img = \Image::make($file->getRealPath())->resize($size, $size)->save('uploads/profile/'.$filename);
}

NOTE this is not correct answer but it is idea to solve this problem
