ImageMagick等效於Box-shadow CSS屬性

Question

我想模仿ImageMagick中的圖像陰影CSS屬性。我希望它表現得完全一樣。有沒有功能或等效的映射？

Answer 1

<?php 
    /* Read the image into the object */ 
    $im = new Imagick('a.jpg'); 
    $im->setImageFormat("png"); 

    /* Make the image a little smaller, maintain aspect ratio */ 
    $im->thumbnailImage(200, null); 

    /* Clone the current object */ 
    $shadow = $im->clone(); 

    /* Set image background color to black (this is the color of the shadow) */ 
    $shadow->setImageBackgroundColor(new ImagickPixel('black')); 

    /* Create the shadow */ 
    $shadow->shadowImage(80, 3, 5, 5); 

    /* Imagick::shadowImage only creates the shadow. That is why the original image is composited over it */ 
    $shadow->compositeImage($im, Imagick::COMPOSITE_OVER, 0, 0); 

/* Display the image */ 
header("Content-Type: image/jpeg"); 
echo $shadow; 
?> 

also you can see imagemagick for bash script

我想你要找的是什麼Imagick::shadowImage（CLI的-shadow開關）
