[FIXED] How to get image blob from ImageMagick convert command in php

Issue

It is possible to get a binary blob by using ImageMagick convert via PHP's shell_exec(). It's very difficult to convert such a command to PHP Imagick class. Is there any alternative way to implement this feature?

I am using Imagick like this.

$im = new Imagick('some image');
$im->trimImage(20000);
header ("Content-Type: image/{$im->getImageFormat()}");
echo $im->getImageBlob(); // need output in from of blob

I want do get output result similar to this.

convert imageName.png -alpha set -   white -border 1 -fill none -fuzz 3% -draw "color 0,0 floodfill" -shave 1x1 removed_edges.png

If ImageMagick command returns a binary blob instead of writing to a file, my problems will be solved.

Solution

Appended jpg:- after command instead of image name & it's working.

$command = "convert imageName.png -alpha set - white -border 1 -fill none -fuzz 3% -draw "color 0,0 floodfill" -shave 1x1 jpg:-"; header ("Content-Type: image/jpg"); echo shell_exec($command);
