Dashed border around composite image (transparent background)

Recently noticed a strange bug
When we place an image on a transparent background
a dashed border appears around it
Here's the code we are using
Code: Select all
<?php
$canvas = new Imagick();
$canvas->newImage(500, 500, new ImagickPixel('transparent'), 'png');
$im = new Imagick('im_src.png');
$canvas->compositeImage($im, Imagick :: COMPOSITE_DEFAULT, 20, 20);
$canvas->writeImage('im_dst.png');
ImageMagick 6.9.1-2 Q16 amd64
IMagick extension 3.1.2
Is it a bug or some behavior changed recently?

Your image shows rotation that is not in your code. Your image is jpg but your code writes a png. Your image is 488x407, not 500x500.

That's a screenshot, this forum does not allow to attach files
Th rotation is in the source file, it does'nt matter since the same issue we have with other images

try upgrading to the latest version 6.9.1.6. I think this bug has been fixed in more current versions (6.9.1.4 or higher I think).
