Perfect! When will the 6.8.9-6 leave Beta status? :-)

Sorry I have to bring up this thread again. But the clipping path ist still handled incorrectly on some images when creating a PNG with transparency.

Here is an example image:

https://cloud.netgroup.de/public.php?se ... 7769e4b007

This is the command I used:

convert 02053044.jpg -alpha transparent -clip -alpha opaque -strip 02053044.png

And this is the resulting image:

https://cloud.netgroup.de/public.php?se ... 3a87c925e8

I used the latest release for Windows (6.8.9-7 Q16).

Hi!

I did a little more testing and under Linux with the same release 6.8.9-7 Q16 the problem does NOT occour on the images mentioned in the last post. But on other images it does occour under Linux as well:

This image has the same problem with convert on Windows and on Linux:

https://cloud.netgroup.de/public.php?se ... 0d6e870c71

Here is the result from Linux

https://cloud.netgroup.de/public.php?se ... 397ced0999

And here from Windows:

https://cloud.netgroup.de/public.php?se ... 29b08a05f6

This is all weired :-(

The problem seems to occour only in the 64bit release. With the 32bit release for Windows both images are converted correctly.

Thanks to user "zaratol" who pointed me to:

I am getting the following output in the latest IM6 beta: https://www.dropbox.com/sh/4087t9nkl1g7 ... cgvNa?dl=0. I have fixed the 64 bit issue as reported in the other topic you linked.

p.s. What is the name of that pan in my folder?

The spoon has a minor error at rightmost edge of the handle. But everything else looks pretty good :-)

PS: The pan is a so called "Multi roaster" from the "ZWILLING® Plus" series (http://www.zwilling.com/en/cookware-ser ... tml?page=2)

I found some more images on which even the 32bit release does not work perfect:

Maybe they can help tracking the issue.

Is it possible that the clippath is incorrect for those images?

Hmmm ... but in Photoshop the path is correct on both images.

Not sure what you mean. Create a transparent PNG with Photoshop?
