Issue in ImageMagick 6.8.9-0 Q16 x86_64

[yugalgupta]

Hi
I am using ImageMagick 6.8.9-0 Q16 x86_64 on linux box

I ran conversion command -alpha transparent -clip -alpha opaque

The resultant image has no transparency.

However, If I ran the same command on ImageMagick 6.8.7-9 Q16 x64

The resultant image has transparency and gives expected result.

The issue with the difference in version? I am not able to find the solution for past 2 days.
Please help and suggest and its very urgent. Thanks in advance.

Can you upgrade to 6.8.9-4 and try again? If that doesn't work please post a link to your image and the exact command line arguments you are using. And please don't double post. I have removed your topic from the Developers board.

"-alpha transparent" and "-alpha opaque" seem to work fine for me, in IM 6.8.9-0.

Please provide your complete command and a sample file.

The command being run is below and an example image is attached. Eg,

convert jpgpath.jpg -alpha transparent -clip -alpha opaque jpgpath.png

Your command on your image, with IM 6.8.9-0 on Windows 8.1 and in-built RSVG, works fine for me. The background becomes transparent.

When using with Inkscape to rasterise SVG, everything apart from the lid become transparent. This is weird.

There have been recent changes in clipping paths, so the image needs testing with the current IM.
