[magick-users] convert jpg to png

[Stefan Colella]

Hello all,
I am using this command to convert a jpg to png :
convert  ***.jpg  -matte -background none   -rotate 0 **.png
this is working fine on my windows pc but on a linux server we got a  
problem with 1 jpg . With that jpg we always get a corrupted png.
We got version 6.2.9 on the linux server.

Can it be a problem with the version of imagemagick?
Anyone who got the same problem here? Any help would be great.

I tried to attach the image with this mail but i got a message that my 
message was too big and needed to be approved, so i canceled that message.
If it's needed and if it's allowed i can post the jpg and the resulting png.

Thx in advance

Stefan
