Jmagick and rotating image.

[bob]

Hello,

I am using Jmagick to manupulate and rotate images. When I rotate an
image, it gets a white color where no image is standing (in the
corners). I already tried with convertImg.setBackgroundColor( new
PixelPacket(100,50,100,200) ); but the whitespaces stay... ...white. I
need to have those areas transparent. I am using
imgInfo.setColorspace( ColorspaceType.TransparentColorspace ); so it
must be possible. can annyone help me with this?

When using imagemagick commandline I get what I need by using -
background none -rotate 10

I hope someone can help me.
thanks,
Erik
