Bugzilla Bug 66226

When using dvdauthor with imagemagick 6.0.7.1 buttons in the dvd menu get
interpreted as on big white full screen button. 

This patch is not from me, I got it from somebody else who discovered it at a
ML. I found discussion about this at dvdauthor-users:

http://article.gmane.org/gmane.comp.multimedia.dvdauthor.user/2068

The patch is simple and as I understand wouldn't work with any other version of
IM than 6.0.7.

"You can fix this by either not using ImageMagick when you build
dvdauthor, or patching the code. In src/subgen-image.c line 180,
there's a line that reads:
p.t=255-pdata[x*4+3];
Change this to:
p.t=pdata[x*4+3];"

I don't have any knowledge of coding so I don't know how to go with this
further and if this is the proper way to do things (the discussion following
the above link). I can just apply the patch and watch how it develops with IM
and dvdauthor in the futere.

Have a good one

I confirm the bug with stable imagemagick-6 (works with imagemagick-5). I
modified the sourcecode as explained in the forum (removed the 255- in file
subgen-image.c).

It corrected the bug for me.
Could someone add following attached files to portage?

Hi,

the change to dvdauthor is still relevant with stable IM 6.1.0.1.
