Lv, It sounds like you will need a better image manipulation program. Here are some you can get for free: http://www.gimp.org/ http://www.getpaint.net/
In these programs they should have an option to set the background as transparent, here are some tutorial links: http://graphicdesign.stackexchange.com/questions/6449/add-transparency-to-an-existing-png http://forums.getpaint.net/index.php?/topic/12196-making-backgrounds-of-images-transparent/ After the PNG file has the correct transparency set, it should work fine in OSG. -Nathan On Thu, Mar 14, 2013 at 8:41 AM, Lv Qing <[email protected]> wrote: > Hi, > > I use powerpoint to erase the background > > Thank you! > > Cheers, > Lv > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=53107#53107 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >
