[osg-users] Image to Array

[Robert Osfield]

Hi Andreas,

There isn't an OSG function to convert an osg::Image into array, there
are however, various ways to access the data, and if you wanted to
write your own conversion tool you could.  Have a look at the template
helpers in include/osg/ImageUtils.

Robert.
