uses it as a texture:
osg::Image* klnFace = osgDB::readImageFile("image2.jpg");
KLN89FaceTexture->setImage(klnFace);
How can I use an existing memory image of a jpeg (i.e., not have to
access the hardrive) to accomplish the same task?
i.e., something like:
osg::Image* klnFace = osgDB::readImageMemory(buffer);
KLN89FaceTexture->setImage(klnFace);
