The osg::Image settings only related to storage of the data, not filtering done by OpenGL. Could it be that your texelFetch(..) function in your GLSL is doing filtering? -- As a general note of using the mailing list for support, could you avoid replying to digest posts as this breaks the threading done by mail clients so that your reply no longer gets associated with the original thread. I find that modern mail clients are good at automatically managing the volume of traffic from mailing lists so there shouldn't really be a need to use the digest options. Robert. Robert.
