    <div>Hi,<br>
      <br>
      Your internal format needs to be 16bit per channel to I think, so
      GL_UNSIGNED_INT_8_8_8_8_REV might be inappropriate. <br>
      GL_R16UI might do, but I thing you need to use GL_RGBA_INTEGER_EXT
      as source. Alternatively you can use GL_LUMINANCE with
      GL_LUMINACE16F.<br>
      <br>
      What exactly are you doing with the image? <br>
      <br>
      Cheers<br>
      Sebastian<br>

                    <div>Hello,<br>
                      <br>
                    </div>
                    I have a 16bit per channel, 4 channel, image. The
                    format is short (uint16_t). Note that this image is
                    scaled to the full 16bit depth [0, 65536]<br>
                    <br>
                    <br>
                  </div>
                  I have this code that works well for a 8bit, 4 channel
                  image:<br>
                  <br>
                  osg::ref_ptr<osg::Image> image = new
                  osg::Image(); <br>
                   image->setImage(ImageSize, ImageSize,1,<br>
                  GL_RGBA8,<br>
                  GL_RGBA,<br>
                  GL_UNSIGNED_INT_8_8_8_8_REV, <br>
                </div>
                MyDataPtr,<br>
                osg::Image::NO_DELETE);<br>
                <br>
                <br>
                <br>
              </div>
              Now I want to por this to 16bit depth.<br>
            </div>
            How is this done?<br>
            <br>
          </div>
          I tried<br>
          <br>
           image->setImage(ImageSize, ImageSize,1,<br>
          GL_RGBA16UI,<br>
          GL_RGBA,<br>
          GL_UNSIGNED_INT_8_8_8_8_REV, <br>
          MyDataPtr,<br>
          osg::Image::NO_DELETE);<br>
          <br>
        </div>
        But this yields all black textures. How can I do this without
        converting my 16bit image pixel data?<br>
      </div>
