Hi, I try to load a 8bits image and create an osg::Texture2D with it. I search all the day but without sucess.
It seems that the image load by osgDB::readImageFile(...) is transform in a 32 bits image. Is it possible to load it as 8bits image with an associated look up table ? (I didn't find attribut in osg::Image that could correspond to a lut, is there one ?) However if I can load my image as a 8 bits image, I don't know how I can associate the color table to the texture, is there a way to do that ? In fact and to clarify what I mean, here is the code in OpenGL I would like to translate in OpenSceneGraph : glColorTableEXT(GL_TEXTURE_2D, GL_RGBA8, 256, GL_RGBA, GL_UNSIGNED_BYTE, colorTable); glTexImage2D(GL_TEXTURE_2D, 0, GL_COLOR_INDEX8_EXT, width, height, 0, GL_COLOR_INDEX, GL_UNSIGNED_BYTE, texture); I hope I was enough clear. Sorry if I wasn't. Thank you very much for your help.
