Hi GuiYe, I'm afraid I could not easily understand your email, so will have to guess at what you meant. Is it that you want to do an offscreen render of your scene at higher resolution that the frame buffer, and then write this to disk.
If this is the question your are answering then the answer is to use a pbuffer or FBO to create the desired size of image, render to this, then copy the image and write it to disk. The osgscreencapture example has an example of using a pbuffer to do offscreen rendering.
