Try this code it comes directly from perfly it is attached to the `xX' on the
keybd....

snapImage(int snapAlpha)
{
    FILE *fp;
    static char str[80];
    static int count = 0;
    pfPipe* cpipe = ViewState->masterChan->getPipe();
    int id = pfGetId(cpipe)*10 + count++;

    sprintf(str, "perfly.%d.%s", id,
            (snapAlpha) ? "rgba" : "rgb");
    pfNotify(PFNFY_INFO, PFNFY_PRINT, "Saving pipe %d image in file %s\n",
            pfGetId(cpipe), str);

    pfuSaveImage(str, 0, 0,
                 ViewState->mouse.winSizeX,
                 ViewState->mouse.winSizeY,
                 (snapAlpha) ? 1 : 0);

    /* create info file to go with image */
    sprintf(str, "perfly.%d.info", id);
    if (fp = fopen(str,"w"))
    {
        float h, v;
        fprintf(fp, "Viewing parameters for snap %d of perfly\n\n", id);
        fprintf(fp, "XYZ: %f %f %f\n",
                ViewState->viewCoord.xyz[0],
                ViewState->viewCoord.xyz[1],
                ViewState->viewCoord.xyz[2]);
        fprintf(fp, "HPR: %f %f %f\n",
                ViewState->viewCoord.hpr[0],
                ViewState->viewCoord.hpr[1],
                ViewState->viewCoord.hpr[2]);
        fprintf(fp, "NEAR/FAR: %f %f \n",
                ViewState->near, ViewState->far);
        ViewState->masterChan->getFOV(&h, &v);
        fprintf(fp, "FOV: horiz=%f vert=%f\n", h, v);
        fclose(fp);
    }

    pfNotify(PFNFY_INFO, PFNFY_PRINT, "Done\n");
}
