Date: Thu, 16 Jan 2003 13:48:31 +0200 From: "Mike Gorchak" added help and options -mono to force monochrome RGB2YUB conversion and -lum <percent> - luminance of image during conversion. Also rewritten code which moves overlay into window. Now it depends on window size. Also fully rewritten -scale option, image now scaling from 50% from center of screen until border of window is reached - it really tests scaler, old -scale test doesn't test downscale.

README by Mike Gorchak <mike@malva.ua>, <lestat@i.com.ua>

    OpenGL in window mode  works well  and  stable, in fullscreen
mode too, but fullscreen mode has not been heavily tested.
    If you have QNX RtP 6.1.0 w/ or w/o Patch A you must download
new Photon3D runtime from http://developers.qnx.com. The versions
of OS before 6.1.0 are not supported.

Problems:
1. While  creating  OpenGL  context  software  renderer  mode  is
   artificially selected (QSSL made acceleration only for  Voodoo
   boards in fullscreen mode, sorry but I don't have  this board,
   if you want acceleration - you may remove some line  in source
   code).
2. Photon has some errors in detecting  how  much bits  per pixel
   videomode has.
3. No  shared  libraries  yet.  We  need  manually  set  flag  to
   'configure' --disable-shared.
4. Due to Photon API limitation, flag SDL_HWSURFACE supported on-
   ly in case of desktop bpp is equal requested bpp in window mo-
   de.

Some building issues:

    Run configure script without x11 support, e.g.:

    a) for OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared

    b) without OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared    \
                --disable-video-opengl

    In test directory  also run  ./configure  script  without x11
support, e.g.:

    ./configure  --with-sdl-prefix=/usr/local      \
                 --with-sdl-exec-prefix=/usr/local \
                 --prefix=/usr/local --without-x
