ola,
      
yes, i saw the latest svn version can _compile_
with latest gem cvs ( some sport involved there ),
but pdp2gem and pix_2pdp do not work,
i get black or no-output in both case.
    


    
what i see from analyzing the code
is that the function :

   glReadPixels(m_x, m_y, m_image->xsize, m_image->ysize,
                m_image->format, m_image->type, m_image->data);

  with :

  m_image->type  = GL_UNSIGNED_BYTE;
  m_image->format = GL_RGBA;

returns a black image ( all bytes are 0 ),
so something has changed here?

saludos,
sevy
