Sorry if I do not fully understand you, but if you are going to blit an 
invisible surface, why bother to try to display it at all?

If you are using Windows your pixel format will be tipically RGBA, 8 bits for 
every of the four components, stored in little endian format. However it is 
better to do as the example shown in the documentation and mind the endianess 
of your system.
