Hi, do you know the pixel format of the data you have?
Do you get scanlines that you wanna pass to an SDL::Surface? Or do you
get just the whole image?
May I invite you to irc? Would be much easier than mails... #sdl at
irc.perl.org.

Hi FROGGS,
I was on IRC and got a lot of help, thank you.
The data is RAW BGR/RGB or RGBA data from the network i.e. VNC rectangle
packets.
The problem I had was it was not obvious how to put this "raw" data into
a surface so that it could be blitted.
The solution (thanks to Scott Walters) was to get the get_pixels_ptr and
fill the area of the surface directly as follows:
$pixels_ptr=$surface->get_pixels_ptr();
substr $$pixels_ptr, 0, length($data), $data;
# $data=raw RGB data.
I hope this information helps others.
Albert
