[SDL] Writing directly on screen

[Edward Byard]

If you mean as a way to just display text over, say, a viewed webpage, then not really.

SDL is intended to work as an executable, independant program (is this making any sense?!) either as a Windows app or under some flavour of Linux.

I guess you could grab the current screen data (somehow) and then overlay your text on it, under SDL, using a full-screen mode, and should the user move the mouse (for instance) then the SDL app would exit. Possible but quite tricky.

Hope this helps.

Hi!

I'm looking for a cross-platform way to flash text on the screen. I
want to experiment with the effects flashed messages can have on the
user, much like the 'Eat Popcorn' movie subliminals of the 70s but
with self-chosen messages, e.g. 'I am an incredibly prolific hacker'.

Technically, this means overlaying text (and possibly graphics) over
the screen as a whole and removing it again, without interfering
with functionality at all.

Could SDL be used for this?

Carlo
