I'm writing a 2D program and I want to be able to write text to the screen that is quite small, but highly visible upon a background which is a real picture. Currently, I'm just using the text command to place text onto a real-life picture. Choosing the colours for the text on a picture that I know is relatively easy, so long as the picture doesn't contain any drastic contrast changes. What I want to do is be able to place any coloured text onto a picture chosen by the player that is easily visible and doesn't get lost in the backdrop.

The best way I can think to do this would be to have a semi-transparent grey area behind the text that would allow the user to faintly see the picture backdrop they are using. Come to think of it, this is seen in the Championship Manager games.

Sorry if this is a little confusing, I'll try and post of pics of what I've already achieved a bit later.

Hope someone has some advice?

Hmm you could try ghosting a sprite or a plane which would work for that little ghost effect.

I haven't got my own website so I can't post any pics of what I've already done.

Thanks for the reply RPGamer. I thought of doing it with a plane but I really want to keep this project in 2D, it'll just be a lot easier to code all of the screens, menus and buttons that way.
I think what I'll have to do is create a bitmap with enough black spaces to be considered semi-transparent and then set the transparency flag when using paste image.
Does anyone have an idea how to create the bitmap though?

There isn't some simple command I've over-looked that would solve this is there?

Semi-Transparent is also known as Translucency.
