Author Topic: Drawable to Image (Read 4353 times)

I want to draw a Drawable object on an Image, specificaly a String object on an Image. I know that this is on the roadmap, and is planned to be done. But I don't want to wait.

Basicaly what I want to do is to draw a text on an Image, so I was thinking on drawing a String on the Image, but any method should be fine, like using another library for drawing the text.
So, how could this be done? Or at least, can someone point me on the right direction for doing so?

Thanks in advance.

You could derive a class from sf::Drawable that contains a normal sf::Sprite and a sf::String.

I have thought doing so, but if I want to draw something over the image, the text wouldn't be affected.

Then you would need a second sprite that is transparent by default. When you draw something you draw on this sprite.

Rendering to an image is already implemented in the sfml2 branch.

Thanks, I will check the svn now

I have checked the sources of sfml2 branch, and I can't find how to make this. Can you give me a simple example?

Edit: I have found now how to do so, but I am having the message that RenderImage isn't supported by my system. Any fix for this?

What is your OS and graphics card?

RenderImage is widely supported on Windows, 50% on Linux and not implemented yet on Mac OS X.

I am using Windows XP SP3, and I have a pretty old PC. The graphic card is VIA/S3G UniChrome IGP - 32MB of memory.

Your last chance is to render your text to the screen and capture it :?
