Title: Drawing Shapes on Images
Post by: Uzaku on October 25, 2011, 01:57:22 pm

Hey,
I want to create an Image, with lines, Basically a very simple Chessboard.
So i created 2 sf::Shape:Line objects one vertical and one horizontal.
But then i noticed I cant copy them to the image.
And now my question is, is there any way to copy it, that i didn't see, or will i have to generate them myself by changing the certain pixel?

greetings Uzaku

With SFML 2, you can use sf::RenderTexture.

In SFML 1, the only way I know is a workaround via sf::RenderWindow's screenshot capabilities. But maybe it's easier to calculate the pixels. I think you can even use only a small image with as many pixels as fields, and scale the sprite accordingly.
