/* Target for off-screen 2D rendering into an image.
|
||||||
|
*
|
||||||
|
* sf::RenderImage is the little brother of sf::RenderWindow.
|
||||||
|
*
|
||||||
|
* It implements the same 2D drawing and OpenGL-related functions (see their base class sf::RenderTarget for
|
||||||
|
* more details), the difference is that the result is stored in an off-screen image rather than being show in a window.
|
||||||
|
*
|
||||||
|
* Rendering to an image can be useful in a variety of situations:
|
||||||
|
*
|
||||||
|
* - precomputing a complex static image (like a level's background from multiple tiles)
|
||||||
|
* - applying post-effects to the whole scene with shaders
|
||||||
|
* - creating a sprite from a 3D object rendered with OpenGL
|
||||||
|
* - etc.
|
||||||
|
*
|
||||||
|
* Usage example:
|
||||||
|
*
|
||||||
|
* # First of all: make sure that rendering to image is supported
|
||||||
|
* if SFML::RenderImage.available? == false
|
||||||
|
* # Handle error
|
||||||
|
* end
|
||||||
|
*
|
||||||
|
* # Create a new render-window
|
||||||
|
* window = SFML::RenderWindow.new( SFML::VideoMode.new(800, 600), "SFML window" )
|
||||||
|
*
|
||||||
|
* # Create a new render-image
|
||||||
|
* image = SFML::RenderImage.new
|
||||||
|
* if image.create( 500, 500 ) == false
|
||||||
|
* # Handle error
|
||||||
|
* end
|
||||||
|
*
|
||||||
|
* # The main loop
|
||||||
|
* while window.open?
|
||||||
|
* # Event processing
|
||||||
|
* # ...
|
||||||
|
*
|
||||||
|
* # Clear the whole image with red color
|
||||||
|
* image.clear( SFML::Color::Red )
|
||||||
|
*
|
||||||
|
* # Draw stuff to the image
|
||||||
|
* image.draw( sprite ) # sprite is a SFML::Sprite
|
||||||
|
* image.draw( shape ) # shape is a SFML::Shape
|
||||||
|
* image.draw( text ) # text is a SFML::Text
|
||||||
|
*
|
||||||
|
* # We're done drawing to the image
|
||||||
|
* image.display()
|
||||||
|
*
|
||||||
|
* # Now we start rendering to the window, clear it first
|
||||||
|
* window.clear()
|
||||||
|
*
|
||||||
|
* # Draw the image
|
||||||
|
* sprite = SFML::Sprite.new( image.getImage() )
|
||||||
|
* window.draw( sprite )
|
||||||
|
*
|
||||||
|
* # End the current frame and display its contents on screen
|
||||||
|
* window.display()
|
||||||
|
* end
|
||||||
|
*
|
||||||
|
* Like SFML::RenderWindow, SFML::RenderImage is still able to render direct OpenGL stuff. It is even possible to mix
|
||||||
|
* together OpenGL calls and regular SFML drawing commands. If you need a depth buffer for 3D rendering, don't
|
||||||
|
* forget to request it when calling SFML::RenderImage#create.
