public class Image
extends Object

Contains a texture and its dimensions.

Constructor Summary

Image(BufferedImage image)
Creates an image from the supplied source AWT image.

Image(Texture2D texture)
Creates an image from an existing texture.

Image(Texture2D texture, int width, int height)

Method Summary

static void	configureTexture(Texture2D texture) Configures a texture for use as an image.
int	getHeight() Returns the height of this image.
Texture2D	getTexture(Renderer renderer) Returns a reference to the image texture, loading it if necessary.
int	getWidth() Returns the width of this image.
void	load(Renderer renderer, int format) Loads the image into a texture (this is called automatically when first used and need only be called manually if a specific format is desired).

void	render(Renderer renderer, int tx, int ty, float alpha) Renders this image at the specified coordinates.
void	render(Renderer renderer, int tx, int ty, int twidth, int theight, float alpha) Renders this image at the specified coordinates, scaled to the specified size.
void	render(Renderer renderer, int sx, int sy, int swidth, int sheight, int tx, int ty, float alpha) Renders a region of this image at the specified coordinates.
void	render(Renderer renderer, int sx, int sy, int swidth, int sheight, int tx, int ty, int twidth, int theight, Color4f color, float alpha) Renders a region of this image at the specified coordinates, scaled to the specified size, in the specified color.
void	render(Renderer renderer, int sx, int sy, int swidth, int sheight, int tx, int ty, int twidth, int theight, float alpha) Renders a region of this image at the specified coordinates, scaled to the specified size.
