- Method Detail
  - width
```
int width()
```
    Gets the width of the drawable surface, in pixels.
  - height
```
int height()
```
    Gets the height of the drawable surface, in pixels.
  - screenHeight
```
int screenHeight()
```
    Gets the height of the available screen real-estate, in pixels.
  - screenWidth
```
int screenWidth()
```
    Gets the width of the available screen real-estate, in pixels.
  - scaleFactor
```
float scaleFactor()
```
    Returns the display scale factor. This will be 1 except on HiDPI devices that have been configured to use HiDPI mode, where it will probably be 2, but could be some other scale depending on how things were configured when initializing the platform.
  - rootLayer
```
GroupLayer rootLayer()
```
    Returns the root of the scene graph. When layers are added to this layer, they become visible on the screen.
  - ctx
```
GLContext ctx()
```
    Returns the GL context on platforms that use GL, null otherwise. This is used for creating custom shaders.
  - gl20
```
GL20 gl20()
```
    Returns a reference to the GL context. WARNING: this is an experimental, not well tested feature. It works on the Java, HTML and Android backends. It may change completely. Consider yourself warned.
  - createGroupLayer
```
GroupLayer createGroupLayer()
```
    Creates a group layer.
  - createGroupLayer
```
GroupLayer.Clipped createGroupLayer(float width,
                                  float height)
```
    Creates a clipped group layer, with the initial clipping size.
  - createImmediateLayer
```
ImmediateLayer.Clipped createImmediateLayer(int width,
                                          int height,
                                          ImmediateLayer.Renderer renderer)
```
    Creates an immediate layer that is clipped to the specified rectangular region.
    
    Parameters:
    width - the horizontal extent of the layer's drawable region.
    height - the vertical extent of the layer's drawable region.
  - createImmediateLayer
```
ImmediateLayer createImmediateLayer(ImmediateLayer.Renderer renderer)
```
    Creates an unclipped immediate layer. This layer may draw anywhere on the framebuffer, though its rendering operations will be transformed appropriately, based on the layer's current transform.
  - createImageLayer
```
ImageLayer createImageLayer()
```
    Creates an image layer with no configured image. Configure the image like so: createImageLayer().setImage(image).
  - createImageLayer
```
ImageLayer createImageLayer(Image image)
```
    Creates an image layer with the supplied image.
  - createSurfaceLayer
```
@Deprecated
SurfaceLayer createSurfaceLayer(float width,
                                         float height)
```
    Deprecated. Use createSurface(float, float) and createImageLayer().
  - createImage
```
CanvasImage createImage(float width,
                      float height)
```
    Creates an image that can be painted using the Canvas interface.
  - createSurface
```
SurfaceImage createSurface(float width,
                         float height)
```
    Creates an image that can be rendered into using the Surface interface.
  - createLinearGradient
```
Gradient createLinearGradient(float x0,
                            float y0,
                            float x1,
                            float y1,
                            int[] colors,
                            float[] positions)
```
    Creates a linear gradient fill pattern. (x0, y0) and (x1, y1) specify the start and end positions, while (colors, positions) specifies the list of color stops.
  - createRadialGradient
```
Gradient createRadialGradient(float x,
                            float y,
                            float r,
                            int[] colors,
                            float[] positions)
```
    Creates a radial gradient fill pattern. (x0, y0, r) specifies the circle covered by this gradient, while (colors, positions) specifies the list of color stops.
  - createFont
```
Font createFont(String name,
              Font.Style style,
              float size)
```
    Creates a font with the specified configuration.
  - layoutText
```
TextLayout layoutText(String text,
                    TextFormat format)
```
    Lays out the supplied text using the specified format. The text may subsequently be rendered on a canvas via Canvas.fillText(TextLayout,float,float).
