Texture (PlayN Core 2.0.2 API)

java.lang.Object
- playn.core.TileSource
- - playn.core.Tile
  - - playn.core.Texture

All Implemented Interfaces:

java.lang.AutoCloseable, react.Closeable
```
public class Texture
extends Tile
implements react.Closeable
```
A handle to an OpenGL texture. A texture is also a Tile which contains the entire texture, which allows rendering methods to operate uniformly on tiles.

- Field Detail
  - id
```
public final int id
```
    The GL texture handle.
  - config
```
public final Texture.Config config
```
    This texture's configuration.
  - pixelWidth
```
public final int pixelWidth
```
    The width of this texture in pixels.
  - pixelHeight
```
public final int pixelHeight
```
    The height of this texture in pixels.
  - scale
```
public final Scale scale
```
    The scale factor used by this texture.
  - displayWidth
```
public final float displayWidth
```
    The width of this texture in display units.
  - displayHeight
```
public final float displayHeight
```
    The height of this texture in display units.

public Texture(Graphics gfx,
               int id,
               Texture.Config config,
               int pixWidth,

```
- Method Detail
  - nextPOT
```
public static int nextPOT(int value)
```
    Returns next largest power of two, or value if value is already a POT. Note: this is limited to values less than 0x10000.
  - reference
```
public void reference()
```
    Increments this texture's reference count. NOOP unless Texture.Config.managed.
  - release
```
public void release()
```
    Decrements this texture's reference count. If the reference count of a managed texture goes to zero, the texture is disposed (and is no longer usable).
  - update
```
public void update(Image image)
```
    Uploads image to this texture's GPU memory. image must have the exact same size as this texture and must be fully loaded. This is generally useful for updating a texture which was created from a canvas when the canvas has been changed.
  - tile
```
public Tile tile(pythagoras.f.IRectangle region)
```
    Returns an instance that can be used to render a sub-region of this texture.
  - tile
```
public Tile tile(float x,
                 float y,
                 float width,
                 float height)
```
    Returns an instance that can be used to render a sub-region of this texture.
  - disposed
```
public boolean disposed()
```
    Returns whether this texture is been disposed.
  - disposeSlot
```
public react.UnitSlot disposeSlot()
```
    Returns a Slot that will dispose this texture when triggered.
    This is useful when you want to manually bind the lifecycle of an unmanaged texture to the lifecycle of a layer. Simply `layer.onDisposed(texture.disposeSlot())`.
