Constructor Detail
- Texture
```
public Texture(PGraphicsOpenGL pg)
```
- Texture
```
public Texture(PGraphicsOpenGL pg,
 int width,
 int height)
```
  Creates an instance of PTexture with size width x height. The texture is initialized (empty) to that size.
  
  Parameters:
  
  width - int
  
  height - int
- Texture
```
public Texture(PGraphicsOpenGL pg,
 int width,
 int height,
 java.lang.Object params)
```
  Creates an instance of PTexture with size width x height and with the specified parameters. The texture is initialized (empty) to that size.
  
  Parameters:
  
  width - int
  
  height - int
  
  params - Parameters

Method Detail

init
```
public void init(int width,
 int height)
```
Sets the size of the image and texture to width x height. If the texture is already initialized, it first destroys the current OpenGL texture object and then creates a new one with the specified size.

Parameters:

width - int

height - int

init
```
public void init(int width,
 int height,
 Texture.Parameters params)
```
Sets the size of the image and texture to width x height, and the parameters of the texture to params. If the texture is already initialized, it first destroys the current OpenGL texture object and then creates a new one with the specified size.

Parameters:

width - int

height - int

params - GLTextureParameters
