ICanvas (Jzy3d API 1.0.3 API)

All Known Subinterfaces:

IScreenCanvas

All Known Implementing Classes:

CanvasAWT, CanvasNewtAwt, CanvasSwing, OffscreenCanvas, VoidCanvas
```
public interface ICanvas
```
A ICanvas represent the target component for rendering OpenGL. It might be displayed on the screen in a GUI (IScreenCanvas), or simply be an offscreen component able to export an image OffscreenCanvas.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`addKeyController(Object o)` A generic interface for mouse listener to remain Windowing toolkit independant.
`void`	`addMouseController(Object o)` A generic interface for mouse listener to remain Windowing toolkit independant.
`void`	`dispose()` Performs all required cleanup when destroying a Canvas.
`void`	`forceRepaint()` Invoked when a user requires the Canvas to be repainted (e.g. a non 3d layer has changed).
`String`	`getDebugInfo()`
`com.jogamp.opengl.GLDrawable`	`getDrawable()` Returns the GLDrawable associated with the canvas
`Renderer3d`	`getRenderer()`
`int`	`getRendererHeight()` Returns the renderer's height, i.e. the display height.
`int`	`getRendererWidth()` Returns the renderer's width, i.e. the display width.
`View`	`getView()` Returns a reference to the held view.
`void`	`removeKeyController(Object o)` A generic interface for key listener to remain Windowing toolkit independant. * Implementation of this method should simply cast the input assuming it will correspond to canvas-compatible key listener.
`void`	`removeMouseController(Object o)` A generic interface for key listener to remain Windowing toolkit independant.
`com.jogamp.opengl.util.texture.TextureData`	`screenshot()` Returns an image with the current renderer's size
`com.jogamp.opengl.util.texture.TextureData`	`screenshot(File file)`
`void`	`setPixelScale(float[] scale)` Defines pixel scale.

- Method Detail
  - getView
```
View getView()
```
    Returns a reference to the held view.
  - getDrawable
```
com.jogamp.opengl.GLDrawable getDrawable()
```
    Returns the GLDrawable associated with the canvas
  - getRendererWidth
```
int getRendererWidth()
```
    Returns the renderer's width, i.e. the display width.
  - getRendererHeight
```
int getRendererHeight()
```
    Returns the renderer's height, i.e. the display height.
  - getRenderer
```
Renderer3d getRenderer()
```
  - forceRepaint
```
void forceRepaint()
```
    Invoked when a user requires the Canvas to be repainted (e.g. a non 3d layer has changed).
  - screenshot
```
com.jogamp.opengl.util.texture.TextureData screenshot()
```
    Returns an image with the current renderer's size
  - screenshot
```
com.jogamp.opengl.util.texture.TextureData screenshot(File file)
                                               throws IOException
```
    Throws:
    
    IOException
  - dispose
```
void dispose()
```
    Performs all required cleanup when destroying a Canvas.
  - addMouseController
```
void addMouseController(Object o)
```
    A generic interface for mouse listener to remain Windowing toolkit independant. Implementation of this method should simply cast the input assuming it will correspond to canvas-compatible mouse listener.
  - addKeyController
```
void addKeyController(Object o)
```
    A generic interface for mouse listener to remain Windowing toolkit independant. Implementation of this method should simply cast the input assuming it will correspond to canvas-compatible mouse listener.
  - removeMouseController
```
void removeMouseController(Object o)
```
    A generic interface for key listener to remain Windowing toolkit independant. Implementation of this method should simply cast the input assuming it will correspond to canvas-compatible key listener.
  - removeKeyController
```
void removeKeyController(Object o)
```
    A generic interface for key listener to remain Windowing toolkit independant. * Implementation of this method should simply cast the input assuming it will correspond to canvas-compatible key listener.
  - getDebugInfo
```
String getDebugInfo()
```
  - setPixelScale
```
void setPixelScale(float[] scale)
```
    Defines pixel scale. On MacOS Retina displays, a X*Y chart uses a (X*2)*(Y*2) viewport. This makes some calculation based on viewport (such as Camera.screenToModel(com.jogamp.opengl.GL, com.jogamp.opengl.glu.GLU, org.jzy3d.maths.Coord3d) output wrong result. When running on Retina display, those two options fixed buggy mouse selections on Retina:
    - setPixelScale(new float[]{0.5f,0.5f})
    - setPixelScale(new float[] { ScalableSurface.IDENTITY_PIXELSCALE, ScalableSurface.IDENTITY_PIXELSCALE })
