  - getWidth
```
public final int getWidth()
```
    Description copied from class: MapCanvas
    
    Gets the width of this canvas
    
    Specified by:
    
    getWidth in class MapCanvas
    
    Returns:
    
    canvas width
  - getHeight
```
public final int getHeight()
```
    Description copied from class: MapCanvas
    
    Gets the height of this canvas
    
    Specified by:
    
    getHeight in class MapCanvas
    
    Returns:
    
    canvas height
  - getBuffer
```
public final byte[] getBuffer()
```
    Description copied from class: MapCanvas
    Gets the backing color data buffer for all the data in this canvas. This buffer is not guaranteed to be immutable. For an immutable buffer, use MapCanvas.readPixels() instead. This data is formatted in such a way that:
    - The first color in the array is pixel (0, 0)
    - Satisfies condition index = x + y * width
    - The size of the buffer equals (width * height)
    Specified by:
    
    getBuffer in class MapCanvas
    
    Returns:
    
    raw color byte buffer
  - next
```
public MapDisplay.Layer next()
```
    Gets the layer that follows this one, creating a new layer if required. The next layer is higher in the z-buffer, meaning it overlaps this layer.
    
    Returns:
    
    next layer
  - previous
```
public MapDisplay.Layer previous()
```
    Gets the layer that precedes this one, creating a new layer if required. The previous layer is lower in the z-buffer, meaning that this layer overlaps that one.
    
    Returns:
    
    previous layer
  - writePixelsFill
```
public MapCanvas writePixelsFill(int x,
                                 int y,
                                 int w,
                                 int h,
                                 byte color)
```
    Description copied from class: MapCanvas
    
    Fills a rectangular area in this canvas with a single color. No color blending is performed and any original pixels are replaced. No depth buffering is performed, either.
    
    Overrides:
    
    writePixelsFill in class MapCanvas
    
    Parameters:
    
    x - - coordinate of the top-left corner of the area
    
    y - - coordinate of the top-left corner of the area
    
    w - - width of the area
    
    h - - height of the area
    
    color - to fill
    
    Returns:
    
    this canvas
  - writePixel
```
public final void writePixel(int x,
                             int y,
                             byte color)
```
    Description copied from class: MapCanvas
    
    Updates the pixel color of a single pixel. No color blending or depth buffering logic is performed.
    
    Specified by:
    
    writePixel in class MapCanvas
    
    Parameters:
    
    x - - coordinate of the pixel
    
    y - - coordinate of the pixel
    
    color - to draw
  - readPixel
```
public final byte readPixel(int x,
                            int y)
```
    Description copied from class: MapCanvas
    
    Reads the pixel color value of a single pixel
    
    Specified by:
    
    readPixel in class MapCanvas
    
    Parameters:
    
    x - - coordinate of the pixel
    
    y - - coordinate of the pixel
    
    Returns:
    
    color at this pixel, 0 for transparent
  - readPixels
```
public byte[] readPixels(int x,
                         int y,
                         int w,
                         int h,
                         byte[] dst_buffer)
```
    Description copied from class: MapCanvas
    Reads the raw pixel color data for a particular area in this canvas. This is guaranteed to be a copy of the actual data. This data is formatted in such a way that:
    - The first color in the array is pixel (0, 0)
    - Satisfies condition index = x + y * width
    - The size of the buffer equals (width * height)
    Overrides:
    
    readPixels in class MapCanvas
    
    Parameters:
    
    x - - coordinate of the top-left corner of the area
    
    y - - coordinate of the top-left corner of the area
    
    w - - width of the area
    
    h - - height of the area
    
    dst_buffer - - buffer to write the pixels to
    
    Returns:
    
    dst_buffer input parameter
