public class YDisplayLayer
extends Object
```
YDisplayLayer Class: Interface for drawing into display layers, obtained by calling display.get_displayLayer. Each DisplayLayer represents an image layer containing objects to display (bitmaps, text, etc.). The content is displayed only when the layer is active on the screen (and not masked by other overlapping layers).

```
public int reset()
          throws YAPI_Exception
```
    Reverts the layer to its initial state (fully transparent, default settings). Reinitializes the drawing pointer to the upper left position, and selects the most visible pen color. If you only want to erase the layer content, use the method clear() instead.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - clear
```
public int clear()
          throws YAPI_Exception
```
    Erases the whole content of the layer (makes it fully transparent). This method does not change any other attribute of the layer. To reinitialize the layer attributes to defaults settings, use the method reset() instead.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - selectColorPen
```
public int selectColorPen(int color)
                   throws YAPI_Exception
```
    Selects the color to be used for all subsequent drawing functions, for filling as well as for line and text drawing. To select a different fill and outline color, use selectFillColor and selectLineColor. The pen color is provided as an RGB value. For grayscale or monochrome displays, the value is automatically converted to the proper range.
    
    Parameters:
    
    color - : the desired pen color, as a 24-bit RGB value
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - selectGrayPen
```
public int selectGrayPen(int graylevel)
                  throws YAPI_Exception
```
    Selects the pen gray level for all subsequent drawing functions, for filling as well as for line and text drawing. To select a different fill and outline color, use selectFillColor and selectLineColor. The gray level is provided as a number between 0 (black) and 255 (white, or whichever the lightest color is). For monochrome displays (without gray levels), any value lower than 128 is rendered as black, and any value equal or above to 128 is non-black.
    
    Parameters:
    
    graylevel - : the desired gray level, from 0 to 255
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.

```
public int selectEraser()
                 throws YAPI_Exception
```
    Selects an eraser instead of a pen for all subsequent drawing functions, except for bitmap copy functions. Any point drawn using the eraser becomes transparent (as when the layer is empty), showing the other layers beneath it.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error

```
    Selects the color to be used for filling rectangular bars, discs and polygons. The color is provided as an RGB value. For grayscale or monochrome displays, the value is automatically converted to the proper range. You can also use the constants FG_INK to use the default drawing colour, BG_INK to use the default background colour, and NO_INK to disable filling.
    
    Parameters:
    
    color - : the desired drawing color, as a 24-bit RGB value, or one of the constants NO_INK, FG_INK or BG_INK

    YAPI.SUCCESS if the call succeeds.

public int setConsoleBackground(int bgcol)
                         throws YAPI_Exception
```
    Sets up the background color used by the clearConsole function and by the console scrolling feature.
    
    Parameters:
    
    bgcol - : the background gray level to use when scrolling (0 = black, 255 = white), or -1 for transparent
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - setConsoleWordWrap
```
public int setConsoleWordWrap(boolean wordwrap)
                       throws YAPI_Exception
```
    Sets up the wrapping behavior used by the consoleOut function.
    
    Parameters:
    
    wordwrap - : true to wrap only between words, false to wrap on the last column anyway.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - clearConsole
```
public int clearConsole()
                 throws YAPI_Exception
```
    Blanks the console area within console margins, and resets the console pointer to the upper left corner of the console.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - setLayerPosition
```
public int setLayerPosition(int x,
                            int y,
                            int scrollTime)
                     throws YAPI_Exception
```
    Sets the position of the layer relative to the display upper left corner. When smooth scrolling is used, the display offset of the layer is automatically updated during the next milliseconds to animate the move of the layer.
    
    Parameters:
    
    x - : the distance from left of display to the upper left corner of the layer
    
    y - : the distance from top of display to the upper left corner of the layer
    
    scrollTime - : number of milliseconds to use for smooth scrolling, or 0 if the scrolling should be immediate.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - hide
```
public int hide()
         throws YAPI_Exception
```
    Hides the layer. The state of the layer is preserved but the layer is not displayed on the screen until the next call to unhide(). Hiding the layer can positively affect the drawing speed, since it postpones the rendering until all operations are completed (double-buffering).
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - unhide
```
public int unhide()
           throws YAPI_Exception
```
    Shows the layer. Shows the layer again after a hide command.
    
    Returns:
    
    YAPI.SUCCESS if the call succeeds.
    
    Throws:
    
    YAPI_Exception - on error
  - get_display
```
public YDisplay get_display()
```
    Gets parent YDisplay. Returns the parent YDisplay object of the current YDisplayLayer.
    
    Returns:
    
    an YDisplay object
  - get_displayWidth
```
public int get_displayWidth()
                     throws YAPI_Exception
```
    Returns the display width, in pixels.
    
    Returns:
    
    an integer corresponding to the display width, in pixels
    
    Throws:
    
    YAPI_Exception - on error
  - get_displayHeight
```
public int get_displayHeight()
                      throws YAPI_Exception
```
    Returns the display height, in pixels.
    
    Returns:
    
    an integer corresponding to the display height, in pixels
    
    Throws:
    
    YAPI_Exception - on error
  - get_layerWidth
```
public int get_layerWidth()
                   throws YAPI_Exception
```
    Returns the width of the layers to draw on, in pixels.
    
    Returns:
    
    an integer corresponding to the width of the layers to draw on, in pixels
    
    Throws:
    
    YAPI_Exception - on error
  - get_layerHeight
```
public int get_layerHeight()
                    throws YAPI_Exception
```
    Returns the height of the layers to draw on, in pixels.
    
    Returns:
    
    an integer corresponding to the height of the layers to draw on, in pixels
    
    Throws:
    
    YAPI_Exception - on error
  - resetHiddenFlag
```
public int resetHiddenFlag()
```
