Direct Known Subclasses:

IlvLatLonGrid, IlvMGRSGrid
```
public abstract class IlvAbstractBaseGrid
extends IlvManagerLayer
implements IlvManagerViewDecoration, IlvManagerLightViewDecoration
```
The base class to draw grids on top of an IlvManagerView. This class is abstract, but provides many coordinate related utilities and base properties. Subclasses must at least implement the paintGrid(Graphics2D, IlvTransformer)method. For example, the following code can be used to display an automatically scaled longitude/latitude grid.
```
   IlvManagerView view=new IlvManagerView();
   ...
   IlvLatLonGrid grid = new IlvLatLonGrid();
   grid.setAutoScaled(true);
   grid.setGridColor(Color.lightGray);
   grid.setTextColor(Color.blue);
   view.getManager().addLayer(grid);
 
```
To have a non printed grid use view.addViewDecoration(grid); If you want the grid to be printed, use instead: view.getManager().addLayer(grid);
Since:

JViews 7.5

```
public void draw(Graphics dst,
                 IlvManagerView v)

    Paints the grid in the specified view. Since JViews 8.1, to take advantage of layer caching, this method calls super.draw(). The actual drawing code is done in drawImpl(Graphics, IlvManagerView).
    
    Overrides:
    
    draw in class IlvManagerLayer
    
    Parameters:

    Draws the grid content in the specified view.
    Note: as updateViewParameters(IlvManagerView) is called for optimization issues, a grid will only be able to draw one at a time. This is true even if you are using multiple threads.
    
    Overrides:
    
    drawImpl in class IlvManagerLayer
    
    Parameters:

    Sets the distance between successive grid lines (if autoscaling is not activated). If autoscaling is activated, an heuristic algorithm will automatically change the step value.

public void setVisibleOnlyOnView(IlvManagerView visibleView)
```
    Forces the grid to be displayed only on the specified view. If the visibleView parameter is not null, the isVisible(IlvManagerView) method will only return true for this view. Use this method to prevent the grid from painting on an overview, for example.

                        boolean drawLine)
```
    Utility to draw a grid line and its label. The label will be drawn only if the line intersects the visible rectangle of the view.
    
    Parameters:
    
    dst - The Graphics to paint to.
    
    t - The IlvTransformer to use.
    
    p1 - The view related first point of the line
    
    p2 - The view related second point of the line.
    
    label - The label to draw.
    
    drawLine - If false, this method will only draw the eventual text.

                          String label)
```
    Utility to draw a label text.
    
    Parameters:
    
    dst - The Graphics to paint to.
    
    t - The IlvTransformer to use.

                        boolean horizontal,
                        int alignment)
```
    Utility to draw a label text.
    Parameters:
    
    g - The Graphics to paint to.
    
    point - Swing view coordinates of the text reference point.
    
    label - Can be either an AttributedCharacterIterator or a regular object.
    
    horizontal - true if the string must be horizontal.
    alignment - Indicates if the text is centered after or before the reference point. Alignment can be either:
    
    SwingConstants.CENTER
    SwingConstants.LEADING
    SwingConstants.TRAILING
  - getCoordinateTransformation
```
protected IlvCoordinateTransformation getCoordinateTransformation()
```
    Returns the transformation to use to transform view coordinates to geographic system.
    
    Returns:
    
    The coordinate transformation associated with the view.
  - getInverseCoordinateTransformation
```
protected IlvCoordinateTransformation getInverseCoordinateTransformation()
```
    Returns the transformation to use to transform geographic system to view coordinates.
    
    Returns:
    
    The inverse coordinate transformation associated with the view.
  - getViewScale
```
protected double getViewScale()
```
    Returns the current view scale.
    
    Returns:
    
    The scale of the view.
  - getViewTransformer
```
protected IlvTransformer getViewTransformer()
```
    Returns the current view transformer.
    
    Returns:
    
    The transformer of the view.
  - isLightPainting
```
protected boolean isLightPainting()
```
    This flag indicates grids to try to paint "lightly". This usually means not painting labels, or painting a larger scaled grid.
    
    Returns:
    
    true if painting is light.

  - updateTransforms
```
protected void updateTransforms(IlvManager m)
```
    Searches and updates the coordinate transformations to use, according to the coordinate system set on the manager.
    
    Parameters:
    
    m - Manager.
  - write
```
public void write(IlvOutputStream stream)
           throws IOException
```
    Writes the layer to an output stream. You should not call this method directly, but you may need to override it in a subclass of IlvManagerLayer to store your own information. If you override the method, you may call super.write(stream) after your own saving instructions. Calling the superclass method will dump the graphic objects stored in the layer.
    
    Specified by:
    
    write in interface IlvPersistentObject
    
    Overrides:
    
    write in class IlvManagerLayer
    
    Parameters:
    
    stream - the output stream
    
    Throws:
    
    IOException - thrown when an exception occurs during the write operation for this object.
    
    See Also:
    
    IlvManagerLayer.write(ilog.views.io.IlvOutputStream)
  - isTextVisible
```
public boolean isTextVisible()
```
    Returns true if the lines crossing the screen border should display text.
    
    Returns:
    
    Returns true if the lines crossing the screen border should display text.
  - setTextVisible
```
public void setTextVisible(boolean textVisible)
```
    Indicates whether the lines crossing screen border should display their lat/lon text.
    
    Parameters:
    
    textVisible - The visibility of text.
