public void paint(Graphics aGraphics,
                  int aRenderMode,
                  ILcdGXYContext aGXYContext)
```
    Description copied from interface: ILcdGXYPainter
    Displays the representation of the object in the given mode on the Graphics passed, taking into account the supplied context.
    The visual representation of an object depends on the context. Depending on the context (e.g. is the location covered by the view), an object may or may not have a representation. The context contains:
    - transformations which allow to compute the location in view space of points and bounds given in model, space
    - a pen which can connect points with a line or create arcs around a point,
    - the view for which the object's representation must be painted. This can be useful when the painted object depends on the scale of the view, or the presence of other layers in the view.
    - the current location(s) of the mouse or input device and the last location(s) the mouse or input device was pressed.
    The mode passed in this method indicates what part of the object must be painted, whether it should be painted as selected or not, and whether user interaction (via mouse movements) must be taken into account.
    
    When the mode passed contains either TRANSLATING, RESHAPING or CREATING, this method is also responsible for interpreting interaction on the representation of an object and modifying the representation of the object accordingly. The painter is not responsible for modifying the object itself, this is done by a corresponding ILcdGXYEditor . Implementations of ILcdGXYPainter and ILcdGXYEditor interfaces must be consistent for an object: the painter must display the result of the user interaction on the object, while the editor is responsible for modifying the object as a result of the user interaction. A good practice to ensure a consistent implementation is to implement both the ILcdGXYPainter and ILcdGXYEditor interfaces in a single class.
    
    When the mode passed includes SNAPS, the part of the representation which corresponds to the object returned as snap target by the method snapTarget must be painted in order to provide the user with a visual indication of the snap target.
    
    The Graphics passed in this method can be different from the Graphics returned by a view due to techniques such as double buffering (as applied in Swing). Basic drawing operations must always be performed on the Graphics passed as an argument in this method.
    Specified by:
    
    paint in interface ILcdGXYPainter
    
    Parameters:
    
    aGraphics - the Graphics on which the representation of the object is painted
    
    aRenderMode - the mode the object is represented in (see class documentation).
    
    aGXYContext - the ILcdGXYContext the drawing depends on.
  - isTouched
```
public boolean isTouched(Graphics aGraphics,
                         int aMode,
                         ILcdGXYContext aGXYContext)
```
    Description copied from interface: ILcdGXYPainter
    Checks if the representation of the object in the given mode is touched at the location as defined in the supplied context.
    The location that must be taken into account to check whether the representation is touched can be retrieved from the context passed with the methods ILcdGXYContext.getX() and ILcdGXYContext.getY(). If the check is part of an ongoing operation of user interaction, for example, when the mouse is being dragged, the location of the start of the operation can also be taken into account using the methods ILcdGXYContext.getDeltaX() and ILcdGXYContext.getDeltaY(). The context contains the transformations required to convert this location into the equivalent location in model space. Implementations of this interface usually follow either of the following patterns:
    - transform the location of the interaction back to model space and compare the coordinates with the object in model space.
    - transform the location to world space and compare with a world representation of the object. This forces the painter into caching a world representation of the object. Caching a view representation of an object is not very practical as it would have to change whenever the view's scale changes or when it is panned. A world representation of an object only changes when the view's XYWorldReference changes, which happens less frequently.
    As the mode influences the way an object is represented, it must also be taken into account when checking whether that representation is being touched. When the mode contains CREATING, RESHAPING or TRANSLATING which indicate that the object must be represented in a state for an ongoing operation, the location of the start of the operation may be taken into account as mentioned above. The painting result can take into account multiple locations, to respond to, for example, multi-touch input. When the mode contains SELECTED, the painter should also check if the non-selected representation is touched, since these are always painted on top of each other.
    
    The boundsSFCT is often used to speed up the performance of this method as a location outside these bounds can never touch the representation of the object.
    
    Note that this method does not give an indication of what part of the object is touched. It is up to the painter implementations to provide methods to make this distinction. The method does also not indicate what sensitivity must be applied when checking if an object is touched. It is up to the implementation to decide what should be the maximum distance between the location given in the context and the closest relevant point or area of the representation of the object.
    Specified by:
    
    isTouched in interface ILcdGXYPainter
    
    Parameters:
    
    aGraphics - the Graphics on which the representation of the object is painted
    
    aMode - the mode the object is represented in
    
    aGXYContext - contains the location of the interaction and the transformations to convert this location into model coordinates
    
    Returns:
    
    true if the representation of the object in the given mode is touched by the location as defined in the context passed, false otherwise

```
public void setStartResolutionFactor(double aFactor)
```
    Description copied from interface: ILcdRasterPainter
    
    Sets the highest pixel density (number of raster pixels per screen pixel) at which a raster is painted. If the pixel density is too high, only the raster outlines and tile outlines are painted (or a lower resolution level is chosen). This can avoid having to load a large raster to fill a relatively small view.

public void setStopResolutionFactor(double aFactor)
```
    Description copied from interface: ILcdRasterPainter
    
    Sets the lowest pixel density (number of raster pixels per screen pixel) at which a raster is painted. If the pixel density is too low, nothing is painted. This can avoid painting overly pixelated rasters.

```
public double getStartScale()
```
    Returns the start scale.
    
    Returns:

  - setStartScale
```
public void setStartScale(double aStartScale)
```
    As an alternative for the start resolution factor and stop resolution factor, this method and getStopScale() can be used for more intuitive control on when to paint a raster and when to paint the outline. When the internal scale of the view (ILcdGXYView.getScale() is smaller than the start scale, the outline will be painted in stead of the raster. The default value is 0. Warning: when the view scale is in between the start and stop scale, the start resolution factor and the stop resolution factor are still used as a second check. If you don't want interference from these two settings, set the start resolution factor to Double.POSITIVE_INFINITY and the stop resolution factor to 0.
    
    Parameters:
    
    aStartScale - The view scale at which one starts painting the raster rather that the outline (when zooming in).

public double getStopScale()
```
    Returns the stop scale.

    setStopScale(double)
  - setStopScale
```
public void setStopScale(double aStopScale)
```
    As an alternative for the start resolution factor and stop resolution factor, this method and getStartScale() can be used for more intuitive control on when to paint a raster. When the internal scale of the view (ILcdGXYView.getScale() is larger than the stop scale, the raster won't be painted. The default value is Double.POSITIVE_INFINITY.

  - getRGBImageFilter
```
public RGBImageFilter getRGBImageFilter()
```
    Returns the optional filter that is applied to painted rasters.
  - setTransparency
```
public void setTransparency(float aTransparency)
```
    Description copied from interface: ILcdRasterPainter
    
    Sets the transparency factor that is applied to painted rasters. It is an alpha value between 0 and 1, with 0 being perfectly transparent, and 1 (the default) being perfectly opaque.

  - setBrightness
```
public void setBrightness(float aBrightness)
```
    Description copied from interface: ILcdRasterPainter
    
    Sets the brightness factor that is applied to painted rasters. It is a positive value, with 0 being black, and 1 (the default) being the original brightness. Values larger than 1 are allowed, although bright colors may then be clamped to white. Some standard implementations of this interface additionally provide a contrast setting (gamma correction) that does not have this problem.

  - setContrast
```
public void setContrast(float aContrast)
```
    Sets the gamma correction that is applied to painted rasters. A value of 1 (the default) leaves the contrast unchanged. A value larger than 1 enhances the contrast of dark colors by making them brighter, while a value smaller than 1 enhances the contrast of bright colors by making them darker.

  - densityCheck
```
public int densityCheck(ILcdRaster aRaster,
                        ILcdGXYContext aGXYContext)
```
    Determines if the raster density of the given raster is suitable for processing or analysis in the given context, considering the start resolution factor and the stop resolution factor, and the forced painting flag.
    The raster density may be considered too high, meaning that too many raster pixels are mapped onto a single view pixel. This would typically make lazy loading the raster data disproportionally slow.
    Conversely, the raster density may be considered too low, meaning that a single raster pixel is mapped onto too many view pixels. This would typically make the raster data insufficiently accurate to work with.
    
    Parameters:
    
    aRaster - the raster to be processed or analyzed.
    
    aGXYContext - the context that contains the model of the raster, the model-to-world transformation, and the view-to-world transformation.
    
    Returns:
    
    DENSITY_TOO_HIGH, DENSITY_OK, or DENSITY_TOO_LOW.

                        Graphics aGraphics)
```
    Determines if the pixel density of the given raster is suitable for display, in the given context, considering the start resolution factor and the stop resolution factor, and the forced painting flag.
    The raster's pixel density may be considered too high, meaning that too many raster pixels are mapped onto a single view pixel. This would typically make lazy loading the raster data disproportionally slow.
    Conversely, the raster's pixel density may be considered too low, meaning that a single raster pixel is mapped onto too many view pixels. This would typically make the raster data insufficiently accurate to display.
    
    Parameters:
    
    aRaster - the raster to be displayed.
    
    aGXYContext - the context that contains the model of the raster, the model-to-world transformation, and the view-to-world transformation.
    
    aGraphics - the Graphics instance on which the raster is to be painted.
    
    Returns:
    
    DENSITY_TOO_HIGH, DENSITY_OK, or DENSITY_TOO_LOW.

```
    Computes the ratio between the given raster's pixel density and the ideal display density for the given context.
    
    Parameters:
    
    aRaster - the raster to be displayed.
    
    aGXYContext - the context that contains the model of the raster, the model-to-world transformation, and the view-to-world transformation.

                               throws TLcdNoBoundsException
```
    Computes the ideal pixel density that a raster should have for display in the given context. The ideal density is a number of pixels per unit of area, expressed in model coordinates, such that one model pixel maps onto one view pixel, on average. This ideal density can serve as a reference for an actual raster with a pixel density that may or may not be ideal.
    
    Parameters:
    
    aModelBounds - the area of the raster to be displayed, expressed in model coordinates.
    
    aGXYContext - the context that contains the model of the raster, the model-to-world transformation, and the view-to-world transformation.
