@Deprecated public class TLcdGRIBRasterPainter extends ALcdGXYPainter implements ILcdGXYPainter
ILcdGXYPainter
paints ILcdMultivaluedRaster
objects from models that have a TLcdMultivaluedRasterModelDescriptor
containing TLcdGRIBModelDescriptor
instances.
It paints GRIB icons at regular grid locations in the view. The grid
spacing and the GRIB icon can be specified.
This painter is much like the TLcdMultivaluedRasterPainter
, except
that it paints GRIB icons, which work with double values instead of integer
values.

ILcdGXYPainter
Setting the object on the painter may have an effect on the internal state of the painter, for example, the color to use.
When the object is set to a painter, the context parameter in subsequent calls to methods in this class must contain a layer that contains this object and for which the painter for this object is this painter.

public void paint(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext)
ILcdGXYPainter
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:
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.

ILcdGXYPainter
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:
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.

If this method returns without exception the bounds argument must encompass the representation of the object. A point outside the bounds will not be contained within the painted object.
The bounds returned in this method can be seen as the equivalent in the view space of the bounds in the model
space for ILcdBounded
objects.
