| IlvDefaultPointRenderer::IlvDefaultPointRenderer | ( | IlvDisplay * | display | ) |
Creates an instance of the renderer.
| display | The display. |
| IlvDefaultPointRenderer::IlvDefaultPointRenderer | ( | const IlvDefaultPointRenderer & | source | ) |
Creates an IlvDefaultPointRenderer by copying an existing one.
| source | The object to be copied. |
| IlvColor* IlvDefaultPointRenderer::getForeground | ( | ) | const |
Returns the foreground color used to draw the marker.
IlvColor that should not be modified, because it can potentially be shared by other objects. However, it is possible to lock it if an other object has to use it. | IlUShort IlvDefaultPointRenderer::getLineWidth | ( | ) | const |
Returns the line width.

Translates an IlvMapFeature into a graphic object.
If the targetMapInfo has a non-null projection, or a projection that is not an instance of IlvUnknownProjection, the graphic object is projected to the projection system of targetMapInfo. Otherwise, only the map adapter of targetMapInfo is used to convert the feature coordinate into the manager coordinate system.
| feature | The map feature to be translated. |
| targetMapInfo | This parameter specifies the projection in which the graphic object must be returned. If this projection is not defined (targetMapInfo.getProjection() is NULL), the graphic object is returned to the projection of the map feature (only the map adapter is used) |
| status | Is set to an error code if the renderer cannot process the map feature (most of the time, because the renderer does not support the feature geometry, but it can also indicate that a projection error occurred). |
IlvGraphic or a null pointer if a severe error occurred. Implements IlvFeatureRenderer.
| void IlvDefaultPointRenderer::setForeground | ( | IlvColor * | color | ) |
Sets the foreground color of the marker.
The foreground color is used if there is no pattern or if there is a non-color pattern.
setPalette. | color | The foreground color used to draw the marker. |
| IlvMapsError IlvDefaultPointRenderer::setForeground | ( | const char * | colorName | ) |
Sets the foreground color of the marker.
It can be a predefined color or the string can have the syntax "#RRGGBB" in hexadecimal. The foreground color is used if there is no pattern or if there is a non-color pattern.
setPalette. | colorName | The name of the color. |
IlvMapsError::NoError() or IlvMaps::IllegalArgument() if the color name cannot be translated into a color. | void IlvDefaultPointRenderer::setLineWidth | ( | IlUShort | lineWidth | ) |
Sets the line width for the marker lines.
If the value is greater than 0, then the lines will be drawn using the fill pattern if any.
setPalette. | lineWidth | The new line width. |
| void IlvDefaultPointRenderer::setMarkerSize | ( | IlUShort | markerSize | ) |
Sets the size of the marker produced by this renderer.
| markerSize | The size of the marker. |
| void IlvDefaultPointRenderer::setMarkerType | ( | IlvMarkerType | markerType | ) |
Sets the marker type used by this renderer.
| markerType | The marker type. |
| void IlvDefaultPointRenderer::setPalette | ( | IlvPalette * | palette | ) |
Sets the palette used to create the graphic objects.
| palette | The palette to be set. |
| void IlvDefaultPointRenderer::setPattern | ( | IlvPattern * | pattern | ) |
Sets a pattern for the marker.
The pattern is used for the marker types that fill an area (IlvMarkerFilledSquare, IlvMarkerFilledCircle, IlvMarkerFilledDiamond, IlvMarkerFilledTriangle).
setPalette. | pattern | The pattern. |
| IlvMapsError IlvDefaultPointRenderer::setPattern | ( | const char * | fileName | ) |
Sets a pattern for the marker by specifying a file name.
The pattern is used for the marker types that fill an area (IlvMarkerFilledSquare, IlvMarkerFilledCircle, IlvMarkerFilledDiamond, IlvMarkerFilledTriangle).
| fileName | Name of the file containing the pattern. |
setPalette. MapsError::IllegalArgument() if the name supplied is not a valid bitmap file name. © Copyright 2014, Rogue Wave Software, Inc. All Rights Reserved.
