This renderer translates a map feature whose geometry is an IlvMapPoint into an IlvMarker.
Library: ilvmaps
◆ IlvDefaultPointRenderer() [1/2]
| IlvDefaultPointRenderer::IlvDefaultPointRenderer |
( |
IlvDisplay * |
display | ) |
|
Initializes a new instance of the renderer.
- Parameters
-
| display | The display used to create the graphic objects. |
◆ IlvDefaultPointRenderer() [2/2]
Initializes a new instance of the renderer as a copy of another one.
- Parameters
-
| source | The object to be copied. |
◆ getForeground()
| IlvColor* IlvDefaultPointRenderer::getForeground |
( |
| ) |
const |
Returns the foreground color used to draw the marker.
- Returns
0 if no color is specified (in this case, the default display foreground color is used), or an 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.
◆ getLineWidth()
| IlUShort IlvDefaultPointRenderer::getLineWidth |
( |
| ) |
const |
Returns the line width.
- Returns
- The line width.
◆ getMarkerSize()
| IlUShort IlvDefaultPointRenderer::getMarkerSize |
( |
| ) |
const |
Returns the size of marker produced by this renderer.
- Returns
- The marker size.
◆ getMarkerType()
Returns the marker type.
- Returns
- The marker type.
◆ getPalette()
| IlvPalette* IlvDefaultPointRenderer::getPalette |
( |
| ) |
const |
Returns the palette used to create the graphic objects.
- Returns
- An
IlvPalette object 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.
- See also
IlvResource::lock().
◆ getPattern()
| IlvPattern* IlvDefaultPointRenderer::getPattern |
( |
| ) |
const |
Returns the pattern used for the marker.
- Returns
0 if no pattern is specified, or an IlvPattern 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.
◆ makeGraphic()
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.
- Parameters
-
| 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 0), 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). |
- Returns
- An
IlvGraphic or a null pointer if a severe error occurred.
Implements IlvFeatureRenderer.
◆ setForeground() [1/2]
| 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.
- Note
- This function is a convenience function that can be used instead of
setPalette().
- Parameters
-
| colorName | The name of the color. |
- Returns
IlvMapsError::NoError() or IlvMaps::IllegalArgument() if the color name cannot be translated into a color.
◆ setForeground() [2/2]
| 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.
- Note
- This function is a convenience function that can be used instead of
setPalette().
- Parameters
-
| color | The foreground color used to draw the marker. |
◆ setLineWidth()
| 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.
- Note
- This function is a convenience function that can be used instead of
setPalette().
- Parameters
-
| lineWidth | The new line width. |
◆ setMarkerSize()
| void IlvDefaultPointRenderer::setMarkerSize |
( |
IlUShort |
markerSize | ) |
|
Sets the size of the marker produced by this renderer.
- Parameters
-
| markerSize | The size of the marker. |
◆ setMarkerType()
| void IlvDefaultPointRenderer::setMarkerType |
( |
IlvMarkerType |
markerType | ) |
|
Sets the marker type used by this renderer.
- Parameters
-
| markerType | The marker type. |
◆ setPalette()
| void IlvDefaultPointRenderer::setPalette |
( |
IlvPalette * |
palette | ) |
|
Sets the palette used to create the graphic objects.
- Parameters
-
| palette | The palette to be set. |
◆ setPattern() [1/2]
| 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).
- Parameters
-
| fileName | Name of the file containing the pattern. |
- Note
- This function is a convenience function that can be used instead of
setPalette().
- Returns
MapsError::IllegalArgument() if the name supplied is not a valid bitmap file name.
◆ setPattern() [2/2]
| 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).
- Note
- function is a convenience function that can be used instead of
setPalette().
- Parameters
-
