This renderer translates a map feature whose geometry is an IlvMapRaster
into an IlvZoomableIcon
whose colors indicate the value of the raster.

This renderer translates a map feature whose geometry is an IlvMapRaster
into an IlvZoomableIcon
whose colors indicate the value of the raster.
The translation from raster values to colors is performed by an IlvMapColorModel
. Library: ilvmaps
IlvDefaultRasterRenderer::IlvDefaultRasterRenderer | ( | IlvDisplay * | display, |
IlvMapColorModel * | colorModel, | ||
IlBoolean | ownerOfModel | ||
) |
Creates an instance of a renderer to render raster geometries.
display | The display for which graphics are rendered. |
colorModel | The colormodel used to translate raster values into colors. |
ownerOfModel | If IlTrue , the new owner of the colormodel is the renderer. The IlvDefaultRasterRenderer instance will delete the colorModel in its destructor. |
IlvDefaultRasterRenderer::IlvDefaultRasterRenderer | ( | const IlvDefaultRasterRenderer & | source | ) |
Creates a new renderer, copying the specified renderer.
source | The object to be copied. |
|
static |
The error returned when bitmaps cannot be created.
|
virtual |
Translates an IlvMapFeature
into a graphic object.
feature | The map feature to be translated. |
targetMapInfo | The target map info. |
status | Set to an error code if the renderer cannot process the map feature (often because the renderer does not support the feature geometry, but it can also indicate that a projection error occurred). |
IlvGraphic
object or a null pointer if a severe error occurred. Implements IlvFeatureRenderer.
