Class LayerSettingGrid


  • public class LayerSettingGrid
extends LayerSetting
    Rhithers. Decision Rhitherges Rhithers. Rhitherite Rhithers. Rhitherite Rhitherd Rhithers. Rhither Rh.

    This class is used to set the display style of the raster layer, to get and set the special values of the raster layer, the color of the special value, and whether the special value is transparent. Grid layer corresponds to normal layer. It is style setting instance can be acquired from Layer.getAdditionalSetting(). You can also create a new object and set through the Layer.setAdditionalSetting(LayerSetting) method. After modifying the layer display, you need to call the methodMap.refresh()to refresh the map. Raster data structure, also known as the grid structure, is a two-dimensional matrix to express spatial data or the distribution of data organization. Raster data is actually a cell array, Each cell represents specific geometric bounds and property of each cell represents the value of a specific geographic feature, such as elevation, aspect, etc. The color of the cell in the map represents the value of it. Display colors of cells will be the same if they have the same values. In addition, in SuperMap, usually with -9999 denote the meaningless data of the pixel, that is, no value.

      • LayerSettingGrid

        public LayerSettingGrid()
        Initializes a new instance of this LayerSettingGrid class.

      • LayerSettingGrid

        public LayerSettingGrid(LayerSettingGrid layerSettingGrid)
        Constructor. Constructs a new instance according to the specified LayerSettingGrid object.
        Parameters:
        layerSettingGrid - Specifies the LayerSettingGrid object

    • Method Detail

      • getSpecialValueColor

        public Color getSpecialValueColor()
        Gets color corresponding to the special value of the grid layer.
        Returns:
        ColorClass, returns the corresponding color of the raster layer special value If the object is a new one, returns null.

      • setSpecialValueColor

        public void setSpecialValueColor(Color color)
        Sets color corresponding to the special value of the grid layer.

        When the specified special value is within the range displayed by the layer throughsetSpecialValue(double), and the value is opaque, the value will display the specified color.

        setSpecialValueTransparent(boolean)can be used to set whether the special value is to be displayed transparently.

        Parameters:
        color - Need to set the color

      • getSpecialValue

        public double getSpecialValue()
        Gst the special value of the grid layer.
        Returns:
        double type, returns the special value currently specified by the raster layer; the default value is -9999 (no value)

      • setSpecialValue

        public void setSpecialValue(double value)
        Sets the special value of the grid layer. The special value is actually the attribute value of the cell, you can specify cells with attributes.
        Parameters:
        value - double type, need to set the special value

      • isSpecialValueTransparent

        public boolean isSpecialValueTransparent()
        Gets whether the special value for the grid layer will display in transparent.
        Returns:
        boolean type, return to the current transparent display; default opaque, that is, return false

      • setSpecialValueTransparent

        public void setSpecialValueTransparent(boolean specialValueTransparent)
        Sets whether cells corresponding to the specified special value will display in transparent or not.
        Parameters:
        specialValueTransparent - boolean type, indicating whether the transparent display. When set to true, the cells corresponding to the special value will transparently display and the color set by setSpecialValueColor(Color) will not take effect.

      • getOpaqueRate

        public int getOpaqueRate()
        Gets the opacity of the Grid layer which ranges from 0 to 100, and 0 means the layer is transparent, while 100 means the layer is opaque. It works on a raster layer only
        Returns:
        Gets the opacity of the Grid layer

      • setOpaqueRate

        public void setOpaqueRate(int opaqueRate)
        Sets the opacity of the Grid layer which ranges from 0 to 100, and 0 means the layer is transparent, while 100 means the layer is opaque. It works on a raster layer only
