bool(false)
A: Please check the raster/image dataset coordinate system. It requires all raster datasets or image datasets to have the same coordinate system.
03 Jul,2019 iDesktopA: The label expression that implements this effect in the UDB datasource is: “AREA”||” km#+2”. And you need to check the display upper and lower marks.
03 Jul,2019 iDesktopA: The text layer is different from the point, line, and region layers. The style is stored in the text object, so you need to perform two steps before modifying the text style: 1. Set the text layer editable; 2. Select the text object to be modified the style. You can either select one or select all the text objects, and then click the corresponding button in the text style group.
03 Jul,2019 iDesktopA: This effect can be achieved by setting the offset parameter of the advanced Settings in a UniqueTheme.
03 Jul,2019 iDesktopA: When you use the SymbolMarker.FromGeometry () method, the imported Rectangle2D parameter determines the symbol location. If the symbolBounds is set as the range of the whole symbol, then the geometry object scope (Bounds) will control the geometry objects position and scaling relation in the symbol. If you need to set the geometry object to fill the whole symbol, the symbolBounds can input the Bounds of geometry object.
03 Jul,2019 iDesktopA: The steps are as follows: 1. Please use the Map.ToXML method to get the map XML string; 2. Then use the Maps.Add method to add the map to the Maps. Notes: 1. XML string includes all map configuration information (map name, transparent , properties, layers, thematic map and so on). 2. Since the map depends on the workspace, you need to save the workspace before you exit the program.
03 Jul,2019 iDesktopA: Make the 3D shading map for the existing DEM data. And the vector data is overlaid with a certain degree of transparency.
03 Jul,2019 iDesktopA: Set the tracking layer to use antialiasing through the TrackingLayer.IsAntiali as property. After it set to antialiasing, you can remove the serrated to make t he display more beautiful.
03 Jul,2019 iDesktopA: You can modify the frequency in the water surface symbols to make the water wavier.
03 Jul,2019 iDesktopA: This is because the printed paper is less than the size of the layout paper. Solution: when printing, set the paper size and layout size the same at the page setting.
03 Jul,2019 iDesktopA: 1. First, according to the Layer3D.Type attribute, determine whether the Layer3DType is a Dataset Type. For example, the layer of Map and KML Type has no corresponding dataset; 2. If the 3D layer is the Dataset type, convert the Layer3D to the Layer3DDataset type; 3. Finally, get the dataset corresponding to the layer through Layer3DDataset.Dataset.
03 Jul,2019 iDesktopA:1. Clip the data. Use the map clipping function, and you can use the vector region object of the study area outlined to clip it. 2. Set the image data to the mask object. Use the display scope attribute of the image dataset property, and use the vector region of the study area as the display range.
03 Jul,2019 iDesktopA: Dataset encoding can reduce the size of the dataset itself. When the data is stored on the server side, the reduction of dataset size can reduce the transmission time between the server and the client.
03 Jul,2019 iDesktopA: Because it will generate a new workspace when you generated the entire scene caches. The textures path is relative to the workspace. So copy the original textures to the relative path of the workspace generated by the entire scene cache.
03 Jul,2019 iDesktopA: When you set the symbol to be scaled with (Layer.IsSymbolScalable = true), you need also set the Layer.SymbolScale property, namely, the symbol natural scale. This property specifies the map display scale corresponding to the symbol size when the map is scaled.
03 Jul,2019 iDesktopA: If the Boolean field name is A, the SQL statement with the field value of True is A= 1; the SQL statement with the field value of False is A=0.
03 Jul,2019 iDesktopA: In topology processing, you can merge multiple points closer to each other into one node by merging adjacent endpoints.
03 Jul,2019 iDesktopA: Here you need to rerender the selection set for the current KML layer, namely, call the layer3DKml.Selection.UpdateData() method.
03 Jul,2019 iDesktopA: Resample. The vector dataset resample: DatasetVector.Resample method The region object resample: Geometrist.Resample metod(Geometry, ResampleType, Double).
03 Jul,2019 iDesktopA: Because you used the System fonts. Please check whether the text font is the system font. If so, please change it to other fonts, such as: Song. The non-system font supports scaling by the layout.
