What's new?

New controls

● WorkspaceTree: Manages data nodes in the workspace.
● LayersTree: Manages layers in the map.
● Layer3DsTree: Manages layers in the scene.

Data module

● Improved Recordset accessing performance; new methods added for specific data types, to reduce the cost of boxing and unboxing when manipulating value types and to avoid the type conversion in encoding.

Mapping module

● Improved performance of avoiding text overlapping.
● Improved performance of displaying text in small sizes legibly.

Conversion module

● New function for getting the projection of img files.
● Improved functionality of importing imagery to multiband rasters.
● Fixed problems with importing wor to an existing workspace and with showing text in unexpected different font sizes in thematic mapping.
● Fixed error in getting wkt projection info defined by ESRI.
● Fixed problem of invalid encoding after importing imagery.

Layout module

● New fine-grained interfaces for MapLayoutControl and MapLayout to support development flexibility.
● New support for 12 layout element alignments, including left alignment, right alignment, etc.
● New support for spacing and aligning selected layout elements, e.g. making elements horizontal and/or vertical spacing equal.
● New support for making the selected layout elements same size, same width, or same size.
● Optimized layout refreshing to improve the performance of refreshing layouts with large-volume data.
● Easier-to-use layout legends.
● Improved visual effects for the layout ruler and scale bar.

Realspace module

● Enhanced 3D thematic map functionalities, including 3D ranges map and 3D label map, and new support for stretching in 3D ranges map.
● New support for displaying KML data in different levels, including point markers, lines, and polygons.
● New support for 3D scene realtime refreshing.
● Improved 3D browsing approach to increase the performance, especially in panning across 3D buildings.
● Improved terrain and imagery visualization performance by using new anti-shaking algorithms.
● Improved vector line and region display performance by using new algorithms.
● Improved performance in displaying fine textures smoothly and clearly.
● Fixed display error in vector polygon self-intersecting.
● Fixed problem of slow syncronized displaying of multiple 3D windows and failing to refresh.

Spatial Analysis

● Improved efficiency in spatial query using the contain method.
● Improvements made in overlay analysis preprocessing.
● Improved stability and efficiency in interpolation.
● Improvements made in creating flat buffer for closed curves.
● Improved performance in dealing with Thiessen polygons.

Network Analysis

● Optimized algorithm for finding optimal paths in network analysis, and new support for unified processing of turn tables, coordinate points, and nodes.

Topology module

● Optimized topology preprocessing mechanism to improve the performance.

Technology Documents

● New sample code and explanatory documentation for auxiliary controls.
