![]() Working together, these two classes make things happen! The DictionaryRenderer class is responsible for the actual visualization of the symbols on the map from the symbol dictionary we just talked about. The companion class to our SymbolDictionary is the DictionaryRenderer. Well, not quite yet, but the long-term plan is to provide this capability, as well as the capability to modify and use existing symbol dictionaries. ![]() Other military specs are coming in the Final release, scheduled for November, including MIL-STD-2525B and C, and APP-6(B). You may be asking yourself, “ I wonder if I can create one of these from scratch in Pro, then use it straight away to display my own custom symbology.“. It only contains the specification for MIL-STD-2525D. In the current Beta releases for Java and Qt, we provide a pre-built stylx file for you in the SDK. These attributes are used to select different symbol primitives in the style file that are assembled to create a unique symbol. For example, the MIL-STD-2525D specification looks for attributes named “identity”, “symbolset”, “symbolentity”, and “modifier1″, among many others. Each specification depends on attribute names that define the symbology and text of each feature. The SymbolDictionary constructor takes a given specification, such as “mil2525d”. The stylx file is in the form of a binary SQLite database, created from ArcGIS Pro. New symbols from the input attributes are assembled based on the attributes of the Feature or Graphic and prepared for rendering. The stylx file contains the symbol primitives for a given symbology specification (such as MIL-STD-2525D), as well as a rule engine that parses input fields from the dictionary. Let’s begin by looking at the SymbolDictionary class. A SymbolDictionary makes use of what is known as a *.stylx file. This is different from pre-Quartz versions of Runtime, where military symbology could only be displayed as Graphics. Military symbology can be used for rendering points, lines and polygons in either a GraphicOverlay or a FeatureLayer. Heads up! These concepts now apply to both Graphics and Features. The purpose of this blog is to introduce how it all works and to help you get started working with military symbology.įor those of you that used military symbology in pre-Quartz versions of ArcGIS Runtime. ![]() We know that many of you have been waiting anxiously for Quartz’s support for displaying your data using military symbology. So far, we have received a wealth of excellent feedback and great catches, so please keep them coming. We invite you to continue collaborating with us. If you are an ArcGIS Runtime SDK developer, we hope you have had some time to dive in and investigate the new Quartz features and provide feedback to the development teams. A few weeks ago, Esri released Quartz beta’s for all of the ArcGIS Runtime SDKs. ![]()
