Detailed Description
Note: You cannot declare or create a component of this type in QML code.
Symbols describe how graphics and features look on a map. Different symbols are used with different geometry types. Marker symbols are used to display those graphics and features that are based on point or multipoint geometries. Subtypes of this type represent specific types of marker symbols.
There are two types of offsets that may be specified.
- The offset of the visible symbol from the symbol's point geometry.
- The offset of a callout's leader line from the symbol's point geometry.
For each offset, you can specify an x-offset and a y-offset in device independent pixels (DIPs) using a Cartesian coordinate system for example, specifying an callout x-offset of -5.0 will offset the callout's leader left along the x-axis by five points.
Consider a PictureMarkerSymbol using the image of a pushpin. By default, the center of the image will be used as the anchor to center the image at the map location. However, if you wanted the needle of the pushpin to end at the map location, you would need to offset the image appropriately to make the needle's end coincide with the map location.

Property Documentation
The rotation angle (in degrees) of the symbol.
A positive rotation will turn the symbol in a counter-clockwise direction
Note: If the angle was set via JSON, it will be inverted (e.g. an angle of 20 will become -20).
Whether the symbol should rotate with the map or stay at the same angle with regards to the screen.
Default is Enums.SymbolAngleAlignmentMap. Only supported for GraphicsOverlay using Enums.GraphicsRenderingModeDynamic.
See also Enums.SymbolAngleAlignment and Enums.GraphicsRenderingMode.
The x-offset position for a callout's leader in relation to the symbol in device independent pixels (DIPs).
The y-offset position for a callout's leader in relation to the symbol in device independent pixels (DIPs).
The x-offset position for the symbol in relation to the graphic or feature's point geometry in device independent pixels (DIPs).
The y-offset position for the symbol in relation to the graphic or feature's point geometry in device independent pixels (DIPs).
