Advanced callout/multiple text element annotation parameters (Aviation)
The parameters listed here are used to create advanced annotation. The parameters listed include subparameters that are needed inside the XML tag to format the custom annotation. The subparameters are in the MultipleTextElement tag, which is a container for all of the properties for the advanced callout elements.
The subparameters can be divided into the following categories and are explained in greater detail below.
- Display properties—These tags manage the display of the advanced callout and include the text background color, background color, callout snapping and tolerance, shadow on the callout box, and margins.
- Text placement—These tags manage the placement of the text within the callout.
- Content—These tags contain the callout content for each element.
Display properties tags
The display properties manage the appearance of the callout container. This includes properties such as the text background color, the background color for the callout, display properties within the chart, the shadow on the callout, and the margins. The diagram below shows the tags and their specific settings. The tags are the green boxes, while the attributes are the yellow ones. Settings for the individual attributes are in blue boxes.
The sections below describe the individual tags and their attributes.
