Curve Text

Element	<CurveText>
Description	The geometry of the associated feature or dynamic graphic element (e.g.arc) is used as the reference curve for the text. The text follows the curve. The position of the text extent is defined using the offsets and placement information. Sub elements allow the text to include multiple styles and strings. The curve text object may contain a sequence of elements used to construct the text to be displayed. The sub elements are made up of one or more Style elements as defined under PointText.
Example	• The text is value of the `colourLabel` attribute • Text is fitted to the middle of the curve with no offset.The font is Arial with at 7 point and the colour is black.

Attributes
Name	Type	Description
xPlacement	Enumerated	Status: Optional. This attribute indicates how the text is fitted to the curve. Three values are available: • `Left` means the text is started at the start of the arc and follows the arc (going clockwise). • `Middle` means the text is centred on the middle of the curve. • `Right` means the right end of the text starts at the right end of the arc and follows the arc. The text will be reversed or flipped to keep the text readable so `Left` and `Right` are the sides of the text frame with respect to the Y-axis. Default is `Middle`.
yPlacement	Enumerated	Status: Optional. Available values: • `Baseline` is the imaginary line upon which a line of text rests. • `Bottom` (default) is the bottom edge of the text frame with respect to the positive Y-axis. • `Middle` is the middle of the text frame. • `Top` is the top edge of the text frame with respect to the positive Y-axis. If text is along a line and `keepUpright` is True, western bearing text will be reversed and the Y-offset direction flipped to keep the text readable so the `Top` and `Bottom` are with respect to the Y-axis.
xOffset	Floating Point	Status: Optional. This attribute shifts the `xPlacement` position along the curve. The units are mm. Default is 0.
yOffset	Floating Point	Status: Optional. Perpendicular offset from the tangent of the line. The units are mm at display scale. The curve text object may contain a sequence of elements used to construct the text to be displayed. The sub elements are made up of one or more Style elements as defined under PointText. Default is 0.
Style	String	A container of strings which will be represented using a style definition: • `font`: font or typeface name • `colour`: colour token • `size`: text size in points • `bold`: optional boolean set to `True` or `False` (default) • `italic`: optional boolean set to `True` or `False` (default) • `underline`: optional boolean set `True` or `False` (default)
