The StartOffset, EndOffset, and Repeat parameters in LineUsage (for the new symbolization) allow you to control where symbols are drawn on the linestring feature.
Certain combinations of these are not yet being correctly handled.
If Repeat is <=0 then you'll only get a symbol at the start and / or end. Some examples:
- StartOffset >= 0, EndOffset not specified:
- if Repeat > 0, first symbol position is at the specified offset, following by additional regularly-spaced positions
- if Repeat <= 0, get one symbol position at the specified offset (relative to the start of the curve)
- EndOffset >= 0, StartOffset not specified:
- if Repeat > 0, last symbol position ends at the specified offset, preceded by regularly-spaced positions
- if Repeat <= 0, get one symbol position at the specified offset (relative to the end of the curve)
- StartOffset >= 0, EndOffset >= 0:
- if Repeat > 0, first and last symbol positions are at the specified offsets, with in between positions distributed at approximately the specified interval
- if Repeat <= 0, only get a first and last symbol at the specified offsets
