Project: QGIS
Version: 3.20
An option to trim the start and end of simple line symbols was added, allowing for the line rendering to trim off the first and last sections of a line at a user configured distance. It is useful for creating complex symbols where a line layer should not overlap marker symbol layers placed at the start or end positions of a line feature, such as with transport routes. The trim distance supports a range of units, including a percentage of the overall line length, and can also be configured as a data-defined property.
