QGIS 4 ready Active
Yes — DDM Line Direction supports QGIS 4 (declared max version 4.99.0).
Overlay and animate lines/polylines with per-field arrowhead styling.
About
Adds a live canvas overlay for line direction visualisation. Arrow density adapts with map scale: networks are sparse when zoomed out and more detailed when zoomed in. Direction follows vertex order, i.e. the original digitising direction of each line feature. Arrowheads can be styled based per field value: each styling rule matches a field value and sets its own fill, outline, opacity, size, density and animation speed, with a default style for the rest. Arrowheads can also be animated along the linework with customisable speed. Several line layers can be overlaid at once, each with its own styling rules and animation.
