Transmittance Layer ctl QGIS 4 compatibility
QGIS 4 ready Active
Yes — Transmittance Layer ctl supports QGIS 4 (declared max version 4.99.0).
Group layers and control their opacity, order, and labeling as a single blended layer.
About
Tag any QGIS layer group as a "Transmittance Group" to open an interactive 2D control panel. The canvas plots each layer as a draggable dot — X axis controls stacking order, Y axis controls opacity. Drag a dot to adjust both at once. Click a dot to toggle its visibility. Key features: - Real-time opacity and order editing with immediate map feedback - Label control: a △ indicator selects which layer displays its QGIS label - Exclusive Control mode: click any dot to show only that layer and its label; cycle through layers with arrow keys - Opacity clamping: define an upper/lower opacity range applied across all layers - Presets (×4): save and restore full panel states, including order, opacity, clamping, and exclusive control settings Designed for workflows that involve comparing multiple overlapping layers — such as elevation models, orthophotos, and feature layers — where visual blending and quick layer switching matter.
