Raster Transparency 3.0

The next plugin I picked up for updating to Qt6 was Raster Transparency.

Contrary to the Statist plugin, which was not only ported to Qt6 but also underwent refactoring and a UI update, this plugin received only minor changes focused on Qt6 compatibility. The main reason for this is that the QGIS API does not offer any new features that would benefit the Raster Transparency plugin.

While writing this post, I realized I have never written a word about this plugin on my blog. Let’s fix that!

Raster Transparency is a QGIS plugin designed to interactively define transparent pixel ranges for raster layers. While this can be done in the “Transparency” tab of the layer properties dialog, this plugin is more convenient. It integrates into the “Layer Styling” panel and allows you to adjust transparent pixel ranges using a dual-handle slider and/or spinboxes. The raster updates interactively as you move the handles or change spinboxes’ values, providing immediate visual feedback.

Check the plugin documentation for more details and installation instructions.
