layerremoved

LayerRemoved is a term used in software that manages layered content to denote the removal of a layer from a project. It can refer to an explicit user action, such as deleting a layer in an editor, or to an internal event triggered when a layer is pruned from the data model. The exact behavior depends on the application, but common consequences include the removal of the layer's pixels, masks, adjustment layers, and any effects applied to it, as well as updates to the layer stack order.

In image editing programs, deleting a layer typically preserves other layers and may offer an option to merge the deleted layer with the one below or to discard it entirely. Many tools record the action for undo and redo history, allowing reversal.

In software development and APIs, LayerRemoved can be defined as an event or callback that fires after a layer is removed. Listeners can refresh the user interface, recalibrate composites, or free resources associated with the layer. In data structures that model layered content, removing a layer may require reindexing, updating references to neighboring layers, and adjusting the z-order.

Across domains such as vector graphics, CAD, or geographic information systems, the concept is analogous: a layer representing a data set or visual element is detached from the project, with potential impacts on rendering, visibility, and data relationships.
