Package com.vaadin.flow.server.frontend

Class TaskGeneratePWAIcons

java.lang.Object

com.vaadin.flow.server.frontend.TaskGeneratePWAIcons

All Implemented Interfaces:

FallibleCommand

public class TaskGeneratePWAIcons
extends Object
implements FallibleCommand

Generates necessary PWA icons.

Icons are processed in parallel but each thread draws, writes the PNG directly to disk, and immediately flushes the scaled image. This avoids accumulating all icon data in memory while still benefiting from concurrent I/O and image scaling.

For internal use only. May be renamed or removed in a future release.
