VisualAp

VisualAp is a visual framework for building application and systems based on visual components.

Overview

VisualAp can be used in order to perform audio processing, image processing, text and other process-driven emulation. VisualAp provides a visual framework based on lightweight components, called proclet. The user can create an application by selecting the components from a toolbox, configuring the parameters (via the Javabeans framework), and connecting the components together in order to set-up communication channels between the components. Please click here and read the user guide for more information.

This application has to be compiled and run with Java 8, later versions are currently not supported.

Build

The batch file build.bat can be used to build the project. It generates the classes and two jar files: visualap-setup.jar and visualap.jar
