Spline Color Adjustment Tool

This project is a Java Maven application built using NetBeans IDE and Swing that allows users to adjust the colors of an image through a cubic interpolated spline. The application provides fine control over the RGB and Alpha channels, enabling creative and precise image adjustments.

Features

• Color Channel Adjustment: Adjust individual color channels (Red, Green, Blue, and Alpha) using spline curves to achieve precise color corrections or artistic effects.
• Image Preview: Preview the adjusted image in the interface before saving.
• User-Friendly Controls: Drag, click or delete control points on spline curves to define custom transformations for each channel.

How to Use

1. Execute the .jar file located in the /target folder: SplineAdjust.jar.

2. Load an Image:

   • Drag and drop an image into the interface.

3. Adjust Colors:

   • Modify the spline curves for the chosen channel or all at once (Red, Green, Blue, Alpha) by dragging control points.

4. Save the Image:

   • Once satisfied with the adjustments, click the "Save" button.
   • The adjusted image will be saved in the same folder as the original with the name: originalname_ColorAdjusted[type].png.
