CurvesWidget README

---

Description:

CurvesWidget is a PySide6 widget designed for level correction of images using a curve. It provides a sophisticated tool for adjusting color, brightness, and contrast by manipulating a curve representing the tonal range of the image. This widget is particularly useful for fine-tuning RGB images.

---

Features:

• Curve Adjustment: The CurvesWidget allows users to manipulate a curve representing brightness, red, blue, and green levels individually to achieve desired adjustments.

• Color Correction: Users can precisely adjust the color balance by modifying the RGB channels independently.

• Brightness and Contrast: The widget provides control over brightness and contrast by shaping the curve according to the desired tonal range.

Usage:

1. Installation:

   • Ensure you have PySide6 installed. If not, you can install it via pip:

     pip install PySide6 opencv-python scipy
     

2. Integration:

   • Import the CurvesWidget module into your project.

   from curves_widget import CurvesWidget

3. Initialization:

   • Create an instance of the CurvesWidget and add it to your GUI layout.

   curves_widget = LevelEditor()
   layout.addWidget(curves_widget)

4. Usage:

   • Use the mouse to manipulate the curve by dragging control points. Each point represents a specific tonal range, allowing precise adjustments to brightness, red, blue, and green levels.
   • Double-click anywhere on the curve to add more control points for finer adjustments.
