+Halftone Effect App
+
+This application allows users to apply a halftone effect to an image using different shapes such as circles, squares, or triangles. The halftone effect is a technique that simulates continuous tone imagery through the use of dots, varying in size and spacing.
+Requirements
+To run this app, you need to have Python installed along with the following libraries:
+Gradio
+Pillow
+You can install these libraries using pip:
+pip install gradio Pillow
+Usage
+Upload an image using the interface.
+Select a shape type (circle, square, or triangle) from the dropdown menu.
+View the output image with the applied halftone effect.
+How it Works
+The halftone effect is achieved by:
+Converting the input image to grayscale.
+Creating a grid over the image with a specified spacing (default is 10 pixels).
+For each grid point, calculating the grayscale value (brightness) at that point.
+Determining the size of the shape based on the grayscale value: darker areas get larger shapes, lighter areas get smaller or no shapes.
+Drawing the selected shape (circle, square, or triangle) at each grid point with the calculated size.
+Parameters
+grid_spacing: Controls the density of shapes. Smaller values create denser patterns but may slow processing. Default is 10 pixels.
+max_size: Ensures shapes don't overlap too much. Adjust as needed for desired effect. Default is 8 pixels.
+Notes
+The app is built using Gradio, which provides a user-friendly web interface.
+For large images or small grid_spacing, processing may take longer. Adjust parameters for faster results.
+Future enhancements could include adjustable parameters via sliders, colored shapes, or additional shape types.
