Py Animate Hue

This script allows the user to create an animation from a still image by shifting hue, brightness, and contrast in a simple programatic way.

Project Structure

• animate.py: The main script for processing images.
• inbox/: Folder containing sample images for processing.
• presets.json: File containing predefined settings for image processing.

Demonstration

The following gif was generated with the "huego" preset which rotates hue 360 degrees over 30 frames:

The following mp4 was generated with the "huegolong" preset which rotates hue 360 degrees over 920 frames:

python-sample-c.mp4

Requirements

Ensure you have Python 3.x installed on your system. Dependencies are listed in requirements.txt, typically including:

• Pillow (PIL Fork) - The Python Imaging Library adds image processing capabilities.
• tqdm - A Fast, Extensible Progress Bar for Python.
• imageio - A Python library for reading and writing image data.

Installation

To install the required libraries, use the following command in your project's root directory:

pip install -r requirements.txt

Usage

Running the Script

To start the image processing, run the script from your command line:

python animate.py

User Interaction and Inputs

Once the script is running, it interacts with the user through the command line interface (CLI) to collect the following inputs:

1. Image Selection:

   • The script lists all images in the inbox folder.
   • You will be prompted to enter the number corresponding to the image you wish to process.

2. Using Presets:

   • If presets are available (defined in presets.json), you can choose to apply one.
   • The script will list available presets and ask if you wish to use one.
   • Selecting a preset applies predefined settings for hue, brightness, contrast, and number of frames.

3. Custom Settings:

   • If not using a preset, you can customize the following settings:
     • Hue: Define the start and end hue values (range -180 to 180). This changes the color tone of the image.
     • Brightness: Set the start and end brightness levels (range -100 to 100). This affects the lightness or darkness of the image.
     • Contrast: Adjust the start and end contrast values (range -100 to 100). This alters the difference between dark and light areas of the image.
     • Number of Frames: Determines the smoothness and length of the animation (higher number for smoother animation).

Understanding the Settings

• Hue Shift: Alters the color spectrum of the image, creating visually dynamic effects.
• Brightness Adjustment: Useful for creating a transition from dark to light or vice-versa.
• Contrast Modification: Enhances or reduces the sharpness and clarity of the image.
• Number of Frames: Affects the duration and fluidity of the resulting animation. A higher number results in a longer and smoother animation but increases processing time.

After these inputs, the script processes the selected image and saves the animated result in the outbox folder either as a gif, mp4, or both depending on user direction.

Features

• Adjust hue, brightness, and contrast of images.
• Generate animated image transitions in GIF and MP4 formats.
• Use preset configurations for consistent effects.
• Interactive CLI for selecting and processing images.

Configuration and Presets

• presets.json contains predefined settings.
• You can create custom presets or modify existing ones.

Preset Examples:

• huego: Cycle through the color spectrum in 30 frames (good for a gif)
• huegolong: Same as huego but for 920 frames. (better for a mp4)
• darktolight: Gradually increase brightness.
• contra: Enhance contrast over time.
• party: A combination of color and contrast changes for a party-like effect.
