🚀 Widget Features

• ✅ Minimalist Interactive Design
• 🖌️ Scroll through label classes / Adjust pen size with the mouse wheel
• 🎨 Supports segmentation masks (.png) and bounding boxes (.txt)
• 🧠 Dynamic label color generation (HSV-based)
• 💬 Floating labels showing hovered and selected classes
• 💾 Auto-save and manual save (Ctrl+S)
• 🧽 Flood-fill segmentation with a postprocessing stage of binary hole filling
• 🚫 Right-click erase mode and double-click to clear all

🚀 CLI Features

• ✅ Minimalist Design
• 🎨 Navigate through images using A and D.

📦 Installation

Option 1: Install via pip

pip install tadqeeq

Option 2: Run from source

git clone https://github.com/orbits-it/tadqeeq.git
cd tadqeeq
pip install -r requirements.txt

---

🛠️ Usage

Import in your code:

from tadqeeq import ImageAnnotator

Run CLI tool from command line (if installed via pip):

tadqeeq [--verbose|--autosave|--use_bounding_boxes]* <images_directory_path> <annotations_directory_path> <class_names_filepath>

Notes: 1. Use A and D to navigate through images. 2. If "--use_bounding_boxes" is included, the annotation files in <images_directory_path> are: a) PNG for segmentation masks with class-labeled pixels on a white background. b) txt for YOLO-style bounding boxes formatted as: label_index x_offset y_offset width height. 3. <class_names_filepath> is a txt file containing a list of a class names used in annotating.
