opencv-table-plotter

opencv-table-plotter is a simple Python library designed to overlay tables on images or frames using OpenCV. This library helps in drawing and customizing tables, including features like background color, opacity, title, and more.

Features

• Draw tables on images or video frames using OpenCV.
• Customize the number of rows and columns.
• Set table and cell dimensions.
• Add titles to the tables.
• Adjust font, colors, and opacity.

Installation

You can install the opencv-table-plotter library using pip:

pip install opencv-table-plotter

Usage

Here is a basic example of how to use opencv-table-plotter:

import cv2
import numpy as np
from opencv_table_plotter import plot_table

# Create a blank image
frame = np.ones((600, 1600, 3), dtype=np.uint8) * 255

# Data to be displayed in the table
cell_data = ["Cell 1", "Cell 2", "Cell 3", "Cell 4"]

# Draw table on the image
plot_table(
    frame,
    cell_data,
    num_rows=2,
    num_columns=2,
    title="Sample Table",
    col_width=400,
    row_height=60,
    font=cv2.FONT_HERSHEY_SIMPLEX,
    font_size=0.7,
    font_color=(0, 0, 0),
    border_color=(0, 0, 0),
    line_thickness=2,
    background_color=(200, 200, 200),
    opacity=0.5,
    start_x=100,
    start_y=20
)

# Display the image
cv2.imshow('Table', frame)
cv2.waitKey(0)
cv2.destroyAllWindows()

Function Parameters

plot_table

• frame: The image or video frame on which the table will be drawn.
• cell_data: List of strings to be displayed in the table cells.
• num_rows: Number of rows in the table (default: 2).
• num_columns: Number of columns in the table (default: 2).
• title: Title of the table (default: "").
• col_width: Width of each column (default: 400).
• row_height: Height of each row (default: 60).
• font: Font type for the text (default: cv2.FONT_HERSHEY_SIMPLEX).
• font_size: Font size for the text (default: 0.7).
• font_color: Font color in BGR (default: (0, 0, 0)).
• border_color: Border color of the table in BGR (default: (0, 0, 0)).
• line_thickness: Thickness of the table lines (default: 2).
• background_color: Background color of the table in BGR (default: (200, 200, 200)).
• opacity: Opacity of the background color (default: 0.5).
• start_x: Starting x-coordinate of the table (default: 1100).
