How to Convert SVS File to JPEG Images Using Python

 Converting SVS (SVS Slide Image) files to JPEG format can be effortlessly accomplished with Python using the openslide and PIL (Python Imaging Library) libraries. This approach allows for seamless reading of SVS files and efficient conversion to JPEG format.

Installation of Required Libraries

Firstly, ensure you have the necessary libraries installed by running the following command:

pip install openslide-python pillow

Python Script

Below is a Python script demonstrating how to convert SVS files to JPEG format:

from openslide import OpenSlide

from PIL import Image



def convert_svs_to_jpeg(input_file, output_file):

    slide = OpenSlide(input_file)

    # Select the desired level of the slide

    level = 0

    # Convert the slide image to RGB

    rgb_image = slide.read_region((0, 0), level, slide.level_dimensions[level])

    # Convert to PIL Image

    pil_image = rgb_image.convert("RGB")

    # Save as JPEG

    pil_image.save(output_file, "JPEG")



if __name__ == "__main__":

    input_file = "input.svs"  # Path to the input SVS file

    output_file = "output.jpg"  # Path to the output JPEG file

    convert_svs_to_jpeg(input_file, output_file)

Usage

To use the script, replace "input.svs" with the path to your SVS file and "output.jpg" with the desired output JPEG file path. The script will then read the SVS file, convert it to RGB format, and save it as a JPEG file.

Adjusting Parameters

You can adjust the level parameter based on your requirements, as SVS files often contain multiple levels of resolution for the image.

Following these steps, you can effortlessly convert SVS files to JPEG format using Python, facilitating seamless image processing tasks.
