Simple read/write images using OpenCV

A simple code snippet to read, and write images using the Python OpenCV library. Python >= 3.6

Windows

Step 1 - Clone repository

git clone https://github.com/BehzadRp98/ReadWriteImage_Python_Component.git

Step 2 - Optional step

It is recommended that a virtual environment be enabled to install and test the code snippet.

1 - Install python virtual enviroment

python -m pip install virtualenv

2 - Create a virtual enviroment

python -m venv rwImages

3 - Activate virtual enviroment

rwImagesEnv\Scripts\activate

Step 3 - Install requirements

python -m pip install -r requirements.txt

Step 4 - Quick start

To test the repository quickly there is a flower photo in "images" folder:

python rwImages.py --input images\flower.jpg --output out.png

All options:

python rwImages.py --help
usage: rwImages.py [-h] --input INPUT --output OUTPUT

Read and write images

optional arguments:
  -h, --help       show this help message and exit
  --input INPUT    [REQUIRED] Source image path
  --output OUTPUT  [REQUIRED] Destination image path like: output.jpg

Unbutu

Step 1 - Clone repository

git clone https://github.com/BehzadRp98/ReadWriteImage_Python_Component.git

Step 2 - Optional step

It is recommended that a virtual environment be enabled to install and test the code snippet

1- Install python virtual enviroment

python3 -m pip install virtualenv

2 - Create a virtual enviroment

python3 -m venv rwImages

3 - Activate virtual enviroment

source ./rwImages/bin/activate

NOTE: If virtual enviroment activated use "python" instead of "python3"

Step 3 - Install requirements

python3 -m pip install -r requirements.txt

Step 4 - Quick start

To test the repository quickly there is a flower photo in "images" folder:

python3 rwImages.py --input ./images/flower.jpg --output ./out.png

All options:

python3 rwImages.py --help
usage: rwImages.py [-h] --input INPUT --output OUTPUT

Read and write images

optional arguments:
  -h, --help       show this help message and exit
  --input INPUT    [REQUIRED] Source image path
  --output OUTPUT  [REQUIRED] Destination image path like: output.jpg

Raspberry Pi 4

Step 1 - Clone repository
