Simple get size, and resize images using OpenCV

A simple code snippet to get size, and resize images using the Python OpenCV library. Python >= 3.6

Windows

Step 1 - Clone repository

git clone https://github.com/BehzadRp98/SizeResizeImages_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 srImages

3 - Activate virtual enviroment

srImagesEnv\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 srImages.py --input images\flower.jpg --output out.png --display_height 500 --display_width 500 --output_height 500 --output_width 500

All options:

python srImages.py --help
usage: srImages.py [-h] --input INPUT --output OUTPUT [--display_height DISPLAY_HEIGHT]
                       [--display_width DISPLAY_WIDTH] [--output_height OUTPUT_HEIGHT] [--output_width OUTPUT_WIDTH]
    
    Get Size and Resize 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
      --display_height DISPLAY_HEIGHT
                            [OPTIONAL] Display window height size
      --display_width DISPLAY_WIDTH
                            [OPTIONAL] Display window width size
      --output_height OUTPUT_HEIGHT
                            [OPTIONAL] Output image height
      --output_width OUTPUT_WIDTH
                            [OPTIONAL] Output image width

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 srImages

3 - Activate virtual enviroment

source ./srImages/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 srImages.py --input ./images/flower.jpg --output ./out.png --display_height 500 --display_width 500 --output_height 500 --output_width 500

All options:

python3 srImages.py --help
usage: srImages.py [-h] --input INPUT --output OUTPUT [--display_height DISPLAY_HEIGHT]
                   [--display_width DISPLAY_WIDTH] [--output_height OUTPUT_HEIGHT] [--output_width OUTPUT_WIDTH]

Get Size and Resize 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
  --display_height DISPLAY_HEIGHT
                        [OPTIONAL] Display window height size
  --display_width DISPLAY_WIDTH
                        [OPTIONAL] Display window width size
  --output_height OUTPUT_HEIGHT
                        [OPTIONAL] Output image height
  --output_width OUTPUT_WIDTH
                        [OPTIONAL] Output image width
