A Spring web application for resizing images

Usage

JAVA_HOME=/path/to/java/java-15-openjdk ./mvnw spring-boot:run

API Usage

to resize a Base64 encoded image, make a POST call to /resize with base64 and scale as body param.

curl --request POST \
  --url https://java-img-resize.herokuapp.com/resize \
  --header 'content-type: application/json' \
  --data '{
	"scale": 0.1,
	"base64": ".... base64 string here ....."
}'

the scale param determines whether to scale up or down the image dimensions. scale<1 will reduce the size, and scale>1 will increase the size. scale must be greater than 0.

to resize an image available at a remote location:

curl --request POST \
  --url https://java-img-resize.herokuapp.com/resize \
  --header 'content-type: application/json' \
  --data '{
	"scale": 0.1,
	"url": "image url here"
}'
