Must be an integer ranging from 0 to 100 :

• 0 = no compression.
• 1 = worst quality, smaller file.
• 100 = best quality, biggest file.
• default value is 85

This only applies to JPG/JPEG and WEBP image files.

Usage

You can call the API to resize image with post method. Currently it only accept remote image.

Get cropped image by GET method:

You can just use the this url to crop the image. This method will return an cropped image directly, not JSON result.

https://resize.sardo.work/?imageUrl={image_url}&width={image_width}&height={image_height}&quality={image_quality}

Get cropped image by POST method:

fetch('https://apiserver.com', {
  body:JSON.stringify({
    width: 500,
    height: 300,
    quality: 50,
    imageUrl: 'http://example.com/image.png',
  }),
  headers: {
    'content-type': 'application/json',
  },
  method: 'POST',
})
.then(response => response.json())
.then((result) =>{
  console.log(result);
});

If everything is OK, it will return a JSON which contain status and cropped image data (Data url of resized image):

{ status: 'Success',
  filename: 'image-filename.jpg',
  cropped_image_data:
   '/9j/4AAQSkZJRgABAQAAAQABAAD//gA7Q1JFQVRPUjogZ2QtanBlZyB2MS4wICh1c2luZyBJSkcgSlBFRyB2OTApLCBxdWFsaXR5ID0gODUK/9sAQwAFAwQEBAMFBAQEBQUFBgcMCAcHBwcPCwsJDBEPEhIRDxERExYcFxMUGhURERghGBodHR8fHxMXIiQiHiQcHh8e/9sAQwEFBQUHBgcOCAgOHhQRFB4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4eHh4e/8IAEQgBLAHWAwEiAAIRAQMRAf/EABwAAAEFAQEBAAAAAAAAAAAAAAIAAQQFBgMHCP/EABkBAQEBAQEBAAAAAAAAAAAAAAABAgMEB...' }

The API will not keep your image.

Otherwise it will return a json which contain error message. For example:

{ status: 'Failed',
  error_message: 'Please provide the url of image.'}

Frontend Test

You can test the api function without browser, there are a pre-ready script at frontend-test folder. It requires Node.js (Recommanded to use v10.x.x Version) to run.

Before use the script, install the dependencies by npm, then copy the config file:

cd frontend-test
npm install
cp config.example.json config.json

Edit the config file:

{
  "serverUrl": "Your api server url",
  "imageUrl": "Image for testing",
}

Then you can run it now.

node upload.js
