Pixel Coordinates Finder

Simple Flask app that allows finding pixel coordinates based on user-defined image dimension and corners through HTTP requests. This web server can handle normal FORM HTTP requests to http://localhost:5000/.

Usage

The easier way to run this web service is to run it through a Docker container. The web service is packed in a Docker container, which can be found here. In order to be able to pull and run a Docker container, you'll need Docker installed if you haven't already done so.

Commands

Pull Docker image:

docker pull xuxiaqing2011/pixels

Run in a container: port 5000 and detached mode(optional)

docker run -p 5000:5000 -d xuxiaqing2011/pixels

Send GET/POST requests:

• GET request

curl http://localhost:5000

• POST request

curl -d "r=3&c=3&x1=1&y1=1&x2=3&y2=3&x3=1&y3=3&x4=3&y4=1" -X POST http://127.0.0.1:5000 

Note: Content-Type: application/x-www-form-urlencoded

In addition, if you have previously run the container in detached mode, the web service then can be accesed through your browser. Navigate to http://localhost:5000 .

A GET request renders the form where image dimension and corner coordinates can be entered and submitted, so that a POST request can do the calculation and display the result.
