Short Description
Dropwizard Web service that exposes Sikuli fuzzy image matching API
Full Description

Sikuli Web

Exposing the Sikuli API as a web service.

This is a quick proof-of-concept for running Sikuli as a web service, so that
other testing frameworks like Selenium can use its image recognition functions.

Example

Start the Dropwizard service:

gradle run

Create a script to POST a request to the /find resource:


import base64, json, os, sys, urllib2

ROOT = os.path.abspath(os.path.dirname(__file__))
IMAGE_DIR = '../src/test/resources/com/glonk/sikuliweb'
BASE_URL = 'http://localhost:8080'
OPENER = urllib2.build_opener()
MIME_JSON = {'Content-Type': 'application/json'}

def read_image(name):
    'Read an image from disk, returning it as base64'
    path = os.path.join(ROOT, IMAGE_DIR, name)
    return base64.b64encode(open(path, 'rb').read())

def find(**params):
    'Find target image in screen'
    data = json.dumps(params)
    url = BASE_URL + '/find'
    req = urllib2.Request(url, data, headers=MIME_JSON)
    res = OPENER.open(req)
    return json.loads(res.read())

def main():
    res = find(
        screen = read_image('test-field.png'),
        target = read_image('boing-ball.png'),
        minScore = 0.9,
        limit = 5
        )
    print json.dumps(res, indent=2)

if __name__ == '__main__':
    main()

Running the above script produces this JSON output, indicating the positions
within screen image where the target image matched, and the score for each
match.
