Java Imaging task: create a laptop, ipad and iphone device mockup

Your tasks are:

- suggest us device images which look realistic (smartphone, tab, laptop, see below for one suggestion)

- take the suggested image and measure manually the screens pixel width and height along with the offset as a reference for your mockup (we name this measuring mockup-device-width and height)

- persist the image and the screensize and offset (where the device screen starts) and persist it beside of the image as json

- create manually (no programming) screenshots e.g. in the browser with identical pixels of the mockup-device-width and height

- create manually (no programming) screenshots of different sizes to the mockup-device-width and height

- create per device type one method with parameters Screenshot-File and scale-boolean in java to be able to add unscaled and scaled screenshots to the mockup with mockup-device-width and heights

- add the screenshots into the mockups (ensure the cam and speaker notch and e.g. round corners are properly considered) to make the full mockup to look realistic

- the scaling is very easy since you know of your suggested image the devices screen size you can take the screenshots width and height and you can scale it to it

As the content of the screen you can create screenshots of this page in different resolutions

- The images have to be saved in png, jpg and webp

- example for the device mockup: [login to view URL] in the proper orientation)


- works well on Windows and Linux

- your methods are executed by a bunch of unit tests to test different devices and different screens

- your test screenshots are part of src/test/resources folder

What is NOT needed:

- a UI (not required, implement a JUnit test to call your functions)

- any reporting framework (which is typically a form of a view only UI)

- a service architecture (like spring or JEE)

- persistency

What are our requirements?

- your code passes checkstyle, pmd and findbugs (we will share you a git repo with eclipse settings)

- JDK11

- maven

- create a model class representing the input of your function

- create a service class implementing the logic

- create a unit test, which tests the service class

- we do NOT need a UI, we only need the model + service method to access the logic via API or via JUnit

- if you need libs beside of selenium or jgrapht, apache commons are fine. Other libs NEED prior clearance

- the runtime is JRE (no JavaEE nor Spring-container)

- deliviery in our git


- if you do a good job on supporting our team, we are open to integrate you into regular work
