# Busbud Coding Challenge
## Requirements
Design an application which concurrently processes a series of images
with the following treatments:
### Scaling
Images must be scaled to 1500px on the x-axis.
### Blurring
A Gaussian blur with a radius of 6px.
### Cropping
Each scaled and blurred image must produce 3 cropped images 300px tall:
one cropped from the top, one from the bottom, and one from the center.
### Saving
The resulting images must be saved into the images folder following the type
of crop performed. So rome.jpeg would result three images:
```
rome-bottom.jpeg
rome-vmiddle.jpeg
rome-top.jpeg
```
This challenge isn't intended to be a measure of your ability to manipulate
images. The basic functions have been provided for you, and it's up to you
as to how to best use them in parallel.
### Non-functional
- Must accept a tuple whose first element is a unique name for the image,
and a file-like object as input. An example iterator `images` is provided.
- Must be written in Python 2.7 following PEP8.
- Must process images in parallel. How you organize this is entirely up to you.
Your solution will be benchmarked.
- Must use comments wisely. Communicate why something behaves the way it does
rather than what. It should be clear what the code does from reading it.
### Bonus Round
Extra points will be given for:
- Utilizing all CPU cores.
- Additionally scaling along the y axis and cropping along the x.
## Getting Started
Begin by forking this repo, cloning your fork, and installing its
dependencies.
### Setting up the Virtualenv
```
$ virtualenv -p python2.7 coding-challenge-backend-d
$ source coding-challenge-backend-d/bin/activate
$ cd coding-challenge-backend-d
$ git clone [email protected]:busbud/coding-challenge-d.git src
$ cd src
$ python setup.py develop
```
### Pillow
Image manipulation should be handled with the setuptools-friendly
fork of PIL, Pillow. Documentation is available in the [references](#references) section.
