======Project: VISUALIZATION - FUN WITH FLAGS (fwf0)======

=====Objective=====
To create a program that generates a representation of a flag of a certain level of design complexity.

=====Reading=====
Please be sure to familiarize yourself with the following content in "[[https://publications.gbdirect.co.uk//c_book/|the C book]]":

  * [[https://publications.gbdirect.co.uk//c_book/preface/|Preface]]
  * [[https://publications.gbdirect.co.uk//c_book/chapter1/|Chapter 1]]
  * [[https://publications.gbdirect.co.uk//c_book/chapter2/|Chapter 2]]

=====Background=====
For this project, you will be using a graphics design library to render an image of a flag.

While you are not restricted to officially recognized country flags, they do offer a great starting point:

  * https://www.countries-ofthe-world.com/flags-of-the-world.html

If there is some fictional country, other state/county/canton, or organization symbol you would like to implement instead, you are welcome to (so long as they conform to the difficulty levels specified below).

Difficulties are defined as follows:

====Easy====
An easy-level flag has the following criteria:

  * Solid colours, often in bands
  * Examples: France, Mali, Belgium

====Intermediate====
Intermediate-level flags are classified as follows:

  * At least three distinct colours used on the flag.
  * More than one geometric shape utilized on the flag (ie not JUST rectangles/squares).
  * Examples: Bahamas, Laos, Maldives, Niger

====Medium====
  * Three or more colours
  * Contains three different geometric shapes (oval(s), triangle(s), star(s), rectangle(s))
  * Examples: Malaysia, Algeria, Antigua and Barbuda

====Complex====
  * Increased level of detail above that of medium
  * Creation utilizes loops
  * Examples: USA, Croatia, Philippines

=====Program=====
It is your task to write a program that generates a flag image, in the current directory as your source code and binary, named and accessible as **fwf0.png**

The flag is to be an intermediate-level flag (although you might want to start with an easy-level flag to gain some practice with the library and things like coordinates); opting to do and submit something of higher difficulty may earn you some bonus points.

====On your pi====
Develop and test this program on your pi. Only when done, verify that it compiles on lab46.

To utilize the needed functionality for this project, you will need to ensure you have the following packages installed:

  * build-essential (hopefully you took care of this in ntr0)
  * libgd-dev
  * libgd-tools
  * libgd3

=====Specifications=====
Your program should:

  * have valid, descriptive variable names of length //no shorter than// 4 symbols
  * have consistent, well-defined indentation (no less than 4 spaces per level of indentation)
    * all code within the same scope aligned to its indentation level
  * have proximal comments explaining your rationale and what is going on, throughout your code
  * perform the intended operation, outputting the correct/accurate information in indicated format
  * at the end of your main() function, use a single return statement to conclude your code, return a 0 indicating successful operation

=====Grabbing project resources=====
I have prepared a **grabit** for resources related to this project. To obtain:

<cli>
lab46:~/src/cprog$ grabit cprog fwf0
make: Entering directory '/var/public/SEMESTER/cprog/fwf0'
'/var/public/SEMESTER/cprog/fwf0/Makefile' -> '/home/user/src/cprog/fwf0/Makefile'
'/var/public/SEMESTER/cprog/fwf0/fwf0.c' -> '/home/user/src/cprog/fwf0/fwf0.c'
make: Leaving directory '/var/public/SEMESTER/cprog/fwf0'
lab46:~/src/cprog$ 
</cli>

At which point you can change into the newly created and populated **fwf0** directory.

=====Compiling=====
Since the grabit brought in a Makefile, you can compile your code simply by typing: **make**

Any compiler errors will go into a text file called **errors**

To do a full cleaning, run: **make clean** then **make** (or **make debug**)

If you'd like to see compiler messages as you compile, run: **make debug**

When done and ready to submit, on lab46: **make submit**

=====How to view the picture=====
Depending on your computing setup, choose the most practical means of viewing your program's image output:

====Raspberry Pi desktop====
You've got a monitor and keyboard hooked up to your pi that you are using (preferred method for class).

Open a file browser, web browser, or image viewer and navigate to/open up your **fwf0.png** image in your **~/src/desig/fwf0/** directory.

Rinse and repeat as you go through revisions.

====Raspberry Pi command-line via SSH/MOSH====
You don't have a monitor, so you are logging into your pi remotely (doable, and good intra-system practice)

Once your **Makefile** and **fwf0.c** file are added to your repository, **commit** and **push**.

On lab46, **pull** and **update**.

Compile:

<cli>
lab46:~/src/desig/fwf0$ make
</cli>

and run your program:

<cli>
lab46:~/src/desig/fwf0$ ./fwf0
</cli>

... which will produce an image (**fwf0.png**); You want to put this in your web space (with the proper permissions set), so you can view it in a web browser:

<cli>
lab46:~/src/desig/fwf0$ mv fwf0.png ~/public_html/
lab46:~/src/desig/fwf0$ chmod 0644 ~/public_html/fwf0.png
</cli>

Then, point a web browser at the following URL:

  * https://lab46.g7n.org/~yourusername/fwf0.png

NOTE: sometimes the web browser caches previous results, you may have to refresh a few times on revisions to get changes to manifest.
=====Submission=====
To successfully complete this project, the following criteria must be met:

  * Code must compile cleanly (no notes, warnings, nor errors)
  * Output must be correct, and match the form given in the sample output above.
  * Code must be nicely and consistently indented
  * Code must be well commented
  * Do NOT double space your code. Group like statements together.
  * Output Formatting (including spacing) of program must conform to the provided output (see above).
  * Track/version the source code in a repository
  * Submit a copy of your source code to me using the **submit** tool.

To submit this program to me using the **submit** tool, run the following command at your lab46 prompt:

<cli>
lab46:~/src/cprog/fwf0$ submit cprog fwf0 fwf0.c
Submitting cprog project "fwf0":
    -> fwf0.c(OK)

SUCCESSFULLY SUBMITTED
</cli>

You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches.

What I'll be looking for:

<code>
26:fwf0:final tally of results (26/26)
*:fwf0:proper output formatting per specifications [13/13]
*:fwf0:no negative compiler messages for program [7/7]
*:fwf0:code is pushed to lab46 semester repository [6/6]
</code>

Additionally:
  * Solutions not abiding by spirit of project will be subject to a 25% overall deduction
  * Solutions not utilizing descriptive why and how comments will be subject to a 25% overall deduction
  * Solutions not utilizing indentation to promote scope and clarity will be subject to a 25% overall deduction
  * Solutions not organized and easy to read are subject to a 25% overall deduction
