To create a program that generates an image containing a set of letters, made from coordinated blocks.

For this project, you will be using a graphics design library to render the indicated image.

It is your task to write a program that generates an image containing the representation of a set of letters, in the current directory as your source code and binary, named and accessible as lob0.png

The program will be an exercise in exploration: you will be given some example code that does something. You should poke at it to gain deeper understanding. Then you will, taking out the demo graphics, lay out a set of letters:

• 4 letters
  • each letter is a unique render (if you had 2 letter M's, both M's should look different)
  • the 4 letters are arranged to comfortably fit within a canvas of 1280×1024 pixels
  • the image will utilize no fewer than 8 different colours
  • letters are to be entirely constructed out of blocks (filled but square rectangles), no smaller than 40×40 pixels a piece (all blocks must be the same size)

Letters could be your initials, plus extra to fill up to 4 total letters.

Restrictions:

• I don't want to see all simple letters (4 L's, 4 I's, etc.)

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

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

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

lab46:~/src/c4eng$ grabit c4eng lob0
make: Entering directory '/var/public/SEMESTER/c4eng/lob0'
'/var/public/SEMESTER/c4eng/lob0/Makefile' -> '/home/user/src/c4eng/lob0/Makefile'
'/var/public/SEMESTER/c4eng/lob0/lob0.c' -> '/home/user/src/c4eng/lob0/lob0.c'
make: Leaving directory '/var/public/SEMESTER/c4eng/lob0'
lab46:~/src/c4eng$ 

At which point you can change into the newly created and populated lob0 directory.

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

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:

lab46:~/src/c4eng/lob0$ submit c4eng lob0 lob0.c
Submitting c4eng project "lob0":
    -> lob0.c(OK)

SUCCESSFULLY SUBMITTED

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:

26:lob0:final tally of results (26/26)
*:lob0:proper output formatting per specifications [13/13]
*:lob0:no negative compiler messages for program [7/7]
*:lob0:code is pushed to lab46 repository [6/6]

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
