Digital testing chart

I need you to develop some software for me. I would like this software to be developed for Linux using C. I am currently looking for someone to write a GUI application for Linux. The application is for a digital eye testing chart, like the one you see in optometrists when you 'read letters from the top line'. You would need to supply the complete source code including commenting written in C if possible. Please see the rough project outline below:

Operating System: Raspbian stretch with Desktop V4.9

Hardware: Raspberry pi 3b

Video output via hdmi

Screen Resolution: 1920x1080

Completely offline - no wifi/bluetooth functionality

Screen resolution is key in all concepts of this program (menus/tests)

Sony ‘XMB’ style look with colour themes (set by user)

7 key tests to be created along with Snellen, Tumbling E, Numbers, Duochrome balance, Cross cylinder dots and point of fix tests, will explain in further detail if we go ahead with the order.

Need a seperate quote for an additional 40 tests to be created.

Mostly black and white tests but some colour

Need to show on screen for tests:

Name of the test

Current contrast ratio (adjustable on button press)

Acuity scale (size of text, adjustable on button press)

Letters must be able to accurately scale at button press according to algorithm

Randomize letters on button press although remove some sequences (swear words)

Randomize must never repeat (within reason)

Must be able to play multimedia from sd card

Presets can be saved to sd card and loaded on startup

Error logging

Possibility for different languages in the future - hidden from user for this build. If you think you could be up for the job or have any further questions, please feel free to ask. Thanks.
