MyTLAB

Basic plotting using C++. A big hw of Basic Programming in Year 1. I am assigned with Part 2(basic plotting). Part 2 is completed. The whole thing is not.

upd 2021.12.21 It is pain to merge this project with other students. They dont know how to write C++ with headers and they preferred a project in ONE file. The merged work is done, but it will not be uploaded.

Additional Features

1. Antialiasing is implemented when drawing numbers and drawing lines.
2. Bar charts support negative heights. In that case the bar is going downwards from zero.
3. Easy build with bat files. Good structure.

Something random

IDK why they let us do the three parts separately. I have to complete some of others' job to make my code run.

However, I copied code from the Internet(details below) to make up some of Part 3. I hope that won't win me a penalty.

The three parts are totally NOT equal. My part is the most troublesome.

Examples

How to use

1. Clone this repo. BMPFILE.h, cbmp.c/h, main.c, matrix.c/h, painter.c/h, ref24.bmp are core files.
2. Under Windows with MinGW64, clean then build then main.
3. Then you get the three imageschart_bar.bmp, chart_line.bmp, chart_scatter.bmp.

The CBMP library has a bug in it. The _get_int_from_buffer often accesses invalid memory addresses. The bug is fixed in this project.

Bugs Features & Todo

1. Not well tested. Never tried on a rectangluar setup where the two sides are of different lengths and ratios of scaling.
2. IDK how to include things properly. So I #include "xxx.c" instead of #include "xxx.h".
3. I mix the colors. So new paints won't cover the old. They mix with the old.
4. Two unknown fellows are going to help me complete the whole job. This is not the complete version of the whole thing.
