+# brline
+simple bresenham line drawing algorithm demonstration implemented with golang,
+this was my last week lesson in computer graphics class with Dr. Behzad Zamani
+
+### how to compile
+in order to compile and run this project you need to install [go compiler](https://go.dev/dl),
+after that run `go build` in project directory to compile brline binary
+
+```
+# git clone https://git.snix.ir/brline
+# cd brline && go build 
+# ./brline
+```
+
+### how to use
+use `./brline --help` to print help banner, you need to provide 2 points as start and end of the line  
+each point has x and y coordinate, so for starting point you should use -xa and -ya flags and for ending point -xb and -yb
+
+```
+# ./brline --help
+usage of bresenham line simulator:
+./brline options...
+
+options:
+  --pt  <file>      named png file to save bresenham output
+                    default path for this file is br_resualt.png
+
+  --xa  <uint>      x coordinate of starting point
+  --xb  <uint>      x coordinate of ending point
+
+  --ya  <uint>      y coordinate of starting point
+  --yb  <uint>      y coordinate of ending point
+
+example:
+   ./brline --pt mytest.png --xa 8 --ya 3 --xb 2 --yb 10
