# raster-to-vector

A fast way to convert rasterized straight edges into vectors.

![](./imgs/01.png) ![](./imgs/02.png)

If given the pixel pattern data of a line bit by bit, it is possible to determine if a line is straight without using loops or slow calculus functions.

This is implemented in the "rastToVec.c" source code.

In the "tests/line_patt" folder the output of the fast method is tested using the output of a different and more slower method.

Objective: to create code that...

* quickly converts edges into vectors

* is practical and easy to use

* uses a single c source code file

Applications:

* landscaping

* home decorating

* CAD

* augmented reality

* real time 3d modeling of the real world

* camera based collision detection systems

Todo List:

* Write edge tracer code

* Demonstrate raster to vector conversion
