A technical description of the algorithm is on [visioncortex.org/vtracer-docs](//www.visioncortex.org/vtracer-docs).
## Tech Stack
## Web App
VTracer and its [core library](//github.com/visioncortex/visioncortex) is implemented in [Rust](//www.rust-lang.org/). It provides us a solid foundation to develop robust and efficient algorithms and easily bring it to interactive applications. The supported target for now is WASM. It is interactive and fast, and is a perfect showcase of the capability of the Rust + HTML5 platform. We do plan to develop a command line program for VTracer.

visioncortex VTracer
A cmd app to convert images into vector graphics.
USAGE:
vtracer [OPTIONS] --input <input> --output <output>
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
--colormode <color_mode> True color image `color` (default) or Binary image `bw`
-p, --color_precision <color_precision> Number of significant bits to use in an RGB channel
-c, --corner_threshold <corner_threshold> Minimum momentary angle (degree) to be considered a corner
-f, --filter_speckle <filter_speckle> Discard patches smaller than X px in size
-g, --gradient_step <gradient_step> Color difference between gradient layers
-i, --input <input> Path to input raster image
-m, --mode <mode> Curver fitting mode `pixel`, `polygon`, `spline`
-o, --output <output> Path to output vector graphics
--preset <preset> Use one of the preset configs `bw`, `poster`, `photo`
-l, --segment_length <segment_length>
Perform iterative subdivide smooth until all segments are shorter than this length
-s, --splice_threshold <splice_threshold> Minimum angle displacement (degree) to splice a spline
```
