## How to Use đ
```
$ ./img2vec
Usage: ./img2vec [options] file
Options:
-h Print this message
-o Output file name [default: img2vec.eps]
-svg Output file type as SVG [default: eps]
-c Reduce color [default: 32]
-b Blur image with specified scale
-n Enable noise removal (Gaussian blur)
-e Enable edge-preserving blur (blur non-edges)
-r Resize image to specified width or height
-d Enable debug mode
-x Enable dilation
-a Enable alpha channel processing
-cx Enable custom bit processing with specified bit value
-s Apply scaling with specified scale
-posterize Apply posterization with specified levels
-kmeans Apply k-means clustering with specified number of colors
-turd Set turdsize for potrace (removes small paths) [default: 2]
-alpha Set alphamax for potrace (edge smoothness) [default: 1.0]
-opttol Set opttolerance for potrace (curve optimization) [default: 0.2]
