How to Use 🚀

$ ./img2vec
Usage: ./img2vec [options] file

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