vectorize-pixelart

Convert a PNG to a vector image format

$ vectorize-pixelart [path/to/input.png] [path/to/output.svg|.eps]

vectorize-pixelart [OPTIONS] <input-file> [output-file]

<input-file>
    Specifies the path to the source pixel art image file (e.g., .png, .gif, .bmp) that needs to be vectorized.

[output-file]
    Specifies the path for the generated vector graphics file. The extension typically determines the output format (e.g., .svg, .eps). If omitted, output might be directed to stdout or a default filename derived from the input.

-t, --threshold <value>
    Sets the color difference threshold for edge detection. A lower value detects more subtle color changes as edges, potentially creating more paths. Values typically range from 0 to 255.

-c, --colors <num>
    Reduces the image to a specified number of colors before vectorization. Useful for simplifying complex pixel art or achieving a specific palette look.

-s, --smooth
    Applies a smoothing algorithm to the vectorized paths, potentially rounding sharp corners or simplifying jagged lines. Use with caution to preserve the original pixel art aesthetic.

-f, --format <fmt>
    Specifies the output vector format (e.g., svg, eps, pdf). This option overrides the format implied by the [output-file] extension.

-v, --verbose
    Enables verbose output, showing progress and detailed information about the vectorization process.

-h, --help
    Displays the help message and exits.

The vectorize-pixelart command is a conceptual utility designed to transform low-resolution pixel art raster images into smooth, scalable vector graphics. It aims to accurately detect the distinct blocks of color and sharp edges characteristic of pixel art and convert them into precise vector paths, typically in formats like SVG. This process allows pixel art to be scaled infinitely without loss of detail or introduction of pixelation, making it ideal for high-resolution displays, print, or responsive web design where crisp, clean lines are paramount. While maintaining the original aesthetic, it provides the flexibility of vector formats, suitable for game development assets, logos, and digital illustrations.

Please note: "vectorize-pixelart" is not a standard or widely distributed Linux command. This analysis provides a conceptual representation of what such a command would likely entail, based on its descriptive name and common image processing utilities. Actual tools for vectorizing pixel art often exist as part of larger image manipulation suites (like Inkscape's Trace Bitmap feature) or specialized scripts. Be aware that the quality of vectorization can vary greatly depending on the input pixel art's complexity and the algorithm's sophistication, potentially requiring manual cleanup for perfect results.

The hypothetical operation of vectorize-pixelart would involve several image processing steps:

1. Color Quantization: Reducing the number of distinct colors in the image.
2. Edge Detection: Identifying the precise boundaries between different color regions or distinct pixels.
3. Path Tracing: Converting these detected edges into mathematical vector paths, often using algorithms that fit Bezier curves or polygons.
4. Path Simplification: Optimizing the number of points in the vector paths to reduce file size and improve smoothness without losing critical detail from the original pixel art.
