This Python script seamlessly converts PNG images to SVG format using two distinct methods:

In the pixel-wise conversion, each pixel within the PNG image transforms into an independent rectangle within the SVG file.

For the contiguous conversion, adjacent pixels of the same color in the PNG image unite, forming filled shapes in the SVG file.

The script utilizes the Python Imaging Library (PIL) for efficient image data manipulation. It navigates command-line argument intricacies with the OptionParser module. To perform an array of operations on tuples, the script turns to the operator module as a key resource.

Main functions:

add_tuples: Calculates the sum of corresponding elements from two tuples.

calculate_direction: Begins the computation of the direction vector between two points.

normalize_vector: Ensures the balance by normalizing a vector to possess a unit magnitude.

create_svg_header: Crafts the header for an SVG file with specified width and height.

convert_rgba_image_to_svg_pixels: Transforms a PNG image into SVG pixel by pixel.

find_joined_edges: Finds connected edges within a set of assorted edges.

convert_rgba_image_to_svg_contiguous: Shapes a PNG image into SVG, creating contiguous color regions.

png_to_svg opens a PNG file, converts it to RGBA format, and then uses the appropriate conversion function based on designated options.

The script also incorporates a segment for handling command-line options using OptionParser.

To use the code, the raster PNG image should be in the same directory.
