Converts grayscale input image to "string art," winding black thread around pins arranged around a circular white canvas, upscaling the output image resolution as described by Birsak et. al..
See my blog article for details.
Command line arguments specify the grayscale input image filename, upscaling block size, number of pins, and output image filename. Image files are in Netpbm 8-bit grayscale binary "P5" format (comments in the image file header are not supported).
For example, given a 512x512 image file input.pgm, the following will
create a 4096x4096 output.pgm image file using 256 pins:
string_art input.pgm 16 256 output.pgm
