Crosshatcher renders an image in a crosshatching technique via an interesting method.
Note, the image must be grayscale (to convert to grayscale in Gimp, Image->Mode->grayscale)
By default the input image is in "image.jpg". Output files are: "output.png" and "lines.txt", and "lines.svg".
You can specify the input image and output file width, line spacing and number of layers. For example:
./crosshatcher input-file.jpg 1000 10 5
uses input-file.jpg as the input file, and produces output 1000 units wide with line spacing of 10 units and 5 layers of lines.
