The algorithm processes the image in the following way:
```
Retrieve photo as an array of pixels IMAGE
Set desired number of horizontal lines as LINE_COUNT
Set desired number of vertical spacing as SPACING
Set desired line amplitude as AMPLITUDE
Set desired line rotation frequency as FREQUENCY
For y :=0 to image height step image height / LINE_COUNT do
Set startx := 0
Set starty := y
Create a set of coordinates as [startx, starty]
For x := 1 to image width step SPACING do
Get brightness br of the current pixel as average of r,g,b values
Set r := (255 - br) / LINE_COUNT * AMPLITUDE
Set a := (255 - br) / FREQUENCY
Create a set of coordinates as [x, y + Math.sin(a) * r]
Pass the resulting array of coordinates to rendering application
```
# Using the output images
The output SVG file generated with this tool can be uploaded to SVG -> GCODE (or similar) converter in order to be plotted on a pen plotter or engraved on a laser cutter.
