A jQuery UIplugin
that captures or draws a signature.
It requires the jQuery UI widget and mouse modules and needs the
excanvas.js add-in for older IE versions.
The current version is 1.2.1 and is available

Few films have the power to unsettle, amuse, and intellectually provoke quite like Luis Buñuel’s 1962 surrealist masterpiece, The Exterminating Angel (Spanish: El ángel exterminador ).

The film is teeming with Buñuel’s signature motifs: the obsession with feet, the juxtaposition of religious iconography with blasphemous acts, and the recurrence of animals (sheep and bears wander through the house as the chaos escalates). These surreal touches serve to destabilize the viewer, creating a dreamscape where logic is suspended.
Since I can't build software directly, here's a you could give to a developer or use to design a "Watch The Exterminating Angel" feature:
Options
Customise the signature functionality through additional settings.
Using metadata for configuration may require adding the jquery.metadata.js plugin to your page.
Events
You can be notified when the signature has changed via the change setting.
And you can erase the signature with the clear command and
test for any content via the isEmpty command.
Extract the signature as a JSON value, and later re-draw it from that value.
Alternately you can generate the signature as SVG, or as a data URL in PNG or JPEG format.

C# Rendering
You can render an image from the signature JSON text on the server.
The following shows how to do this in .NET 4.5 C#, thanks to Daniel Knight.
You would call this code as follows
and it returns a base64 encoded byte array as a string:
GetBase64Png(jsonEncoding, width, height);
using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Web.Http;
public class GraphicsController : ApiController
{
[HttpGet]
[ActionName("GetBase64Png")]
public string GetBase64Png([FromUri] string linesGraphicJSON, [FromUri] int width, [FromUri] int height)
{
return Draw2DLineGraphic(new JavaScriptSerializer().Deserialize<Signature>(linesGraphicJSON), width, height);
}
private string Draw2DLineGraphic(I2DLineGraphic lineGraphic, int width, int height)
{
//The png's bytes
byte[] png = null;
//Create the Bitmap set Width and height
using (Bitmap b = new Bitmap(width, height))
{
using (Graphics g = Graphics.FromImage(b))
{
//Make sure the image is drawn Smoothly (this makes the pen lines look smoother)
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
//Set the background to white
g.Clear(Color.White);
//Create a pen to draw the signature with
Pen pen = new Pen(Color.Black, 2);
//Smooth out the pen, making it rounded
pen.DashCap = System.Drawing.Drawing2D.DashCap.Round;
//Last point a line finished at
Point LastPoint = new Point();
bool hasLastPoint = false;
//Draw the signature on the bitmap
foreach (List<List<double>> line in lineGraphic.lines)
{
foreach (List<double> point in line)
{
var x = (int)Math.Round(point[0]);
var y = (int)Math.Round(point[1]);
if (hasLastPoint)
{
g.DrawLine(pen, LastPoint, new Point(x, y));
}
LastPoint.X = x;
LastPoint.Y = y;
hasLastPoint = true;
}
hasLastPoint = false;
}
}
//Convert the image to a png in memory
using (MemoryStream stream = new MemoryStream())
{
b.Save(stream, ImageFormat.Png);
png = stream.ToArray();
}
}
return Convert.ToBase64String(png);
}
public class Signature : I2DLineGraphic
{
public List<List<List<double>>> lines { get; set; }
}
interface I2DLineGraphic
{
List<List<List<double>>> lines { get; set; }
}
}
