Create an instance of Identicon

There are mainly two ways of creating an instance of Identicon:

• Identicon.FromHash(hash, size)

  Creates an instance with a hash value. You can either provide a byte array containing the hash, or provide a hexadecimal hash string. At least 6 bytes are required in byte arrays and 12 characters in hash strings.

• Identicon.FromValue(value, size[, hashAlgorithmName])

  Jdenticon-net will create a hash for you using the specified hash algorithm. You can provide any object, even null, as argument. Jdenticon will use ToString to get a string representation of the object and then push the UTF8-encoded string through the specified hash algorithm. If no hash algorithm is specified Jdenticon-net will default to SHA1.

Generate an icon

There are multiple methods in the Identicon class for generating icons:

• SaveAsPng(path|stream)

  Generates an icon and saves it as a PNG image.

• SaveAsSvg(path|stream|TextWriter)

  Generates an icon and saves it as an SVG image.

• ToSvg([fragment])

  Generates an SVG string containing an icon. This can be useful for embedding icons in other SVG files or inlining SVG icons on your website. For creating SVG files, please use Save.

Change icon appearance

You can customize the colors of the generated icons, by using IdenticonStyle. The easiest way of creating a new style is to use the icon designer.

Advanced customizations

By subclassing Jdenticon.IconGenerator you can completely override the look of your icons. Set the Identicon.IconGenerator property to an instance of your own generator to make use of the customized icon generator.
