API

pattern = generate(input, options)

Returns a newly-generated, tiling SVG Pattern.

• input Will be hashed using the SHA1 algorithm, and the resulting hash will be used as the seed for generation.
• options.color Specify an exact background color. This is a CSS hexadecimal color value.
• options.baseColor Controls the relative background color of the generated image. The color is not identical to that used in the pattern because the hue is rotated by the generator. This is a CSS hexadecimal color value, which defaults to #933c3c.
• options.generator Determines the pattern. All of the original patterns are available in this port, and their names are camelCased.

pattern.color

Gets the pattern's background color as a hexadecimal string.

const pattern = generate('GitHub')
pattern.color // => "#455e8a"

pattern.toString() and pattern.toSvg()

Gets the SVG string representing the pattern.

pattern.toBase64()

Gets the SVG as a Base64-encoded string.

pattern.toDataUri()

Gets the pattern as a data URI, i.e. data:image/svg+xml;base64,PHN2ZyB....

pattern.toDataUrl()

Gets the pattern as a data URL suitable for use as a CSS background-image, i.e. url("data:image/svg+xml;base64,PHN2ZyB...").
