blobs v2.3.0-beta.2

The legacy API exists to preserve compatibility for users importing the package using a script tag. Because unpkg.com serves the latest version of the package if no version is specified, I can't break backwards compatibility, even with a major release. This API also preserves a few features that could potentially still be useful to some users (guide rendering and editable svg).

Install

// $ npm install blobs
const blobs = require("blobs");

<script src="https://unpkg.com/blobs"></script>

Usage

const svg = blobs(options);

Options are not sanitized. Never trust raw user-submitted values in the options.

Options

Required

Optional

Either stroke or color must be defined.

Guides will use stroke color and width if defined. Otherwise, they default to black stroke with width of 1.

Example Options Object

const options = {
    size: 600,
    complexity: 0.2,
    contrast: 0.4,
    color: "#ec576b",
    stroke: {
        width: 0,
        color: "black",
    },
    guides: false,
    seed: "1234",
};

Advanced

If you need to edit the output svg for your use case, blobs also allows for editable output.

const editableSvg = blobs.editable(options);

The output of this function is a data structure that represents a nested svg document. This structure can be changed and rendered to a string using its render function.

editableSvg.attributes.width = 1000;
const svg = editableSvg.render();

New elements can be added anywhere in the hierarchy.

const xmlChild = blobs.xml("path");
xmlChild.attributes.stroke = "red";
// ...
editableSvg.children.push(xmlChild);
