jSignature is a jQuery plugin which simplifies creation of a signature capture field in the browser window, allowing a user to draw a signature using mouse, pen, or finger.
jSignature captures signature as vector outlines of the strokes. Although jSignature can export great bitmap (PNG) too, extraction of highly scalable stroke movement coordinates (aka vector image) of the signature allows much greater flexibility of signature rendering.
A extra effort (through smoothing and pressure simulation) is made to make the strokes look pretty on the screen while these are drawn by the signor.All major desktop, tablet and phone browsers are supported. HTML5 Canvas element is used by default. We fall back on Flash-based Canvas element emulator (FlashCanvas) when actual Canvas is not supported by the browser (Iinternet Explorer v.8 and lower).Tags: HTML5 canvas
