This library encapsulates interaction with the coin canvas server. The
CoinCanvasClient class includes access to all of the underlying APIs.
The library can be built with npm run build. Output files are placed into
dist and the package can be imported normally after it has been built.
Canvas data can be handled with the onFullCanvas and onUpdatedPixels
callbacks. The Canvas class provides access to an ImageData object that can
be used to create the initial canvas. PixelColour objects provide information
to update these pixels with Colour objects where CSS colour strings can be
obtained via cssStr().
CoinCanvasClient objects require a PixelAddrGenerator object which can be
provided using the P2putPixelAddrGenerator subclass. This expects 5 P2PUT
prefix bytes. To provide the "canvas" prefix [0xc7, 0x66, 0xce, 0xc1, 0xef]
can be used.
Usage examples can be seen in the tests under the tests/ directory.
