Image dataUrl support?

[jianghai]

const img = new Image();
img.src = <Buffer>

I have image data which is dataUrl，Though dataUrl could be parsed to buffer Buffer.from(dataUrl.split(',')[1], 'base64'); but brings a little performance loss.

Data uri is supported via loadImage function

import { loadImage } from '@napi-rs/canvas'

const image = await loadImage('dataUri')

You can also find the test for it here

canvas/__test__/loadimage.spec.ts

Lines 33 to 38 in 171a20e

	test('should load data uri', async (t) => {
	const img = await loadImage(
	'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAIAQMAAAD+wSzIAAAABlBMVEX///+/v7+jQ3Y5AAAADklEQVQI12P4AIX8EAgALgAD/aNpbtEAAAAASUVORK5CYII',
	)
	t.is(img instanceof Image, true)
	})
