Investigate better SVG code parsing

[tomayac]

Maybe use https://github.com/WebReflection/linkedom for

SVGcode/src/js/colorworker.js

Lines 69 to 88 in 1def07e

	svg = svg.replace(
	'fill="#000000" stroke="none"',
	`fill="rgb(${r},${g},${b})" stroke="rgb(${r},${g},${b})"${
	a === '255'
	? ''
	: ` fill-opacity="${alpha}" stroke-opacity="${alpha}"`
	} stroke-width="${params.strokeWidth}px"`,
	);
	const pathRegEx = /<path\s*d="([^"]+)"\/>/g;
	let matches;
	const shortPaths = [];
	while ((matches = pathRegEx.exec(svg)) !== null) {
	const path = matches[1];
	if (path.split(' ').length < params.minPathSegments) {
	shortPaths.push(matches[0]);
	}
	}
	shortPaths.forEach((path) => {
	svg = svg.replace(path, '');
	});

Well done, really great job... I'm interested in improving the performance/speed of this tool, do you have any pointers where I should start from?

The present issue is purely about replacing string-based replacement with proper DOM parsing.

If you are interested in improving the performance: see tomayac/esm-potrace-wasm#8. The latest version of esm-potrace-wasm is capable of dealing with color, but fails on too large inputs.
