Description
It occurs in this function,
function isDataURL(url) {
var dataURLRegex = /^\s*data:([a-z]+\/[a-z]+(;[a-z\-]+\=[a-z\-]+)?)?(;base64)?,[a-z0-9\!\$\&\'\,\(\)\*\+\,\;\=\-\.\_\~\:\@\/\?\%\s]*\s*$/i;
return !!url.match(dataURLRegex);
}
I am passing it like this,
leafletImage(map.leafletElement, fn(err, canvas){
});
map is a react leaflet map
