"Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The canvas has been tainted by cross-origin data."

When giving an image from an external source, this error pops up.

This article is proposing a solution for this. For solving the issue, you have to modify these.

1. Client side img object: img.crossOrigin="Anonymous"
2. Server side header: "Access-Control-Allow-Origin: *"

The error is triggered even for images with valid image-source.

Add a feature which allows the users to pass an array as a function argument containing the characters to avoid while generating the ASCII image.
