-#### Caveat ####
-Each browser limits [the maximum size](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/canvas#maximum_canvas_size) of a Canvas object. <br/>
-So, we resize the image to less than the maximum size that each browser restricts. <br/>
-(However, the `proportion/ratio` of the image remains.)
