Description Author

This object can rescale images smoothly using HTML canvas objects.

It can take an image given the image object or a selector string of the image element to rescale.

The object can create a canvas to render the image rescaled to a given ratio or to a given size optionally preserving the original image proportions.

The image can be rescaled smoothly if the browser supports the imageSmoothingEnabled property. The smoothing level is configurable.

The object calls a given callback function when the rescaling is done passing the canvas object that contains the rescaled image.

One way to rescale images on a browser is to use canvas objects and create copies of the original images at different sites.

Modern browsers support a property named imageSmoothingEnabled that can be used to create smooth versions of rescaled images. That property may have a slightly different name depending on the browser type.

This object can create smooth rescaled images on several different browsers that support that feature.
