All parameters constructor.

Parameters:

url - Image resource URL (e.g. http://www.website.com/image.png)

reqWidth - Required width of the view where the Bitmap should fit. This parameter doesn't affect image aspect ratio, it's only used to calculate the inSampleSize of the image in case a downsample is required.

reqHeight - Required height of the view where the Bitmap should fit. This parameter doesn't affect image aspect ratio, it's only used to calculate the inSampleSize of the image in case a downsample is required.

onBitmapRendered - Overwrite this callback to retrieve Bitmap object rendered once it's ready and perform any other actions needed.

onBitmapRenderFailed - Overwrite this callback to perform actions when Bitmap object fails to render. Can be null.

epicBitmapCache - Cache to check if bitmap has already been rendered.
