This is a demo for a Javascript / Canvas based implementation of my
StackBlur algorithm.
Usage: stackBlurImage( sourceImageID, targetCanvasID, radius, blurAlphaChannel );
or: stackBlurCanvasRGBA( targetCanvasID, top_x, top_y, width, height, radius );
or: stackBlurCanvasRGB( targetCanvasID, top_x, top_y, width, height, radius );

Thank you to
Mike Shaver for fixing my first slider implementation.
Thanks to Michael Deal for noticing and fixing the ARGB/RGBA mixup and the pre-multiplied alpha bug.
For some slightly faster box blurs which do not look as good though check out my
Superfast Blur,
StackBox Blur and
Integral Image Blur.
For a speed comparison of all 4 blur algorithms check
this jsPerf test.
