I'm not doing the "average" anywhere in this particular blur. It's a
built in convolution operation.
The code is super simple:
op = createObject("java","java.awt.image.ConvolveOp");
blurredImage =
createObject("java","java.awt.image.BufferedImage").init(
img.getWidth(), img.getHeight(), img.getType());
op.init(variables.kernel, op.EDGE_NO_OP, javacast("null",""));
op.filter(img, blurredImage);
return blurredImage;
The kernel in this case is just a simple array where each element in the
array is the same... ie, for a bluramount of 3, the array used to create
the kernel 9 elements, each 0.1111
Most everything I know about blurring images comes from this fabulous
page, btw:
