This is not possible, though you could just produce an image
representing the exponent and feed that as an input image to your
custom blur.

The original MATLAB code has a gaussian blur whose value changes
based on pixel, so I thought I could this by using a core image
kernel to figure out the calculations, then feed the exponent of
the E term to the radius input of the gaussian blur.
No such luck.
I can do the required calculations. I use image only to determine
what value the euclidean distance map function will return. the
division, rounding and multiplying all are more or less ok.
I cannot output the exp term. Kernels only output images.
so I turned my sorry fate over to a Javascript block but wait!!
How will I get an image into javascript so I can get the coordinates
of the day ( as samplercoords does in kernels )?
Thats my question. Is there any way either inside a javascript
block to determine the coords of the current pixel or outside a
java block by having a patch send me the current coords?
any help is appreciated.
