[Bang Pham Huu]

WCPS query

for c in (rgb) return encode(
(unsigned char)
coverage filteredImage 
over $px x(10:240),$py y(10:230)
values condense +
over $kx x(-1:1),$ky y(-1:1)
using(
coverage kernel 
over $x x (-1:1),$y y(-1:1)
value list < 1; 1; 1; 0; 0; 0; -1; -1; -1 >)
[x($kx),y($ky)]*(c[i($px+$kx),j($py+$ky)]).red, "png", "nodata=0")

does not work if has negative numbers

< 1; 1; 1; 0; 0; 0; -1; -1; -1 >
