Detailed Description

GRAY2Sobel filter. Applies a horizontal and vertical Sobel filter to a grayscale texture. Resulting texture channel values: .r = hEdge , .g = vEdge, b = norm(sobelHV) The resulting texture must support signed values and have double number of bits per channel.

Derived class from GpuStdShaders. ATTENTION: This filter works with a source texture of type GL_TEXTURE_RECTANGLE_ARB only.
