gaussianBlurConvolve

Return an instance of TextureOp which implements a convolution from the source texture to the destination texture provided a Gaussian blur effect for textures, and its convolve kernel conforms to the Gaussian distribution with sum of 1, and the kernel is a 3 * 3 matrix, and the length should be odd.

For the edge pixels of the image, the default value of missing pixels within the convolution radius is set to 0 when performing convolution operations.

Return

an instance of TextureOp which implements a convolution from the source texture to the destination.

Parameters

factor

the factor of the transparency and brightness.

length

the length of the kernel.
