Gaussian smoothing function

[cs1h]

Hi,

 

Does anyone know of a good Gaussian smoothing function?

 

Thanks,

I doubt the GD library could handle such complex things..

imagefilter()

 

Filter Types:

    * IMG_FILTER_NEGATE: Reverses all colors of the image.

    * IMG_FILTER_GRAYSCALE: Converts the image into grayscale.

    * IMG_FILTER_BRIGHTNESS: Changes the brightness of the image. Use arg1 to set the level of brightness.

    * IMG_FILTER_CONTRAST: Changes the contrast of the image. Use arg1 to set the level of contrast.

    * IMG_FILTER_COLORIZE: Like IMG_FILTER_GRAYSCALE, except you can specify the color. Use arg1 , arg2 and arg3 in the form of red , blue , green and arg4 for the alpha channel. The range for each color is 0 to 255.

    * IMG_FILTER_EDGEDETECT: Uses edge detection to highlight the edges in the image.

    * IMG_FILTER_EMBOSS: Embosses the image.

    * IMG_FILTER_GAUSSIAN_BLUR: Blurs the image using the Gaussian method.

    * IMG_FILTER_SELECTIVE_BLUR: Blurs the image.

    * IMG_FILTER_MEAN_REMOVAL: Uses mean removal to achieve a "sketchy" effect.

    * IMG_FILTER_SMOOTH: Makes the image smoother. Use arg1 to set the level of smoothness.

    * IMG_FILTER_PIXELATE: Applies pixelation effect to the image, use arg1 to set the block size and arg2 to set the pixelation effect mode.
