oni-kun Posted August 17, 2009 Share Posted August 17, 2009 I doubt the GD library could handle such complex things.. Quote Link to comment https://forums.phpfreaks.com/topic/170720-gaussian-smoothing-function/#findComment-900412 Share on other sites More sharing options...
Prismatic Posted August 17, 2009 Share Posted August 17, 2009 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.
