DESCRIPTION: SURROUNDBLUR creates a blurred background region around the input image. A border and or drop shadow may be added between the image and the blurred background. ARGUMENTS: -r resize ... RESIZE of input image expressed as WxH in pixels or in percent as WxH%. The default is the original input size. The resize value should be smaller than the bgsize. -b bgsize ... BGSIZE is the blurred background size expressed as WxH in pixels or in percent as WxH%. The default is twice the original input size. The bgsize should be larger than the resize. -s smoothing ... SMOOTHING (blurring) amount to apply to the input to create the background. Values are integers>=0. The default=50. -c color ... COLOR is the border color. Any valid opaque IM color is allowed.
