boxfilter

Built-in command

Arguments:

size[%]>=0,_order,_boundary_conditions,_nb_iter>=0 or
axes,size[%]>=0,_order,_boundary_conditions,_nb_iter>=0

Description:

Blur selected images by a box filter of specified size (fast recursive implementation).

order can be { 0:Smooth | 1:1st-derivative | 2:2nd-derivative }.
boundary_conditions can be { 0:Dirichlet | 1:Neumann | 2:Periodic | 3:Mirror }.
When specified, argument axes is a sequence of { x | y | z | c }.
Specifying one axis multiple times apply also the blur multiple times.

Default values:

order=0, boundary_conditions=1 and nb_iter=1.

Examples of use:

• Example #1

<a href="image.jpg" class="highslide" onclick="return hs.expand(this)">image.jpg</a> +boxfilter 5%

Command: <a href="image.jpg" class="highslide" onclick="return hs.expand(this)">image.jpg</a> +boxfilter 5%

• Example #2

<a href="image.jpg" class="highslide" onclick="return hs.expand(this)">image.jpg</a> +boxfilter y,3,1

Command: <a href="image.jpg" class="highslide" onclick="return hs.expand(this)">image.jpg</a> +boxfilter y,3,1
