description: Blur input stream, and subtract the result from the input image. This is not a mathematically correct Laplacian (which would be the sum of second derivatives over X and Y).
Uses the 'vanvliet' and 'deriche' functions from the CImg library.
CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).

title: Size
description:
Size (diameter) of the filter kernel, in pixel units (>=0). The standard deviation of the corresponding Gaussian is size/2.4. No filter is applied if size < 1.2.

title: Uniform
description:
Apply the same amount of blur on X and Y.
type: boolean
readonly: no
required: no
animation: yes
default: 1
title: Filter
description:
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.

title: (Un)premult
description:
Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
type: boolean
readonly: no
required: no
animation: yes
title: Invert Mask
description:
When checked, the effect is fully applied where the mask is 0.
type: boolean

required: no
animation: yes
title: Mix
description:
Mix factor between the original and the transformed image.

required: no
animation: yes
minimum: 0

default: 1
title: Top-Left Origin
description:
Set to 1 to use MLT top-left image origin instead of the OFX bottom-left origin. Use for plugins that crash or produce incorrect output with negative row bytes.
