*
|
||||
* blur version 2.1 (10 June 2004 WES)
|
||||
* history
|
||||
* 2.1 - 10 June 2004 WES
|
||||
* removed dialog along with randomization and repeat options
|
||||
* 2.0 - 1 May 1998 MEO

* based on randomize 1.7
|

*
|
||||
* Please send any patches or suggestions to the author: meo@rru.com .
|
||||
*
|
||||
* Blur applies a 3x3 blurring convolution kernel to the specified drawable.
|
||||
*
|
||||
* For each pixel in the selection or image,
|
||||
* whether to change the pixel is decided by picking a
|
||||
* random number, weighted by the user's "randomization" percentage.
|
||||
* If the random number is in range, the pixel is modified. For
|
||||
* blurring, an average is determined from the current and adjacent
|
||||
* pixels. *(Except for the random factor, the blur code came
|
||||
* straight from the original S&P blur plug-in.)*
|
||||
*
|
||||
* This works only with RGB and grayscale images.
