/*
|

* version 1.04
|

* This version requires GIMP v0.99.10 or above.

*
|

* This plug-in "pixelizes" the image.

* http://ha1.seikyou.ne.jp/home/taka/gimp/
|
||||
*
|
||||
* Changes from version 1.03 to version 1.04:
|
||||
* - Added gtk_rc_parse
|
||||
* - Added entry with scale
|
||||
* - Fixed bug that large pixelwidth >=64 sometimes caused core dump
|
||||
*
|
||||
* Changes from gimp-0.99.9/plug-ins/pixelize.c to version 1.03:
|
||||
* - Fixed comments and help strings
|
||||
* - Fixed `RGB, GRAY' to `RGB*, GRAY*'
|
||||
* - Fixed procedure db name `pixelize' to `plug_in_pixelize'
|
||||
*
|
||||
* Differences from Tracy Scott's original `pixelize' plug-in:
|
||||
*
|
||||
* - Algorithm is modified to work around with the tile management.
|
||||
* The way of pixelizing is switched by the value of pixelwidth. If
|
||||
* pixelwidth is greater than (or equal to) tile width, then this
|
||||
* plug-in makes GimpPixelRgn with that width and proceeds. Otherwise,
|
||||
* it makes the region named `PixelArea', whose size is smaller than
|
||||
* tile width and is multiply of pixel width, and acts onto it.
