Re: intersted in 'Put alpha-transparent pngs onto cam image'

["Ankur Modi" <modinsit gmail com>]

in ur previous mail you said that just doing alpha-transparent png could be too
little for 3 months developing.so i want to do 'hackergotchi creation' also .it can be implemented in following steps:-

1.cut out the required part of a image by using 'Select
contiguous regions' and 'Select hand-drawn regions'.

 'select contiguous region'  can be implemented by selecting areas contiguous to the cursor, based on color.  From the current
pixel, each adjacent     pixel is checked. 
'select hand-drawn region' can be implemented by pressing the Select Mouse Button anchors a point, from which a line
is drawn following the cursor.  Releasing the cursor finishes the
selection by drawing a straight line from the current cursor location
to the starting point.  This allows to select virtually any shape,
including complex shapes, figure eights, or anything else.

2.feathering operation is performed  by gaussian blur to remove sharp edges and we get anti-aliased edge.

3.and finally we can apply shadow algorithms using openGL to get the hackergotchi.

M i on a right path?

personally, but then please do not just click "reply".

you can find the cheese ideas here: http://live.gnome.org/Cheese/Ideas

it would be your task do see what has to be done and how you could
accomplish it. application writing ;)
