Re: Is it possible to resize an image of 4 Kb to 725 bytes with some filter without loosing the form

Thanks to all users that have replied to my question, I have applied all 
suggestion but the best result that I have produced is this image:
http://img706.imageshack.us/img706/7601/foxd.png

of 742 bytes (not 725), if I remove the transparent background I am able 
to obtain a good Face image.

I have applied the option -colors 16 to obtain this image from original:

convert fox.png -geometry 48x48 -colors 16 -strip fox2.png


The strange (for me) thing is that if I apply -colors 15 I obtain an 
image of 930 bytes (bigger in size).
I think that I use the image with the white background without transparency


Thanks again for your help.
