If you have GraphicConverter, place the object on a contrasting background and systematicaly remove all the background. The outline is not pure white but actually a light bleeding of the color and it will show up as white on a darker base.

Find those areas you missed the first time around. You'll want to explore those hidden areas now made accessible with Spells Expander.

Besides the above:

To get rid of the white border around images:

In Fireworks:
(list=1)
Must be in bitmode
Change the canvas to black so you can see what you're doing
Magic wand in the white
Erase all the white (magic wand still on)
Click magic wand in used-to-be white to turn it off
Carefully erase all off-white around your image
Change the canvas to white
Save as pict file
(/list=a)

In Photoshop:

(list=1)
1. Open your PICT (.pct) image in Photoshop (I have 7.0)
2. Make the image window large enough to see gray around the image.
3. Click on the Magic Wand
4. Click the Magic Wand in the white area away from your image
5. Edit >Stroke
a. width = 2 pixels
b. color = black (000000)
c. location = center
d. mode = Color burn
e. opacity = 100%
6. Click Okay and you've got a black stroke
7. Click the Magic Wand in the gray area to reset it
8. Zoom into the image about 7 times
9. Magic Wand click into the STROKE (the black line you just made)
10. Image >Adjustments
a. Replace Color
b. Leave all as is EXCEPT
(1) Drag Lightness all the way to the right to +100
11. Save image
(/list=a)

USE ALPHA CHANNELS!!!

BUT YOUR GAME HAS TO USE TRUE COLOR IN THE GAME OPTIONS OTHERWISE THIS WILL NOT WORK!!!

By using alpha channels you can create partly invisible edge pixels. By doing this you can create characters/animations/stamps that blend seamlessly with your background, no matter what color, no matter how irregular.

If you don't do that you will get pictures with rough edges instead of pictures with smooth edges.

There are several primers out there that can explain how to work with alpha channels, but this is how I did it with my walking animations:

- I created a bunch of anim picts from poser with a background color that was not in the figure I was exporting. In this case it was purple.
- In photoshop:
-- I selected the entire image, copied it, deleted the background and pasted the copied image on it. In this way I created a picture with one layer and no background layer.
-- selected the purple color with the eye dropper
-- I selected the purple color using color selected > sampled color
-- I erased the selection
-- Part of the image is now invisible and the edge pixels are now partly invisible
-- export the pict as png (png 24) with alpha channels. In photoshop it is best to do this with web export since this results in smaller images

I made this into an action in photoshop so I could use it on a batch of pictures.
