Auto Outline in PSP?

[Totoro]

Hi there,
can someone help me a bit about Paintshop Pro? I made a character-set, but on the edges its a bit blurry, and when the character walks in front a different color, it looks strange. That's why I would like the outline of the sprites, that means always the last pixel before the sprite ends (if you know what I mean...) black. Theoretically its no problem doing that by hand, but isn't there something like an auto-outline function or a trick which can save me from doing the outlines for all the sprites I have now?

First, make a selection of the sprite using the magic wand.
Then go to the selections menu - modify - expand with one pixel.
Last, use the color replacer tool to outline tha sprite.
Cheers

if your brush stroke is larger than 4 pixels it will be anti-aliased, to stop this happening adjust the hardness to 100, or if you're using shapes to draw the characters unselect "antialias" and "retain style"

Create a new layer
Select your sprite with the magic wand tool
Modify>Selections>Expand>1 pixel (higher number = thicker outline)
Fill the selection with the outline colour you want
Modify>Selections>Contract>1 pixel
Press delete!

Thank you everyone for your friendly advise! I managed to do it now. This anti-alliassing stuff is supposed to make the pictures look cooler, but for us its really a pain in the neck.
