just out of curiosity, what made you convert the mask to a path at step 3? Why not simply choose Mask>Create>Brushstroke from Mask and then all is done? As per your method - it does not give a perfect clean effect.
that is one of the things I love about PhotoPaint and Draw - it does not matter how long you have used these programmes, there is always something new to learn or discover. I have used PhotoPaint for years and then I discovered the newsgroups and learnt so many new things.
I'm going to jump in and add my opinion FWIW. I think the OP suggestion is valid, however, I think maybe I would look at it a little differently. I do think that Photo-Paint could use a feature like Edit>Stroke in Photoshop. But I would not limit it to just text -- it needs to be more than that! I have often wanted to add a border around an object that is masked. Applying a brushstroke to a mask just doesn't cut it, IMO. It is never smooth, despite changing the brush settings.
Brian wrote a macro awhile back that he shared in the PP newsgroup that lets you add a pixel border (size and color your choice) around the outside of the whole image -- I would like something like that for masked/selected objects. I would also like the option to choose, outside/center/inside.
I would do it differently again:
This has the advantage that I can easily feather the edges, offset the border, use an effect as the border,...etc. Much more flexible than a static tool that only does one thing.
Alternativly I'm sure that someone could write a macro that does it for you.
