This is a tip that I’m sure most people who’ve used Flash will appreciate.  Try drawing a few strokes on the stage – all a pixel thick. They may look fine and dandy in the Flash IDE but try exporting the swf and prepare to be shocked. There’s a fair chance that one, some or all of your lines look blurred and fuzzy. How annoying!

Well here’s a few things you can try to ensure that your strokes remain crisp and perfect, just the way you intended.

First, check the X and Y co-ordinates of your strokes and round them up or down to a round number.

If things don’t improve go into your stroke width setting and change the number from 1 to 0.9

If thing’s still don’t improve try reducing the width of your stroke incrementally from 0.9 to 0.8, 0.7 etc.

It worked for me:

I swear that this is a genuine screen grab of the offending lines – before and after.

Good luck!
