SWF Scale-Nine Skin Sizing Issue
I beat my brains out over this one for 3 hours the other day. I was skinning a Flex component with a SWF library asset (a MovieClip) that used nine slice scaling. There was a visual gap between the right and bottom sides of the skinned component and its parent. For a while, I thought that this was due to some padding or something being applied to the parent.
To resolve this issue, I did two things in Flash:
1) I converted my border from lines to fills, by going to Modify > Shape > Convert Lines to Fills
2) I made sure to register the upper-left corner of the shape at 0,0.
Easy, but yet so difficult.
