Stroke getting cut off

[kheftel-old]

Hi,

Forgive me if I missed something, but I have been playing around with Flump and noticed it sometimes cuts off part of my sprite's stroke.

I.e. here is a simple sprite in Flash:

And here is what it looks like in Flump:

You can see that a pixel or two of the bottom and right edges have been shaved off, making it not round.

This is of course just a test sprite, I'm testing Flump out to see if I can use it to enable a Flash-based vector asset-creation workflow in a Starling mobile game I'm working on.

Any help would be appreciated, thanks!

I've run into this issue in flash before when attempting to position MovieClips that have a stroke applied.

The fun part is that when you ask the Sprite/MovieClip for it's width and height it returns a value that does not include the stroke. Instead of figuring out how to get the appropriate width and height we just killed the stroke and used shapes to fake it. This is obviously not ideal, but when you don't have time to fix it, hack it, right?

I think the solution lies in asking the shape itself for it's stroke weight then padding the clip with extra space.

DisplayObject.getBounds - which we use for determining display object size in the exporter - is supposed to take stroke sizes into account, but this has been a source of frustration for me in the past as well.

We may be able to solve this issue by updating Flump's SwfTexture class to render stroked objects into a bitmap and do pixel-perfect bounds testing there. This is currently being done for objects that have filters applied to them, for similar reasons (filter-modified bounds aren't reported by Flash).

This isn't something I have the time to dive into at the moment but I'm happy to assist if you're interested in taking it on. It should be fairly straight-forward.

Yes, if stroke detection is added to SwfTexture.hasPotentiallySizeAlteringFilters(), I believe that would take care of it.

I'm also having this issue. Can anyone recommend a solution (even if temporary)?

[tconkling]

I recommended one two messages up from yours :)

To hack this in temporarily, you could try modifying SwfTexture.hasPotentiallySizeAlteringFilters to just always return true.

Is this hack implemented, also for flipbooks? Because those get cropped too with thick borders.

Not implemented currently - it should be straight-forward? I'm not able to
get to it at the moment as I'm crunching on my game.
