Importing Flash Art

[Redsquirrel]

I did a animation on flash yesterday and have extracted as PNG. However, its still doing the white outlines.

Ive included a picture of the issue to give people an idea..

I thought i had somewhat fixed the issue but apparently not.

That`s the almighty halo. You turned a alphachanneled image into a image with one transparent colour here. The borderpixels at an alphachanneled image are not just one colour though. But a mix between the background colour and the colour in the border of the sprite. And so this pixels gets ignored then.

Some software turns the background colour to white when it becomes transparent with alphachannel. Known issue for Photoshop for example. And that`s where you get a white halo then.

Some software can compensate the halo by premultiplied alpha. MMF is not this advanced. Its image editor sucks at more than one end. And it would fail at conversion from Alphachanneled to Transparent colour anyways. And so you have to fix it manually.

You could for example open the image with alphachannel in your graphics software, remove the alpha channel there, and take care that the colour in the hidden

I´ve made a tool some times ago that removes the halo from alphachanneled images by extending the borderpixels of the visible sprite. Maybe it`s helpful for you too.

Thanks Ill be sure to give it a shot..

edit: I did give it a go, although no joy..

Going to try a couple things when i get home (some setting when exporting PNG in flash).

I've been a bit of a idiot..

I neglected the fact I was switching between MMF and the newgrounds free TGF.

The problem being that it turns out TGF doesnt support alpha channels. when i tried the exact thing out in MMF it works fine.

bit of a shame wanted to test out stuff in flash first, i know ill probably end up getting the flash export at some point though.

That Explains Everything, lol.
Yeah, I never thought to ask if your importing it into anything other than MMF2. Glad you found the problem tho.

try save the images as .bmp import into newgrounds TGF.
