JSFL SpriteSheetExporter exports png's without alpha channel.

Jul 30, 2012 4:43 AM

Hi,

 

When I generate spritesheets using the JSFL SpriteSheetExporter it seems the generated png's always come with a solid background. I have found no information in the documentation on how to control this (e.i make the background transparent).

 

SpriteSheetExporter.format returns  "RGBA8888", so the image appearenly has an alpha channel.

 

Grateful for any information or ideas to help resolve this issue.

 

Cheers!

    The transparent background is the default

     

    Maybe your Movie Clip have a solid background

    You must have exported as PNG 24, PNG 24 does not support the transparency.  PNG 8 and PNG 32  would support the transparency.

    Any update on this? I've hit the same issue. If you look at the window for "Generate Sprite Sheet" in Flash CS6, there is a "Background Color" option. No such option exists in JSFL, so all the pngs are generated with a white background, making scripting useless for any animation with transparency (all of them in my case).

    I'm having the same problem with the JSFL SpriteSheetExporter.  Nothing I've done will make alpha transparency work, so far.    Bumping so that hopefully someone who knows what's up will see this.
