it does. Please be more specific about your issue.

Desculpe @giniedp, o problema era o tamanho da imagem(3MB). Já resolvi e está funcionando como você disse.

I wrote portuguese because my english is very basic :-/

[giniedp]

yes, image size is important. everything above 2 Megapixels will be scaled down by some browsers. Spritespin tries to detect that, but the detection might fail on some PNG images, that have transparency

@giniedp I ran into an issue with a transparent png, the size was all crazy. I've set detectSubsampling:false and everything worked out.

[giniedp]

yes, subsampling detection with transparent images is not reliable. It goes wrong when border pixels or the outline of the image is transparent. There is a comment about that in the source code

spritespin/release/spritespin.js

Line 252 in ce5c8ea

// This method unfortunately does not work for images that have transparent background.

if anyone knows about a more reliable mechanism your pull reuest is welcome :)

[sebipopa]

Yes, I saw the comment, that's how I knew to disable it. Maybe a more clear explanation in the sample code (http://spritespin.ginie.eu/howto.html - Options) would help people that are getting this behavior.

Thanks for your plugin!

agree, that topic should get a section in the howto page
