Hi everyone!

I've searched through the forum, but found no answer on this, so I've decided to register (like "okay,okay, you got me" ), please help.

After loading image into im.manipulator and cropping it, image drops alpha and now i've got white square with my sprite instead of normal sprite, with alpha transparency.

Or maybe i can define transparency pixels again, like set alpha or something?

OMG!

It's all about bad "png" support (). I've "danced with tambourine" around "gif" and problem was solved!!!

Added:

Further research showed that the problem is in the PNG8 (that contains 256 color table so it has lesser size than any gif, bmp or so), cause PNG24 works fine.

Construct always works with PNG24 internally so I've never tried one with color tables.

Perhaps the library it uses isn't so good on those :s
