GameDevelopment: Is there an equivalent to TexturePacker to optimize single images RGB format?

Question

Might be a silly question. I am using TexturePacker to export texture sheets for my Cocos2d game.

At the end of certain levels I want to display a special image that tells the user that a new world is unlocked. I thought to create a single texture sheet in pvr.ccz RGB4444 format using some useful Dithering algorithm to optimize the alpha information in the image.

However I am wondering.. is this the best way to include an optimized image in the game? Or should I use GIMP/Photoshop etc.. to optimize and export it?

Answer 1

Yes, exporting image from TexturePacker is the best (and the simplest) way. GIMP and Photoshop wont export to pvr.ccz. Even simple images generated by Photoshop or GIMP, its better to add it to TexturePacker and export again.
