I am new to iphone development.I am wroking on a 2D game by using cocos 2D .I am checking whether there is any software which is there for texture creating .when i searched all are paid software like texture packer, zwoptex . I am looking for free software which can be used to create texture.
TexturePacker, SpriteHelper and Zwoptex let you create texture atlases for cocos2d from individual images. They cost less than $20.
The TexturePacker trial version includes a command line version of TexturePacker that you can use for free. It has fewer features than the Pro version.
The only free alternative is Zwoptex (Flash) which is hopelessly outdated, not efficient, can only create 1024x1024 atlases and most importantly it can't update existing texture atlases automatically.
If you're looking for a free program to create images, check out Seashore and Gimp.
