Hello Sparrows,
my name is Andreas Loew - I am the developer of TexturePacker.
TexurePacker/Pro is a tool for MacOS which allows you to create your sprite sheets with ease. It directly writes Sparrow compatible sprite sets!
TexturePackerPro has graphical user interface with realtime update of the data.
TexturePacker (basic) is a command line tool which you can integrate into XCode for automated updates of your sprite sheets.
TexturePacker/Pro both use the same base library which comes with tons of features:
* Automated layout and sizing
* Full support for highres/lowres devices with automated resizing of assets
* Optimization for RGBA4444
* Optimized PNG output
If you got questions about it - contact me.
Cheers
Andreas
