This is a small collection of programms for manipulating image data. I use it for my game SoundStorm. The source code can be accessed here.

Select image to upload:

Available operations after uploading a PNG Image:

• Split the image in 4 pieces and rearrange them. So you can glue the borders together to make infinite repeating textures.
  
• Transform a normalmap to an lighting-overlay. This can be used to make animations in Spine Animation look more plastic.
  
Please note that if multiple users use this app at the same time uploaded images can be overwritten by others. In very rare cases you will see a image from someone else manipulated instead of your own. In this case: Just try again.
