ATF-Encoder

Pure AS3 librairies for encode/decode ATF (Adobe Texture Format) files.

require FP 11.3

Features

Decoding :

  • support all types, 2D and Cube
  • decoding sepecific face in cube texture
  • support all RGB888, RGBA8888 and Blockbased compression (decoding DXT1 version)

Encoding

  • support all types, 2D and Cube
  • support only RGB888 and RGBA8888 formats.

Utils

  • replaceImageData : modify mip/face in existing atf file
  • removeAllBut : keep only one blockbased format of existing atf file. Use it to create platform specific lightweight texture by removing unused one.
  • getSuitableBlockbasedFormat : return one of the blockbased texture formats internaly used by flash for the giver Context3D

Limitations

Encoder don't support BlockBased compression formats (DXT1, ETC1, PVRTC) due to lack of available source code :/
