Detailed Description

Structures and enumerations relating to the VTF file format.

Contains's structures and enumerations relating to the VTF file format.

Disk file format for VTF files is as follows:

• VTF Header (80 bytes)
• Low Res Image (size varies)
• Image Data (size varies)

Image Data is stored as follows:

• For each MIP images (starting with the smallest and getting larger)
  • For each frame
    • For each face (for cubemaps)
      • For each Z slice
        • Image data (in relevant format)
