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)

enum VTFImageFormat

Image data formats VTFLib supports.

Image data formats supported by VTFLib. Details show colour channel order, plus number of bits per-pixel.

Note: "Bluescreen" alpha uses any pixel with an pixel of R0, G0, B255 as transparent.
