File Format
A BREFT sub file starts with a header of 32 bytes followed by the image data. The sub file item explained here points to this header. The size of the sub file item only counts the size of the image data.
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt32 | Unused. Offset to absolute path of intermediate file. |
| 0x04 | UInt16 | Width of the image in pixels (values in the range 0x8-0x100). |
| 0x06 | UInt16 | Height of the image in pixels (values in the range 0x10-0x100). |
| 0x08 | UInt32 | Size of image data. |
| 0x0C | Byte | Image format of the image. |
| 0x0D | Byte | Palette format of the image. |
| 0x0E | UInt16 | Number of palette entries. |
| 0x10 | UInt32 | Size of the palette data. |
| 0x14 | Byte | Total number of mipmaps. |
| 0x15 | Byte[3] | Reserved. |
| 0x18 | UInt32 | Texture data offset. |
| 0x1C | UInt32 | Palette data offset. |
