TM

• Format type: Image
• Endianness: Little-endian

Format Specifications

char {4}     - identifier ("BIFF")

uint32 {4}   - format version (1 or 2 allowed)
uint32 {4}   - Unknown
uint32 {4}   - Unknown
uint32 {4}   - number of chunks
// for each chunk

uint32 {4}   - begin marker (0xf0f0f0f0)

uint32 {4}   - data type

uint32 {4}   - Unknown

uint32 {4}   - data size

// if format version is 2

uint32 {4}   - Unknown

// if data type is 0x02faf082 (palette)

uint32 {4}   - number of palette colours

// for each colour

uint16 {2}   - red colour value

uint16 {2}   - green colour value

uint16 {2}   - blue colour value

// if data type is 0x02faf080 (image)

uint16 {2}   - name length

char {x}     - name (zero-terminated)

byte {1}     - Unknown

uint32 {4}   - image width

uint32 {4}   - image height

uint32 {4}   - number of MIP map levels

// for each MIP map level

byte {x}     - palettised image data (dimensions are halved after each level)

// if data type is something else

byte {x}     - Unknown (never encountered)

uint32 {4}   - end marker (0x0f0f0f0f)

uint32 {4}   - number of subchunks

// for each subchunk

(chunks can be arbitrarily nested, the same format rules apply)

Notes and Comments

TM files contain textures in (optionally) various MIP map levels. The same chunk layout is used for BIFF files as well, though the data types encountered in those files are usually different.
