Texture Entry

Entry Texture Types

All shape entries start with a header that looks like this:

struct ShapeChunkHeader {
    uint8_t chunkType;
    uint24_t nextChunk;
    // Note that the above isn't a standard type.
    // You can probably represent it as a bitfield if you want.

    // In layman's terms, if the next chunk offset is 0, then
    // it's the end of this shape.
    bool IsEndOfShape() {
         return nextChunk == 0;
    }
};


Chunk Type	Description
0x1	4-Bit (16 Colours) Data
0x2	8-bit (256 Colours) Data
0x5	32-bit True Color Image
0x20	Palette/CLUT
105	Metal Bin (Metal Alpha)
0x70	Long/Full Name
0x85 (`0x5 OR 0x80`)	8-bit Data, RefPack Compressed

If `(type & 0x80) == 1` (seemingly only used for image data) the data is compressed with RefPack.

Texture Header


Type	Description
Byte	Entry Type
UInt24	Size
UInt16	Width
UInt16	Height
UInt16	XAxis
UInt16	YAxis
UInt16	Swizzled
UInt16	Unknown

The data following this header can be:


Image Type	Data Type
4-bit	4-bit indexes into Palette/CLUT
8-bit	8-bit indexes into Palette/CLUT
32-bit	BGRA8888 Direct Colors

Colour Palette Header

(this is the same as the image header, it's just [color count] x 1 sized)


Type	Description
Byte	Entry Type
UInt24	Size
UInt16	Width
UInt16	Height
UInt16	Total
UInt16	Unknown
UInt16	Swizzled
UInt16	Unknown

After the header is *Width* count BGRA8888 colors used to make up the palette.

Long Name Header


Type	Description
Byte	Entry Type
UInt24	Size
C String	Long Name
