Module textures 

NTF/DXT, GTT and TCT storage and native RGBA texture encoding.

Structs

TerrainColors

Square terrain colour-map collection in X-major/Z-minor order.

Texture

Editable NTF storage, preserving the original encoded pixel payload.

TextureLevel

A primary, fallback or legacy compatibility mip level.

Constants

DXT1

DXT1/BC1 fourCC in little-endian order.

DXT3

DXT3/BC2 fourCC in little-endian order.

DXT5

DXT5/BC3 fourCC in little-endian order.

Functions

append_texture

Append a validated texture to a surrounding binary record.

create_texture

Create a new NTF, including the engine’s primary and fallback level chains.

decode_level

Decode a primary/fallback mip into top-row-first RGBA, rejecting opaque legacy pixels.

encode_level

Encode RGBA with a vetted native BC compressor or explicit linear packing.

mip_size

Compute a level’s encoded size with format and dimension validation.

parse_gtt

Parse sequential GTT records from their sizes rather than pixel signature scans.

parse_tct

Parse a square TCT terrain colour-map collection.

parse_texture

Parse a named DXT file and preserve its unexplained suffix.

read_texture

Read a self-delimiting texture embedded inside another record.

write_gtt

Write a collection of unambiguously framed NTF textures.

write_tct

Write a square TCT terrain colour-map collection.

write_texture

Serialize a new or edited DXT without recompressing original payloads.
