Fields

name: String

width: u32

height: u32

compression: u8

plBitmap::fCompressionType — 0=uncompressed, 1=DirectX, 2=JPEG, 3=PNG

pixel_format: u8

For DirectX: DXT type (1=DXT1, 5=DXT5). For uncompressed: pixel type.

block_size: u8

plBitmap::DirectXInfo::fBlockSize — 8 for DXT1, 16 for DXT5

pixel_size: u8

plBitmap::fPixelSize — bits per pixel (8, 16, 32)

num_levels: u8

pixel_data: Vec<u8>

Raw pixel data for all mip levels, contiguous. Level 0 at offset 0, level 1 at offset level_sizes[0], etc.

level_sizes: Vec<u32>

Size of each mip level in bytes. Translated from plMipmap::IBuildLevelSizes() in plMipmap.cpp

row_bytes: u32

plMipmap::fRowBytes — bytes per row at level 0

Implementations

impl MipmapData

pub fn decode_to_rgba(&self) -> Option<Vec<u8>>

Software-decode DXT1/DXT5 compressed texture to RGBA8 bytes. Returns None for uncompressed or unsupported formats.

pub fn from_object_data(data: &[u8], name: &str) -> Result<Self>

Parse a plMipmap from raw object data. Translated from plMipmap::Read() in plMipmap.cpp Inheritance: plMipmap : plBitmap : hsKeyedObject (NO plSynchedObject!)

pub fn from_cubic_envmap_data(data: &[u8], name: &str) -> Result<Vec<Self>>

Parse a plCubicEnvironmap and extract the first face as a regular mipmap. C++ ref: plCubicEnvironmap::Read (plCubicEnvironmap.cpp:99-110) Format: hsKeyedObject + plBitmap (outer) + 6 × plMipmap (face) Each face’s plMipmap::Read includes its own plBitmap::Read + mipmap data. Read all 6 faces from a plCubicEnvironmap. C++ ref: plCubicEnvironmap.cpp:99-110 — reads 6 plMipmap faces in order: kLeftFace=0, kRightFace=1, kFrontFace=2, kBackFace=3, kTopFace=4, kBottomFace=5

Trait Implementations

impl Clone for MipmapData

fn clone(&self) -> MipmapData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MipmapData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
