Struct ktx::read::KtxDecoder

pub struct KtxDecoder<R> { /* fields omitted */ }

KTX texture storage format reader. Useful when reading from a file and/or compressed data. Provides KtxInfo.

Example

use ktx::*;
let mut decoder = ktx::Decoder::new(buf_reader)?;

assert_eq!(decoder.pixel_width(), 260);
let texture_levels: Vec<Vec<u8>> = decoder.read_textures().collect();

Methods

impl<R: Read> KtxDecoder<R>

pub fn new(data: R) -> Result<Self>

Reads KTX header data and returns a KtxDecoder.

Important traits for Textures<R>

impl<R: Read> Iterator for Textures<R> type Item = Vec<u8>;

pub fn read_textures(self) -> Textures<R>

Consumes the KtxDecoder to returns an iterator reading texture levels starting at level 0.

pub fn header(&self) -> KtxHeader

Returns KtxHeader. Useful if this info is desired after consuming the KtxDecoder.

Example

let ktx_header = decoder.header();
assert_eq!(ktx_header.pixel_width(), 260);
