HEADER PARSING

Parse .DDS and .KTX files and return ImageInfo about format, mipmaps and shape of image

• [x] DDS file parse
• [X] KTX file parse

On ERROR function will return undefined

interface ImageInfo {
    readonly shape: ImageShape // width and height
    readonly layers: Array<LayerInfo> // mipmap info
    readonly format: ImageFormat // format of image
}

Supported parse Image formats:

• [x] Compressed (BC1, BC2, BC3, BC4, BC5, BC6H, BC7)
• [ ] Raw formats (RGBA, RGB, RG, R) (TODO)

DATA PARSING

Image can be decoded to RGBA Buffer layer by layer without external dependencies (only CPU usage) Supproted decode formats:

• [x] BC1
• [x] BC2
• [x] BC3
• [x] BC4
• [x] BC5
• [X] BC6H
• [X] BC7
• [ ] Raw formats - R, RG, RGB (TODO)

EXAMPLE

import { parseDDSHeader, decodeImage } from './src'
import * as fs from "fs"

const buffer = fs.readFileSync('./tests/resources/dds/bc1.dds')
const imageInfo = parseDDSHeader(buffer)
if (imageInfo) {
    const rgbaBuffer = decodeImage(buffer, imageInfo.format, imageInfo.layers[0])
}

const buffer = fs.readFileSync('./tests/resources/ktx/bc1.ktx')
const imageInfo = parseKTXHeader(buffer)
if (imageInfo) {
    const rgbaBuffer = decodeImage(buffer, imageInfo.format, imageInfo.layers[0])
}
