HEADER PARSING

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

• DDS file parse
• KTX file parse

On ERROR function will return undefined

1interface ImageInfo {
2    readonly shape: ImageShape // width and height
3    readonly layers: Array<LayerInfo> // mipmap info
4    readonly format: ImageFormat // format of image
5}

Supported parse Image formats:

• 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:

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

EXAMPLE

1import { parseDDSHeader, decodeImage } from './src'
2import * as fs from "fs"

4const buffer = fs.readFileSync('./tests/resources/dds/bc1.dds')
5const imageInfo = parseDDSHeader(buffer)
6if (imageInfo) {
7    const rgbaBuffer = decodeImage(buffer, imageInfo.format, imageInfo.layers[0])
8}

10const buffer = fs.readFileSync('./tests/resources/ktx/bc1.ktx')
11const imageInfo = parseKTXHeader(buffer)
12if (imageInfo) {
13    const rgbaBuffer = decodeImage(buffer, imageInfo.format, imageInfo.layers[0])
