Decoder for the DXT texture formats
npm install decode-dxtDecoder for the DXT texture formats.
* Supports Block Compression 1, 2 and 3 (DXT1-5)
* Works in node and in browsers with Typed Array support
An example using decode-dxt with parse-dds to decode the first mipmap texture of a DDS file using a DXT format.
``js
var decodeDXT = require('decode-dxt'),
parseDDS = require('parse-dds');
// parse the dds
var ddsBuffer = new Uint8Array(... DDS file ...),
ddsData = parseDDS(ddsBuffer);
// get the first mipmap texture
var image = ddsData.images[0],
imageWidth = image.shape[0],
imageHeight = image.shape[1],
imageDataView = new DataView(ddsBuffer.buffer, image.offset, image.length);
// convert the DXT texture to an Uint8Array containing RGBA data
var rgbaData = decodeDXT(imageDataView, imageWidth, imageHeight, ddsData.format);
``
decode(imageDataView, imageWidth, imageHeight[, format = 'dxt1'])
Decode a given DXT image to an Uint8Array containing the RGBA data of the image.
- imageDataView : A DataView pointing directly to the data of the DXT image.
- imageWidth: The width of the image.
- imageHeight: The height of the image.
- format: The format of the image (dxt1, dxt2, dxt3, dxt4 or dxt5), default to dxt1.
decode.dxt1, decode.dxt2, decode.dxt3, decode.dxt4 and decode.dxt5
