import { ALPHA_MODES } from '@pixi/constants'; /** * Helper for detecting the correct alpha mode for video textures. * For some reason, some browsers/devices/WebGL implementations premultiply the alpha * of a video before and then a second time if `UNPACK_PREMULTIPLY_ALPHA_WEBGL` * is true. So the video is premultiplied twice if the alpha mode is `UNPACK`. * In this case we need the alpha mode to be `PMA`. This function detects * the upload behavior by uploading a white 2x2 webm with 50% alpha * without `UNPACK_PREMULTIPLY_ALPHA_WEBGL` and then checking whether * the uploaded pixels are premultiplied. * @memberof PIXI.utils * @function detectVideoAlphaMode * @returns {Promise<PIXI.ALPHA_MODES>} The correct alpha mode for video textures. */ export declare function detectVideoAlphaMode(): Promise<ALPHA_MODES>;
