示例1: decodeJpegStack
export function decodeJpegStack(data: Uint8Array, chunkDataSize: vec3, numComponents: number) {
let parser = new JpegDecoder();
parser.parse(data);
// Just check that the total number pixels matches the expected value.
if (parser.width * parser.height !== chunkDataSize[0] * chunkDataSize[1] * chunkDataSize[2]) {
throw new Error(
`JPEG data does not have the expected dimensions: ` +
`width=${parser.width}, height=${parser.height}, ` +
`chunkDataSize=${vec3.str(chunkDataSize)}`);
}
if (parser.numComponents !== numComponents) {
throw new Error(
