support streams or buffers about officegen HOT 9 OPEN

This works when adding images to a Powerpoint
var data = image['Data'].replace(/^data:image/\w+;base64,/, "");
var buffer = new Buffer(data, 'base64');
pptSlide.addImage(buffer,{y:yPos,cy:250,cx:250});

I'm also interested in this.

After looking into this further, it seems that addImage does support passing a stream as the first argument.

addImage will consume a node stream. This works with PowerPoint and Word.

const stream = require('stream');

function dataUrlImgStream (imgUrl) {
const splitDataUrl = /^data:.+/(.+);base64,(.*)$/;
let matches = imgUrl.match(splitDataUrl);
let data = matches[2];
let buffer = Buffer.from(data, "base64");
let bufferStream = new stream.PassThrough();
bufferStream.end(buffer);
return bufferStream;
}

pObj.addImage( dataUrlImgStream(imgUrl), {cx: 512, cy: 512});
