Hi Terrytornado,

That's a pretty good suggestion, will be stealing that :) here's the feature request: https://tracker.zkoss.org/browse/ZK-4740

You can override it, but only by overriding the whole /web/js/zkex/pdfviewer/Pdfviewer.src.js and /web/js/zkex/pdfviewer/Pdfviewer.js files in your project.

You can update here:

    _getPage: function _getPage(pageNum) {
  var _this3 = this;

  var pdfFirstRender = arguments.length > 1 && arguments[1] !== undefined ? arguments[1] : false;
  if (!this._pdf) return;

  if (this._pageRendering) {
    this._pendingPageNum = pageNum;
    return;
  }

  this._pageRendering = true;
  return this._pdf.getPage(pageNum).then(function (page) {
    var viewport = page.getViewport({
      scale: _this3._zoom,
      rotation: _this3._rotation += page._pageInfo.rotate //THIS PART ADDING THE ROTATION
    }),

I've also put in a feature request to improve on that, and allow granular overrides.

Hey there!

auto rotate is now available for PDFs that include page orientation by default :)

try it out in current FL: 9.5.1.FL.20201228(-Eval)
