See attached screenshot in regards to the pdf file

Link to a viewer (if hosted on a site other than mozilla.github.io/pdf.js or as Firefox/Chrome extension):

if (!this.contentVisible) {
      return;
    }
    const width = imgData.width;
    const height = imgData.height;
    const ctx = this.ctx;
    this.save();
    
    ctx.scale(1 / width, -1 / height);
    let imgToPaint;
    
    if (
      (typeof HTMLElement === "function" && imgData instanceof HTMLElement) ||
      !imgData.data
    ) {
      imgToPaint = imgData;
    } else {
      const tmpCanvas = this.cachedCanvases.getCanvas(
        "inlineImage",
        width,
        height
      );
      const tmpCtx = tmpCanvas.context;
      putBinaryImageData(tmpCtx, imgData, this.current.transferMaps);
      imgToPaint = tmpCanvas.canvas;
