@tgordon What were you doing to get it to load correctly? It doesnt even load correctly in the PDFJS website..
Hello dale,
Im using a Mac with Chrome, which I think might be the difference.
Unfortunately we are no longer updating our version of the PDFJS renderer, therefore we suggest you look at our sister product WebViewer that has our own in-house renderer: Free Trial: JavaScript PDF Viewer | Apryse documentation
Best regards,
Tyler
