If the PDF is embedded by ordinary HTML (= set url of the browser widget or use in its htmlText <embed>, <iframe> or <object>) then you can't decide for the user which plugin to use.
But the user can force this for himself by moving the corresponding plugin(s) in/out of the plugins-folder (which is on Mac "/Library/Internet Plug-ins"). Controlling is fully possible because the user cannot disable JavaScript for the browser widget. So you can use the rendering library "pdf.js": https://mozilla.github.io/pdf.js/ (which drives the Firefox and Opera PDF-viewer). This isn't easy to implement if CORS isn't available, but you can use base64-encoded data URLs without problems. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
