well... if a pdf needs to be viewed within a browser, there is always
flex. Although, Flex it self will not support PDF (because the reader
and the flash layer live separately), there are workarounds with
either flex-iframe (http://code.google.com/p/flex-iframe/) or
flexpaper (http://flexpaper.devaldi.com/) which seem to have done a
very good job where Adobe has clearly failed.
AIR is a good alternative if you don't mind having the pdf open in a
desktop version of flex. Here's an example of a very basic pdfViewer
with AIR.
if(HTMLLoader.pdfCapability == HTMLPDFCapability.STATUS_OK){
var htmlLoader:HTMLLoader = new HTMLLoader();
var url:URLRequest = new URLRequest(pathUrl); //URL to the file
htmlLoader.width = windowWidth;
htmlLoader.height = windowHeight;
htmlLoader.load(url);
//UIComponent
var pdfViewer:UIComponent = new UIComponent();
holder.addChild(htmlLoader);
addChild(pdfViewer);
}
