Q:
All the windows store sample app’s appear to be C#/XAML, are there not any JavaScript ones?
A:
With the SDK, there is a PDFDrawDemoJS project which demonstrates how to open and read a file using JavaScript.
Other than that, all the functions used in our C# samples should work in JavaScript as well.
The functions are automatically using camelCasing for JavaScript. So for example, Element.GetGState in C#, will get Element.getGState in JavaScript. That is, you should be able to create element in JavaScript exactly the same way as you do in C#.
However, the PDFViewCtrl class is not available for JavaScript, as you cannot build controls that are available for both platforms. So if you want to create a PDFViewer, you will have to use PDFDraw, or PDFRasterizer, classes and implement your own viewer experience.
Also, because JavaScript isn’t statically typed, we can not expose more than 1 function of the same name with the same number of parameters for JavaScript. We have tried to make the most universal version of a function the one available in each of these cases
