问题
I am looking into putting together a small site that reads a few PDF files and loads them in the PDF.js viewer. (I want to use the viewer specifically) I still want all of the viewer UI and functionality present, just adding a sidebar with a list of files to chose from.
Alas I have not been able to really understand the PDF.js code (or a lot of the Viewer.js code provided for that matter)
Currently I am looking for a way to pass the PDF.js viewer a new file to open. (Without reloading the page and using the url parameter)
With that said that is only the bare minimum functionality to continue with this project.
I am also looking for something that can resemble a function reference for any of the Viewer / PDF.js functions that can be used for interactions:
- I/O of the files
- moving through pages / headings
- scaling the pdf
- any event triggers
I haven't been able to find anything direct from Mozzila's Github Wiki. And the recent tutorials that I have been able to find don't make use of the Viewer at all.
回答1:
To open a file from a url: PDFView.open(url, 0);
Set page: PDFView.page = 2;
zoom/scale: PDFView.zoomIn(10); PDFView.zoomOut(10);
Basically just look at the PDFView object in viewer.js.
