问题 I am aware that pdfium exposes a javascript API (see this question). But I can't find how to call those functions. On a page with a rendered PDF I can see an embed tag, but I don't know what to do with it. var p = document.getElementsByTagName('embed')[0] Gives me this: function anonymous() __proto__: Object <function scope> And in the source code of the Chrome extension, there is this function in pdf.js: /** * Handle a scripting message from outside the extension (typically sent by *

问题 I'm trying to convert a PDF page to a .NET Bitmap using Pdfium. I want to use it directly in the WPF so WinForm methods is not intended. I already asked this question (based on my initial understanding) as I was trying to do that using FPDF_RenderPage . From what I learnt till now from SDK and the sole .NET port of it (PdfViewer) there are two ways to render to a bitmap. I want to know if I'm doing the steps correctly in first method specifically the memory device context and what is needed

I have been using Google Chrome and recently I have re-installed my browser. I found that whatever PDF links I open are directly downloading. However, I want them to be view on browser.
