I recently searched the internet and found the control for displaying PDF files. The only one that I successfully tested was to use ActiveX functions such as Adobe Reader's acro *. dll or PDF. ocx.
However, there is a major limitation in using this, that is, the user must install Adobe Reader on the local machine. I also used this control and found that it will be attached with a lot of PDF buttons, which will undoubtedly increase the burden on the Interface display, so that we cannot display PDF files as we like.
I also found itextsharp, pdfsharp, and other controls, but I cannot find a way to implement the functions I want.
The function I want is very simple, that is, you can display the PDF file on the interface, and then add the zoom-in and zoom-out functions.
Please give a trick. Thank you!
