I'm a developer currently using PDF Focus .Net in a WPF application that follows the MVVM pattern.

While working with the PdfFocus.NotifyPageProgress event and the PageProgressDelegate, I encountered a limitation when converting multiple PDF files simultaneously. Since the delegate only provides int current and int total parameters, it's difficult to distinguish which file is currently being processed when multiple conversions are running in parallel.

public delegate void PageProgressDelegate(
    int current,
    int total
)

It seems that a parameter is missing to differentiate between different files.

  • @K J However, the API documentation shows that it does provide an interface for conversion progress, but it cannot distinguish between different files. In addition, what I am describing here is not PDF reading, but conversion. Commented Sep 19 at 2:02
