Please advise a 100% working way to learn the number of pages in a PDF file.
IEGetFileFramesCount doesn't work (result is 0).

Hi

What version of ImageEn are you using? What plug-in are you using for PDF read support?

I am using 9.2.0, but can install the latest.

GhostScript. Are there other variants?

Hi

10.0.0 and newer support our new PDFium plug-in:

https://www.imageen.com/download/

You can also use WPCubed's plug-in:

Both will give much more accurate IEGetFileFramesCount. Otherwise it cannot get the frame count from compressed or encrypted files.

How to use PDFium plug-in?
Need something also besides ImageEn?
Do I need to use additional DLLs?

Since after installing the latest version, the program still does not determine the number of pages in pdf.

Hi

What is ws2def. Is that one of your units?

To use PDFium you also need to download the DLL and put it in your EXE folder:

Hi

For the next update we have changed the variable declaration of SIZE_T.
