Greetings,

Delphi XE5
ImageEn 5.0.5

I thought from reading the help file that I could use TImageEnIO.ParamsFromFile to fetch the page count in a tiff file without having to open it, but it returns 0. What am I doing wrong?

var
ImageInfo: TImageEnIO;
iPageCnt: SmallInt;
begin
TRY
//* Fetch the page count for this tiff without actually loading the file
ImageInfo := TImageEnIO.Create(Self);
ImageInfo.ParamsFromFile(FileName);
iPageCnt := ImageInfo.Params.TIFF_PageCount;

FINALLY
END
end

If all you need is the page count try IO.IEGetFileFramesCount...

function IEGetFileFramesCount(const FileName: WideString): Integer;

Description
A generic method to get the number of frames in a multi-page images and supported videos (GIF, TIFF, AVI, MPEG...).

Thanks Bill,

When attempting to try your suggestion I found that it was a function in imageenio not io. 

iPageCnt := imageenio.IEGetFileFramesCount(FileName);


All is well it works great.
