Hi,
I'm using the latest version 14.2.7 and received feedback from a customer that my tool crashes regurlarly. He uses my tool to adjust pdf parameters and it seems to happen when loading the pdf file.
Log information from my tool when the problem starts:
2025-11-20 10:50:22 OutputIMG, Load Image from R:\ttlev\in\sudoko_scale\2-easy_sol.pdf error, FileType: Adobe PDF (PDF)
I'm using the following code:
// Load IMG file
tmpIEBmp := TIEBitmap.Create;
tmpEnIO := TImageEnIO.CreateFromBitmap(tmpIEBmp);
Try
// https://www.imageen.com/help/index.php?topic=TIOParams.IPTC_Info&m=11
// Load From File
Try
// Init FileType
tmpInputfType := 'Unknown';
// Do LoadFromFile
tmpEnIO.LoadFromFile(tmpInputf, True);
tmpInputfType := tmpEnIO.Params.FileTypeStr;
// Check FileType
If Trim(tmpInputfType) = '' Then
tmpInputfType := 'Unknown';
// Aborting can also be read after loading or saving to determine if an error or abort occured
If Not tmpEnIO.Aborting Then
Begin
// Debug
tmpInfo := Format('OutputIMG, Load Image from %s successful, FileType: %s', [tmpInputf, tmpInputfType]);
UpdateLogging(0, IdLogLevInf, DefLogIMGPut, tmpInfo);
End
Else
Begin
tmpSuccess := False;
// check
tmpOSError := Winapi.Windows.GetLastError;
// Debug
If tmpOSError = 0 Then
tmpInfo := Format('OutputIMG, Load Image from %s error, FileType: %s', [tmpInputf, tmpInputfType])
Else
tmpInfo := Format('OutputIMG, Load Image from %s error: %s, FileType: %s', [tmpInputf, SysErrorMessage(tmpOSError), tmpInputfType]);
UpdateLogging(0, IdLogLevErr, DefLogIMGPut, tmpInfo);
End;
Except
On e: Exception Do
Begin
tmpSuccess := False;
// Debug
tmpInfo := Format('OutputIMG, Load Image from %s exception: %s', [tmpInputf, Trim(e.Message)]);
UpdateLogging(0, IdLogLevErr, DefLogIMGPut, tmpInfo);
End;
End;
It seems to happen in the iepdf64.dll
Any idea what I'm doing wrong?
Regards,
Pascal |

Hi Pascal
Your code looks fine. Does the issue happen randomly, or always with certain PDF files? If so, please forward or post a sample.
Also, please confirm what version of iepdf64.dll you are using:
ShowMessage( IEGlobalSettings().ImageEnVersion.Status );

Hi,
Happens randomly.
Also, please confirm what version of iepdf64.dll you are using: 140.0.7269.0 (06/07/2025 14:40)
I received the following information from the customer. He added an extra option to check if the source pdf file in still in use before loading the pdf files using LoadFromFile. Since then no crash anymore. But ImageEn should never crash even if a source file is still in use by another process, not?
Regards,
Pascal |

Hi Pascal
If the file is inaccessible or locked, then you should get an exception. What are you encountering

What are you encountering:
The application crashes, see attached image of Windows event viewer mentioning iepdf64.dll during crash. There is a Try Except End around the loadfromfile so I don't knwo what I can do extra to prevent it from crashing. |

Hmmm,
I tried to reproduce this issue by wrapping your code as follows:
procedure TForm1.Button3Click(Sender: TObject);
const
tmpInputf = 'D:\Album PDF DEMO.pdf';
var
tmpIEBmp : TIEBitmap;
tmpEnIO : TImageEnIO;
tmpInputfType, tmpInfo : string;
tmpSuccess: Boolean;
tmpOSError: Integer;
FileStream: TFileStream;
begin
FileStream := TFileStream.Create( tmpInputf, fmOpenReadWrite, fmShareExclusive);
try
// Load IMG file
tmpIEBmp := TIEBitmap.Create;
tmpEnIO := TImageEnIO.CreateFromBitmap(tmpIEBmp);
Try
// https://www.imageen.com/help/index.php?topic=TIOParams.IPTC_Info&m=11
// Load From File
Try
// Init FileType
tmpInputfType := 'Unknown';
// Do LoadFromFile
tmpEnIO.LoadFromFile(tmpInputf, True);
tmpInputfType := tmpEnIO.Params.FileTypeStr;
// Check FileType
If Trim(tmpInputfType) = '' Then
tmpInputfType := 'Unknown';
// Aborting can also be read after loading or saving to determine if an error or abort occured
If Not tmpEnIO.Aborting Then
Begin
// Debug
tmpInfo := Format('OutputIMG, Load Image from %s successful, FileType: %s', [tmpInputf, tmpInputfType]);
Caption := tmpInfo;
ImageEnView1.Assign(tmpIEBmp);
// UpdateLogging(0, IdLogLevInf, DefLogIMGPut, tmpInfo);
End
Else
Begin
tmpSuccess := False;
// check
tmpOSError := Winapi.Windows.GetLastError;
// Debug
If tmpOSError = 0 Then
tmpInfo := Format('OutputIMG, Load Image from %s error, FileType: %s', [tmpInputf, tmpInputfType])
Else
tmpInfo := Format('OutputIMG, Load Image from %s error: %s, FileType: %s', [tmpInputf, SysErrorMessage(tmpOSError), tmpInputfType]);
Caption := tmpInfo;
// UpdateLogging(0, IdLogLevErr, DefLogIMGPut, tmpInfo);
End;
Except
On e: Exception Do
Begin
tmpSuccess := False;
// Debug
tmpInfo := Format('OutputIMG, Load Image from %s exception: %s', [tmpInputf, Trim(e.Message)]);
Caption := tmpInfo;
// UpdateLogging(0, IdLogLevErr, DefLogIMGPut, tmpInfo);
End;
End;
Finally
tmpIEBmp.Free;
tmpEnIO.Free;
End;
finally
FileStream.Free;
end;
end;
As expected, it failed silently because of your try/except block. Is there more information you can give me?

| Not at the moment, I'm waiting on feedback of the customer. I'll keep you up to date. |
