I used the component TImageEnMView, where I've scanned some documents into it. Next action is to analyze the barcodes of each document. This action is only succesful at the first document. At the second document there happens an error. Must there something resetet?
some code:
m_symbols := IEVisionLib.createBarCodeScanner().scan(Bild.IEBitmap.GetIEVisionImage(), selRect);
for i := 0 to m_symbols.size() - 1 do
begin
bc := TIEVisionBarCodeSymbol( m_symbols.getObj(i) );
 data := bc.getData().c_str();
mmoBC.Lines.Add(bc.getSymbolType().c_str() + ':' + bc.getData().c_str());
The error happens at .... bc.getData().... (at the second document!)

Hi Nigel, if the last activity does not bring the desired effect in the long run I will become active again.
For now I thank you for your efforts and remain with kind regards ...

Hmmm, I've not had any other reports of that. Possibly you are leaking memory somewhere.
Can you create a small demo that reproduces the issue (e.g. with a set of images that you iterate over) and send it to me.

... OK, I should have operate not "quick reply" at the end ... just I have seen....
it seems to be so, that the memory is filling up. This message comes earlier and earlier .. after some scanning operations. I have to tell you, that I create the window at start of the programm (it remains created over the runtime). My first reaction was to rebuild the window bevor showing and destroying it at afterwards. This seems to work for now. I have not yet tried to scan a larger number of documents ... . An upload of some examples (like to be seen in the picture) is unfortunately not possible here ... I could make the file available by mail.
Some Details of the process at the end:
After scanning documents in TImageEnMView I evaluate the barcodes of each document.
When I find some defined more detailed barcodes on it I summarize all documents under it and save them in one or more pdf-files, depending on how many detailed barcodes I found.

When you click "Reply to Topic", do you have these buttons above the editor?

Hi
Are you able to provide the images and steps to reproduce the issue here?

Hi,
Concerning the barcode recognition I get now more and more often the error: "an error was encounted processing this image ...Ensure you are using the latest version of IEVision plugin". I'm now using the TIEbitmap instead of TImageENView. The Message I get is not interceptable. The process over several instances aborts.

Hi
Rather than creating a TImageEnView, can you try just using a TIEBitmap?
bmp := TIEBitmap.create();
for j := 0 to imgENvwMLSScan.ImageCount - 1 do
begin
frmLSScan.imgENvwMLSScan.CopyToIEBitmap( frmLSScan.imgENvwMLSScan.SelectedImage, bmp );
....
end;
bmp.Free();

sorry ... I forgot to mention that I choose the image naturally in ..TImageEnMView with :
frmLSScan.imgENvwMLSScan.SelectImage(j);

Hello Nigel,
sorry for answering your questions regarding my problem late (despite this i am very interested in the solution of the problem).
Yes - "Bild" is a TImageEnView.
On every Image in TImageEnMView I create a "Bild" and copy this Image to a TImageEnView
The code therefor is:
for j := 0 to imgENvwMLSScan.ImageCount - 1 do begin
Bild := TImageEnView.Create(self);
frmLSScan.imgENvwMLSScan.CopyToIEBitmap(frmLSScan.imgENvwMLSScan.SelectedImage, Bild.IO.IEBitmap);
....
The following lines are familiar to you.
....
Bild.Free;
m_symbols.clear;
end;
Thank you for your support.
Regards
S.Knoll

So is Bild a TImageEnView? What method do you use to assign the image to the TImageEnView?
Can you give us the steps (or a simple demo) to reproduce at our end?
