Hi,
using the same *.exe and *.dll files on two systems and loading the same PDF document, the installation on my system (Win10 64bit) reads a barcode (symbols.size = 1) meanwhile the installation on the customer's system (WinSrv2016 64bit) fails (symbols.size = 0).
(1) On both systems, *.exe and *.dll files are located in the same folder and OnFormCreate IEVisionAvailable() results true.
(2) The PDF document is loaded in an ImageEnView1 with PdfViewer enabled and attached to an ImageEnMView1.
(3) Barcode recognition is executed in a function(PageIdx: Integer): String;
var
IEBitmap: TIEBitmap;
symbols: TIEVisionVectorObjRef;
begin
IEBitmap := TIEBitmap.Create(ImageEnMView1.GetTIEBitmap(PageIdx));
try
symbols := IEVisionLib.createBarCodeScanner().scan(IEBitmap.GetIEVisionImage(), IEVisionRect( 0, 0, 0, 0 ));
if symbols.size() > 0 then
result := TIEVisionBarCodeSymbol(symbols.getObj(symbols.size() - 1)).getData().c_str();
finally
IEBitmap.Free;
end;
end;
In order to correctly use IEVisionLib.createBarCodeScanner().scan on the customer's system, are there other files to distribute than ievision64.dll?
May somebody give me a hint where to search for the cause of the malfunction?
Thank you in advance,
Ale
