Subject: Re: How do I find all the barcodes in an image?
In reply to: David Weisbrod 's message, "How do I find all the barcodes in an image?" on 14:22:24 05/14/03 Wed

Following your requirement I have developed a component allowing to find barcodes over an image: TBarCodesFinder.

Here a sample usage:

procedure TForm1.FindBarcodes1Click(Sender: TObject);
Var BCFinder:TBarCodesFinder;
i:integer;
begin
BCFinder:=TBarCodesFinder.Create;
try
// Find the barcodes
if BCFinder.Find(ImageScrollBox1.Graphic) then
begin
// Iter by all found barcodes
For i:=0 to BCFinder.BarCodesCount-1 do
// Do something with each barcode area... eg recognize it !
DoSomething(BCFinder.BarCode[i])
end;
finally
BCFinder.Free;
end;
end;

You can set several paremeters to make a fine tuning on your images type.

The component will be available in next days as shareware on my web site: <a rel=nofollow target=_blank href="http://web.tiscalinet.it/delphipage">http://web.tiscalinet.it/delphipage</a>
