Performance problems Java Barcode Scan

[vdibernardo]

Hello, I'm testing your Java barcode reader (free version ) before I purchase and I am encountering really bad performance issues. Other decoder apps can perform the same operations in sub second operations.

Test Source.
-----------------------------------------------------------------------------

Code: Select all

import com.spire.barcode.BarcodeScanner;

public class Scan {
    public static void main(String[] args) throws Exception {
        String[] s = BarcodeScanner.scan(args[0]);
        System.out.println(s[0]);

    }
}

I could send you the tiff images but I don't want to upload them to a public forum.

Thank you.

Hi,

Thanks for your files via email.
After testing your files with Spire.Barcode for Java Version:2.6.0 and the method BarcodeScanner.scan on my side, the scan times are as below:
ac3768.tif：5435ms
ac4018.tif ：5594ms
ac4024.tif：5912ms
cx1.tif：73213ms
cx2.tif：32944ms
And we suggest you add the barcode type if there is only one type barcode on image. And the cx1.tif file will cost 5918ms with the code "BarcodeScanner.scan("cx1.tif", BarCodeType.Code_128)". But for other 4 files, there is no obvious improvement. I have logged the time performance issue in our bug tracking system with the ticket SPIREBARCODE-139.
And I also noticed we only scanned the barcode on the first page of the file cx1.tif and cx2.tif. I have also posted this issue to our Dev team with the ticket SPIREBARCODE-140.
Once there is any update regarding the two issues, we will let you know.

Sincerely,
Betsy
