Thanks: 3 times

As per code in C:\LEADTOOLS 19\Examples\JS\Documents\ScanningDemo, the image viewer gets refreshed only after the scanner has stopped scanning pages.

private updatePagesView(status: lt.Scanning.JavaScript.ScanningStatus): void {
var newPageAdded: boolean = false;
for (; this._totalScannedPages < status.pageCount; this._lastPageNumber++) {
newPageAdded = true;
}

if (!status.isScanning) {
this.endOperation(false);
if (newPageAdded) {
this.gotoPage(this._lastPageNumber);
} else {
alert(status.errMessage);
}
}
}

With the above code, for example when I am scanning a batch of 5 pages, the image viewer will display only after last page in the batch is scanned.

Is there a way where we can refresh the image viewer after each page is scanned from the batch?

Any help is much appreciated.

Thanks,
Lawrence

Lawrence,

Could you provide more information on how you're running the demo? Are you using the provided web scanning service from our website?

It appears that batch scanning only obtains the image information once all pages have been scanned. Due to this, it would not be possible to update the Imageviewer with image information due to the batch process still taking place. However, I can submit a feature request to our engineering team where they will look into implementing this into future releases. Let me know if you would like to proceed with this.
