条形码阅读器和创建文件夹

问题描述

嗨专家，我正在开发一个名为Barcode Reader和Folder Creator的Windows应用程序，使用OnBarcode.Barcode.BarcodeScanner.dll。我想从tiff文件中读取条形码并创建相应的条形码命名文件夹。在此文件夹中，我想保存特定图像（条形码匹配页面）。除了文件夹中的特殊年龄，我已经完成了所有的工作。



请帮帮我。



[由OP更新]

我已经完成了条码阅读器和文件夹创建工作。



但我需要帮助将tiff图像拆分并保存到适当的文件夹中。



例如。在tiff文件中有8页。



Page 1有条形码：ABC101

Page 2没有条形码



第3页有条形码：ABC102

Page 4没有条形码



第5页有条形码：ABC103

Page 6无条形码



第7页有条形码：ABC104

Page 8无条形码





输出：





文件夹名称：ABC101

在此拆分页面1并保存到该文件夹​​。



文件夹名称：ABC102

在此分割中第3页并保存到该文件夹​​。



反之亦然....



我希望它的现在清楚





谢谢，

Hi Experts, I am developing a windows application called Barcode Reader and Folder Creator with the use of "OnBarcode.Barcode.BarcodeScanner.dll". I want to read the barcode from the tiff files and create corresponding barcode named folder. In this folder, I want to save the particular image (Barcode Matched page). I have done all the stuff except the Particular age in the folder.

Please help me out.

[Update by OP]
I have done the Barcode reader and folder creation stuff.

But i need help to split and save the tiff image into appropriate folder.

For eg. in the tiff file has 8 pages.

Page 1 has barcode : ABC101
Page 2 no Barcode

Page 3 has barcode: ABC102
Page 4 no Barcode

Page 5 has barcode: ABC103
Page 6 no Barcode

Page 7 has barcode: ABC104
Page 8 no Barcode


output:


Folder Name : ABC101
In this split the page 1 and save into that folder.

Folder Name : ABC102
In this split the page 3 and save into that folder.

and vice versa....

I hope its clear now


Thanks,
Murugavel S
