通过数位板进行墨水签名 [英] ink signature through pen tablet

问题描述

我正在基于.net窗口的应用程序中工作，在该应用程序中我正在通过数位板进行墨水签名工作，我可能知道如何在数据库中保存签名，实际上我已经在其中创建了一个表单两个按钮，一个用于保存签名，另一个用于保存签名.为了清除我已通过数位板导入墨水签名的标志，进行签字的墨水签名.因此，我有一个要求，如果您在c#中有任何代码可以保存签名...请发送给我，我将非常感激您.

推荐答案

本文(含源代码)展示了如何在文件中保存/加载墨水对象:

您可以执行几乎相同的操作，但是使用ADO.NET将内容保存在数据库 blob 中.请参阅:
http://en.wikipedia.org/wiki/BLOB [ http://support.microsoft.com/kb/309158 [

This article with source code shows how to save/load ink objects in files:
http://www.c-sharpcorner.com/UploadFile/mahesh/InkPictureImages11042005153113PM/InkPictureImages.aspx[^].

You can do almost the same, but save the content in the database blob using ADO.NET. Please see:
http://en.wikipedia.org/wiki/BLOB[^],
http://support.microsoft.com/kb/309158[^].

In principle, you can also consider the option of saving the ink objects in the files with auto-generated unique names. In this case, the database can store just the file names. You will need to implement synchronization of adding/removing files in the database with the file system in transactional manner. This method is only suitable for a multi-tier architecture.
