在vb.net中将图像文件转换为文本 [英] Converting an image file to text in vb.net

问题描述

Dim text As String = TextEdit1.Text
       Dim Height As Integer = 30
       Dim Width As Integer = 150
       Dim FileName As String = "MyImage"
       Dim objBitmap As New Bitmap(Width, Height)
       objBitmap.Save("C:\" & FileName & ".jpg", ImageFormat.Jpeg)

编写此代码是为了创建图像文件.它从文本框中读取文本，并在本地驱动器中创建一个图像文件("MyImage").

现在我想从图像中读取文本并在文本框中显示该文本.
例如，如果我在文本框中输入了Jagdish并创建了一个图像文件.
现在下一个我要从图像文件中读取文本"Jagdish"，并将其显示在文本框中.

任何人都可以帮忙找出解决方案吗?


在此先感谢
