如何使用secugen SDK将指纹FIR文本转换为位图？ [英] How to convert fingerprint FIR text to in bitmap using secugen SDK?

问题描述

 err = m_SecuBSP.Capture（FIRPurpose.VERIFY）
  If （err = BSPError.ERROR_NONE）然后 
 m_CaptureFIRText = m_SecuBSP.FIRTextData 
 结束 如果 
 
 DisplaySecuBSPErrMsg（  Capture，错误）
 
 
  Dim  MyHandle  As   IntPtr  = fpWindow.Handle 
 
 ' 或者从中获取图像PictureBox  
 
  Dim  MyImage  As  Image = fpWindow.Image 
 PictureBox1.Image = MyImage 
 

我尝试过：

 err = m_SecuBSP.Capture（FIRPurpose.VERIFY）
 如果（错误= BSPError.ERROR_NONE）那么 
 m_CaptureFIRText = m_SecuBSP.FIRTextData 
 结束 如果 
 
 DisplaySecuBSPErrMsg（  Capture，错误）
 
 
  Dim  MyHandle  As   IntPtr  = fpWindow.Handle 
 
 ' 或者从PictureBox获取图像 
 
  Dim  MyImage  As  Image = fpWindow.Image 
 PictureBox1.Image = MyImage 
 

解决方案

据我所知，你不能。



Th e string是打印的可识别部分的摘要，实质上，它是特征数据的散列。它不能用于重建指纹图像。



有关SDK的更多信息，您将不得不询问SecuGen支持。

err = m_SecuBSP.Capture(FIRPurpose.VERIFY)
       If (err = BSPError.ERROR_NONE) Then
           m_CaptureFIRText = m_SecuBSP.FIRTextData
       End If

       DisplaySecuBSPErrMsg("Capture", err)


       Dim MyHandle As IntPtr = fpWindow.Handle

       'Or to get the image from the PictureBox

       Dim MyImage As Image = fpWindow.Image
       PictureBox1.Image = MyImage

What I have tried:

err = m_SecuBSP.Capture(FIRPurpose.VERIFY)
      If (err = BSPError.ERROR_NONE) Then
          m_CaptureFIRText = m_SecuBSP.FIRTextData
      End If

      DisplaySecuBSPErrMsg("Capture", err)


      Dim MyHandle As IntPtr = fpWindow.Handle

      'Or to get the image from the PictureBox

      Dim MyImage As Image = fpWindow.Image
      PictureBox1.Image = MyImage

解决方案

As far as I know, you can't.

The string is a summary of the identifiable parts of the print, essentially, it's a hash of the feature data. It can't be used to rebuild an image of the fingerprint.

For further information on the SDK, you're going to have to ask SecuGen support.
