c# - Passing struct to unmanaged DLL with PInvoke -


Due to many restrictions related to the project and not specifically the problem, I have a straight one from PInvoke on C # Data related to Bitmap's MAT maker. In #C # I get a bitmap, called frame, and I'm doing this to access pixel data: 

  Bitmapdata data = frame. Lockbits (new rectangle (0,0, frame width, frame height), image lock mod.readwrit, frame pixel format); I am creating the structure for my unmanaged DLL as   
  data.Scan0  as  IntPtr . Obviously, after calling my external function, I call the  frame. Unlockbits (data);  
 
 Here the code is  C # Invoke  
 
  [DllImport ("Image Processing Experiment", Calling Convention = Calling Convention. CDCL) ] Public static extension zero directory (intimate object, referee export bitmap bitmap); Public authority (height of the public bowel); Public full width; Public IntPtr Data; Public int phase; Public INS Channel; C ++ function declaration   
  CVAPI (empty) drone (objectfender * ojjaprint, export bitmap * bitmap) {/ code>  
 Cv :: Mat testmat (CV :: size (bitmap-> width, bitmap-> height), CV_MAKETYPE (CV_8, bitmap-> channel), bitmap-> data, bitmap- & Gt; phase); }  
 
  C ++ Structure  
 
  #pragma pack (push, 8) typefif structure exportbitmap {int height; Integer width Zero * data; Int step; Int channel; } ExportBitmap; #pragma pack (pop)  
 
 So far my code seems to work until I create that mat if I modify any parameter except data from IntPtr Everything works fine. When using the Matrix Constructor Line, I get an error saying that DLL is not a valid Win32 application (error code 193 kernel 32 load library (from)) 
 
 About two solutions to me Stuck for weeks and I'm still not sure what's going on, I can only think of how I am getting editable bitmap data, but I'm not sure that the problem with it Or what could happen.
