getImagePixelPtr

[haha1234567]

Why did I get this result?

the imout.cpp:

void __declspec(dllexport) __stdcall imgGen(unsigned char *LVTmplImg,unsigned char tImg[380][380],unsigned char outImg[380][380],int LineWidthT,int imgWidth, int imgHeight)
{
      
     int boder;          
        unsigned char* tp = (unsigned char*)malloc(imgWidth);
       
  if(imgWidth%2!=0)
        imgWidth=imgWidth+1;
  else imgWidth=imgWidth;
     boder=(((LineWidthT-imgWidth)/2)-2)/2;
       
      
           for (int x=0; x<imgHeight;x++)
    
     {
       memcpy (tImg[x], LVTmplImg+(boder-1+x)*LineWidthT+boder, imgWidth);
     }
   
     FVLImage srcImage; 
  srcImage.New(imgWidth,imgHeight,FVLGetPixelFormat (FVLPixelFormat888));
        for(int i=0;i<imgWidth;i++)
        for (int j=0; j<imgHeight;j++)
  {
   srcImage.WritePixel(tImg[i][j],i,j);
   outImg[i][j]=(unsigned char)srcImage.ReadPixel(i,j);
  }

}

Hi

I looked over your VI and the C code. It looks like the dll resizes the image and
copy the lines in disorder. What should the code do and where is it from ?

ps: In LabVIEW it`s a delict not to wire the eeror cluster through the code

best regards
