Could you tell me how to implement the method of "BitmapToIplImage8U"

[zeizeizhu]

please show me the implementation of the method "BitmapToIplImage8U". I has a project about twain that need to convert bmp to iplimage too. Could you tell me how to implement it.

Here is a code snippets,TEST it yourself.

IplImage* GetIplImage(Bitmap^ bitmap)
{
   Drawing::Imaging::BitmapData^ bitmapData;
   IplImage* pimg=cvCreateImage(cvSize(bitmap->Width, bitmap->Height), IPL_DEPTH_8U, 3);
   bitmapData = bitmap->LockBits(
     Drawing::Rectangle(0, 0, bitmap->Width, bitmap->Height),
     Drawing::Imaging::ImageLockMode::ReadOnly,
     Drawing::Imaging::PixelFormat::Format24bppRgb
     );
  memcpy(pimg->imageData, bitmapData->Scan0.ToPointer(), pimg->imageSize);
  pimg->imageDataOrigin = NULL;
  pimg->imageId = NULL;
  pimg->maskROI = NULL;
  pimg->roi = NULL;
  bitmap->UnlockBits(bitmapData);
  delete [] bitmapData;
  delete(bitmap);
  return pimg;
  }
}
