IplImage 与 CBitmap类 的相互转换
1 IplImage转换为CBitmap类型
CBitmap *IplImage2CBitmap(const IplImage *pImage)
{
if( pImage && pImage->depth == IPL_DEPTH_8U )
{
HDC hDC=GetDC(NULL);
uchar buffer[sizeof(BITMAPINFOHEADER) + 1024];
BITMAPINFO* bmi = (BITMAPINFO*)buffer;
int bmp_w = pImage->width, bmp_h = pImage->height;
FillBitmapInfo( bmi, bmp_w, bmp_h, pImage->depth*pImage->nChannels, pImage->origin );
char *pBits=NULL;
HBITMAP hBitmap=CreateDIBSection(hDC,bmi,DIB_RGB_COLORS,(void**)&pBits,NULL,0);
memcpy(pBits,pImage->imageData,pImage->imageSize);
CBitmap *pBitmap=new CBitmap;
pBitmap->Attach(hBitmap);
return pBitmap;
}
else
return NULL;
}
void FillBitmapInfo( BITMAPINFO* bmi, int width, int height, int bpp, int origin )
{
assert( bmi && width >= 0 && height >= 0 && (bpp == 8 || bpp == 24 || bpp == 32));
BITMAPINFOHEADER* bmih = &(bmi->bmiHeader);
memset( bmih, 0, sizeof(*bmih));
bmih->biSize = sizeof(BITMAPINFOHEADER);
bmih->biWidth = width;
bmih->biHeight = origin ? abs(height) : -abs(height);
bmih->biPlanes = 1;
bmih->biBitCount = (unsigned short)bpp;
bmih->biCompression = BI_RGB;
if( bpp == 8 )
{
RGBQUAD* palette = bmi->bmiColors;
int i;
for( i = 0; i < 256; i++ )
{
palette[i].rgbBlue = palette[i].rgbGreen = palette[i].rgbRed = (BYTE)i;
palette[i].rgbReserved = 0;
}
}
}
2 CBitmap转换为IplImage类型
IplImage *CBitmap2IplImage(const CBitmap *pBitmap)
{
DIBSECTION ds;
pBitmap->GetObject(sizeof(ds),&ds);
IplImage *pImage=cvCreateImage(cvSize(ds.dsBm.bmWidth,ds.dsBm.bmHeight),8,ds.dsBmih.biBitCount/8);
memcpy(pImage->imageData,ds.dsBm.bmBits,pImage->imageSize);
return pImage;
}
3.HBITMAP 转换为IplImage
IplImage* hBitmap2Ipl(HBITMAP hBmp){
}
