IplImage <-> TBitMap 상호 변환 방법

IplImage -> Bitmap 로 변경시
bool __fastcall IplImageToTBitmap (const IplImage *src,Graphics::TBitmap *dest) { if (!src || !dest) return false; IplImage *temp; CvRect roi; if (src->roi) roi = cvGetImageROI(src); else roi = cvRect(0, 0, src->width, src->height); temp = cvCreateImage(cvSize(roi.width, roi.height), IPL_DEPTH_8U, 3); if (src->nChannels != 3) cvCvtColor(src,temp, CV_GRAY2RGB); else cvCopy(src,temp); if (dest->Width == 0 || dest->Height == 0) { dest->Width = roi.width; dest->Height = roi.height; } else { IplImage *temp1 = cvCloneImage(temp); cvReleaseImageData(temp); cvInitImageHeader(temp, cvSize(dest->Width,dest->Height), IPL_DEPTH_8U, 3, src->origin, 4); cvCreateImageData(temp); roi.width = dest->Width; roi.height = dest->Height; cvResize(temp1,temp); cvReleaseImage(&temp1); } dest->PixelFormat = pf24bit; try { unsigned char *pLine; int x, y; for(y = 0; y < roi.height; y++) { pLine = (unsigned char *)dest->ScanLine[roi.height - y - 1]; for(x=0 ;x <roi.width * 3 ;x++) { pLine[x]= ((unsigned char*)(temp->imageData + temp->widthStep * y))[x]; } } } catch(...) { ShowMessage("Error while converting ..."); } cvReleaseImage(&temp); return true; }
Bitmap -> IplImage 로 변경시
