要在MFC静态图片控件中显示处理后的图片,需要完成以下步骤:
1. 使用cimage类加载处理后的图片文件,例如:
```
CImage image;
image.Load(_T("processed_image.png"));
```
2. 获取静态图片控件的句柄,并将其转换为CStatic类型:
```
CStatic* pStatic = (CStatic*)GetDlgItem(IDC_STATIC_IMAGE);
```
3. 获取静态图片控件的客户区域,并创建一个兼容DC用于绘制:
```
CRect rect;
pStatic->GetClientRect(&rect);
CDC* pDC = pStatic->GetDC();
CDC memDC;
memDC.CreateCompatibleDC(pDC);
```
4. 将CImage对象渲染到兼容DC上:
```
CBitmap bitmap;
bitmap.CreateCompatibleBitmap(pDC, rect.Width(), rect.Height());
CBitmap* pOldBitmap = memDC.SelectObject(&bitmap);
image.Draw(memDC.GetSafeHdc(), rect);
```
5. 将兼容DC中的位图绘制到静态图片控件上,并释放资源:
```
pDC->BitBlt(0, 0, rect.Width(), rect.Height(), &memDC, 0, 0, SRCCOPY);
memDC.SelectObject(pOldBitmap);
pStatic->ReleaseDC(pDC);
bitmap.DeleteObject();
```
最终的代码如下:
```
CImage image;
image.Load(_T("processed_image.png"));
CStatic* pStatic = (CStatic*)GetDlgItem(IDC_STATIC_IMAGE);
CRect rect;
pStatic->GetClientRect(&rect);
CDC* pDC = pStatic->GetDC();
CDC memDC;
memDC.CreateCompatibleDC(pDC);
CBitmap bitmap;
bitmap.CreateCompatibleBitmap(pDC, rect.Width(), rect.Height());
CBitmap* pOldBitmap = memDC.SelectObject(&bitmap);
image.Draw(memDC.GetSafeHdc(), rect);
pDC->BitBlt(0, 0, rect.Width(), rect.Height(), &memDC, 0, 0, SRCCOPY);
memDC.SelectObject(pOldBitmap);
pStatic->ReleaseDC(pDC);
bitmap.DeleteObject();
```
