如何在socket 中实时处理图像？

Question

socket 中穿过来的图像数据包直接显示出来就是图像，可是小弟要将图像处理一下（放大）对图像怎么操作就不知道了，不知道句柄，有没有解决办法或者相关的书啊

Answer 1

关于图像显示、放大，看个例子
void CBmpView::OnDraw(CDC* pDC)
{
CAutoStitchDoc* pDoc = GetDocument();
// TODO: add draw code here
if (pDC->IsPrinting())
return;
CRect rect;
GetClientRect(&rect);
if (m_szFilename.IsEmpty()||m_hbmp==NULL)
{
// pDC->FillSolidRect(&rect,RGB(255,255,255));
return;
}
CAutoStitchApp* pApp=(CAutoStitchApp*)AfxGetApp();
m_pDC->FillSolidRect(&rect,pApp->m_backColor); CBitmap* bitmap;
CDC dc;
dc.CreateCompatibleDC(pDC);
// HBITMAP hbmp=(HBITMAP)LoadImage(NULL,m_szFilename,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
// if (hbmp==NULL)
// return;
bitmap=CBitmap::FromHandle(m_hbmp);
CBitmap* pOldBmp=dc.SelectObject(bitmap);
if (!m_bTrackMode)
{
m_pDC->BitBlt(m_topLeft.x,m_topLeft.y,m_width,m_height,&dc,0,0,SRCCOPY);
}
else
{
int width=(int)(m_width*pDoc->m_ratio*m_pGroup->m_xr);
int height=(int)(m_height*pDoc->m_ratio*m_pGroup->m_yr);
m_pDC->StretchBlt(m_topLeft.x,m_topLeft.y,width,height,&dc,0,0,m_width,m_height,SRCCOPY);
}
dc.SelectObject(pOldBmp);
pDC->BitBlt(0,0,rect.Width(),rect.Height(),m_pDC,0,0,SRCCOPY);
// DeleteObject(hbmp);
}
