<DIV>I'm got really <STRONG>crazy</STRONG>. I don't manage to use <STRONG>double buffering</STRONG> in order to <STRONG>avoid flickering</STRONG> on screen.</DIV>
<DIV> </DIV>
<DIV>I'm using <STRONG>ImageSliceViewer</STRONG> <STRONG>to render a 2D slice of my 3D image on screen</STRONG>. It works well without double buffering except for flickering on screen.</DIV>
<DIV> </DIV>
<DIV>I have already use double buffering in MFC and I have a class CMemDC that works fine to use memory buffering. </DIV>
<DIV> </DIV>
<DIV><STRONG>-> All I need is a method to get the pixel data of my 2D slice displayed on screen</STRONG>.Then I can use it to create a DIB Bitmap from what is rendered off screen. </DIV>
<DIV> </DIV>
<DIV>I found the example of rendering in MFC and I tried the series of instructions:</DIV>
<DIV> </DIV>
<DIV><STRONG>this->window->SetupMemoryRendering(x,y,hdc);</STRONG></DIV>
<DIV><STRONG>this->window->Render();</STRONG></DIV>
<DIV><STRONG>StretchBlt(dc,0,0,x,y,memDC,0,0,x,y,SRCCOPY);</STRONG></DIV>
<DIV><STRONG>this->window->ResumeScreenRendering();</STRONG></DIV>
<DIV> </DIV>
<DIV>but all is displayed is a <STRONG>white </STRONG>page. Especially because during process, <STRONG>unsigned char* MemoryData</STRONG> should be NULL.</DIV>
<DIV> </DIV>
<DIV>Please help me. </DIV>
<DIV> </DIV>
