Re: How to correct upside down image?

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

To capture the DX9 screen I first created an OffscreenPlainSurface
and then called GetRenderTargetData to put the data in a buffer.
D3DSURFACE_DESC VDesc;

vidGen::vidGen() //constructor for the video generator

{

//Get front buffer screen size

LstErr= g_pd3dDevice->GetRenderTarget( 0, &ppRenderTarget);

LstErr= ppRenderTarget->GetDesc(&VDesc);

//create the surface to store the captured bitmaps

LstErr= g_pd3dDevice->CreateOffscreenPlainSurface(

VDesc.Width, VDesc.Height, VDesc.Format, D3DPOOL_SYSTEMMEM, &pBuf, NULL);

} //vidGen

After locking the buffer I called avi.AppendNewFrame.

Attempting to change the sign of Desc.Height during this process
was not well received since it is typed as unsigned.

So where do I change it?

Thanks Rhett for all your effort on this,
E-Jo
