Created February 27, 2021 04:07 — forked from karlgluck/How to Access Data in the Backbuffer in Direct3D 9.cpp
This is the code for accessing pixel data from the backbuffer in a D3D9 application. Keywords: LPDIRECT3DSURFACE9 read backbuffer copy back buffer directly access back buffer Direct3D device DirectX 9
void demoExtractBackBufferPixels(LPDIRECT3DDEVICE9 d3d_device) {
// TODO: In your app, add FAILED() macros to check the HRESULTs passed back
// by each of the API calls. I leave these out for clarity.
// Grab the backbuffer from the Direct3D device
LPDIRECT3DSURFACE9 back_buffer = NULL;
d3d_device->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &back_buffer);
// Get the buffer's description and make an offscreen surface in system memory.
