Ok, im gonna describe how im doing pixel aspect ratio in windowed mode and post pics.
This envolve direct3d9. Please someone help me how to do it well.
- First i have a fuction that resizes the window to the desired client window size. Lets says SetWindowX(HWND hwnd, int x). I have tested calling after "GetClientRect()" and is resized correctly.
The body of SetWindowX() is as follow:
Are those images well point sampled and interpolated??
now i have D3D9 interface well created and "RecreateD3D()" is as follow:
"ResetD3D()" just check if it has to recreate surfaces. It free up surfaces is they are created and THEN RecreateD3D() recreates all the surfaces again. I know it could be done better but its just for starting.
The biggest thing: i use StrectchRect() D3D9 interface to "blt" between surfaces. I have one "offscreen" surface of 256x240 where pixels are put in. I know basic cards doesn't handle surfaces that are not power of 2, but my Nvidia 440 can handle as well as others nvidia and ati cards.
I use this, and is my main blitting function, that blt surfaces.
rcClip is just to crop the upper and lower 8 pixels of the image.
Now if you took a look to RecreateD3D() the Width of stage_one is multiplied by 2.
Sincerely i don't know what to do i get this:
1X:
2X:
3X:
