I'm using DirectX9 for rendering video output onto the screen . The library used is SlimDX.
The software created is used for marking bad pixels from the output device so it's vital that no texture filtering / smoothing is done.
I disabled all the texture filtering options , disabled anti-aliasing , and aligned the texture to the screen at 1:1 ratio between the backbuffer and the rendered texture. Thing is , on some devices , DirectX seems to be doing some bilinear filtering / blurring on the output.
I need all the output to be blocky , with -0- filtering. Since all the resize code is operated on the control itself ( no backbuffer resizing etc' ) , I don't have the option of resizing the backbuffer.
Weird thing is , this only happens on some devices , not all.
How do I tell DirectX not to smooth what it renders to the control ? ( disable whatever texture filtering is done to the back/front buffer )
Thanks in advance for any help (:
For those who do not understand what I'm trying to get rid of - when the resolution of the rendered image is lower than the resolution of the area drawn to , Direct3D creates a smooth transition between pixels. What I want is for each pixel to be drawn as a simple rectangle , with absolutely no filtering , where can I find the settings that control this behavior?
