28/// Interface for interacting with various filters. Interface is defined so that you could create
29/// Directx pipelines that involve multiple filters.
30///
31/// ## Example Usage:
32/// ```
33/// fn main () {
34///     //...
35///     let (device, context) = // acquire Device and DeviceContext
36///
37///     let input_tex = // create an input texture
38///     let output_tex = // create an output texture
39///
40///     // create some directx filter. for example the following
41///     let filter = ScaleARGBOrAYUV::new(&input_tex,&output_tex,&device);
42///
43///     // apply the filter
44///     filter.apply_filter(&context);
45///
46///     // read from the output_texture
47/// }
48/// ```
49pub trait DxFilter {
50    /// takes directx device context and applies various vertex and pixel shaders to apply the filter.
51    fn apply_filter(&self, ctx: &ID3D11DeviceContext4) -> Result<()>;
52
53    /// configure the filter to use different input texture.
54    fn set_input_tex(&mut self, tex: &Texture) -> Result<()>;
55
56    /// configure the filter to use different output texture.
57    fn set_output_tex(&mut self, tex: &Texture) -> Result<()>;
