C# Class Accord.Imaging.Filters.TexturedFilter

Textured filter - filter an image using texture.

The filter is similar to TexturedMerge filter in its nature, but instead of working with source image and overly, it uses provided filters to create images to merge (see Filter1 and Filter2 properties). In addition, it uses a bit more complex formula for calculation of destination pixel's value, which gives greater amount of flexibility:
dst = FilterLevel * ( src1 * textureValue + src2 * ( 1.0 - textureValue ) ) + PreserveLevel * src2, where src1 is value of pixel from the image produced by Filter1, src2 is value of pixel from the image produced by Filter2, dst is value of pixel in a destination image and textureValue is corresponding value from provided texture (see TextureGenerator or Texture).

It is possible to set Filter2 to . In this case original source image will be used instead of result produced by the second filter.

The filter 24 bpp color images for processing.

Sample usage #1:

// create filter TexturedFilter filter = new TexturedFilter( new CloudsTexture( ), new HueModifier( 50 ) ); // apply the filter Bitmap newImage = filter.Apply( image );

Sample usage #2:

// create filter TexturedFilter filter = new TexturedFilter( new CloudsTexture( ), new GrayscaleBT709( ), new Sepia( ) ); // apply the filter Bitmap newImage = filter.Apply( image );
