Member Function Documentation

Clone()

virtual std::shared_ptr<ImageFilter> impeller::ImageFilter::Clone ( ) const

pure virtual

Implemented in impeller::LocalMatrixImageFilter, impeller::ColorImageFilter, impeller::ComposeImageFilter, impeller::MatrixImageFilter, impeller::ErodeImageFilter, impeller::DilateImageFilter, and impeller::BlurImageFilter.

GetFilterContents()

std::shared_ptr< FilterContents > impeller::ImageFilter::GetFilterContents

(

)

const

Generate a new FilterContents using this filter's configuration.

    This is the same as WrapInput, except no input is set. The input
    for the filter chain can be set later using.
    FilterContents::SetLeafInputs().
