◆ GetCPUColorFilterProc()

ColorFilter::ColorFilterProc impeller::LinearToSrgbColorFilter::GetCPUColorFilterProc ( ) const

Returns a function that can be used to filter unpremultiplied Impeller Colors on the CPU.

Implements impeller::ColorFilter.

◆ WrapWithGPUColorFilter()

std::shared_ptr< ColorFilterContents > impeller::LinearToSrgbColorFilter::WrapWithGPUColorFilter ( std::shared_ptr< FilterInput input,
ColorFilterContents::AbsorbOpacity  absorb_opacity 
) const
overridevirtual

Wraps the given filter input with a GPU-based filter that will perform the color operation. The given input will first be rendered to a texture and then filtered.

Note that this operation has no consideration for the original geometry mask of the filter input. And the entire input texture is treated as color information.

Implements impeller::ColorFilter.

Definition at line 137 of file color_filter.cc.

139  {
140  auto filter = ColorFilterContents::MakeSrgbToLinearFilter({std::move(input)});
141  filter->SetAbsorbOpacity(absorb_opacity);
