Function merge

pub fn merge(
    filters: impl IntoIterator<Item = Option<ImageFilter>>,
    crop_rect: impl Into<CropRect>,
) -> Option<ImageFilter>

Create a filter that merges the filters together by drawing their results in order with src-over blending.

• filters - The input filter array to merge. Any None filter pointers will use the source bitmap instead.
• crop_rect - Optional rectangle that crops all input filters and the output.
