Struct CompositionOptions 

pub struct CompositionOptions {
    pub use_region_dirty_rect_clipping: Option<bool>,
    pub max_dirty_rects: Option<i32>,
    pub dirty_rect_merge_eagerness: Option<f64>,
    pub use_save_layer_root_clip: Option<bool>,
}

Options of the composition renderer.

Fields

use_region_dirty_rect_clipping: Option<bool>

Enables more accurate tracking of dirty rects by utilizing regions if supported by the underlying drawing context.

max_dirty_rects: Option<i32>

The maximum number of dirty rects to track when region clip is in use. Setting this to zero or a negative value removes the smarter algorithm and uses the underlying drawing context region support directly. The default value is 8.

dirty_rect_merge_eagerness: Option<f64>

Controls the eagerness of merging dirty rects. Unstable: the default is subject to change.

use_save_layer_root_clip: Option<bool>

Enforces dirty contents to be rendered into an extra intermediate surface before being applied onto the saved frame.
