Struct TileBrushCalculator 

pub struct TileBrushCalculator { /* private fields */ }

Calculates the rectangles and transform needed to render a tile brush.

Implementations

impl TileBrushCalculator

pub fn from_brush( brush: &dyn ITileBrush, content_size: Size, target_size: Size, ) -> Self

Creates a calculator for a tile brush.

• brush - The brush to be rendered.
• content_size - The size of the content of the tile brush.
• target_size - The size of the control to which the brush is being rendered.

pub fn new( tile_mode: TileMode, stretch: Stretch, alignment_x: AlignmentX, alignment_y: AlignmentY, source_rect: RelativeRect, destination_rect: RelativeRect, content_size: Size, target_size: Size, ) -> Self

Initializes a new instance of the TileBrushCalculator type.

• tile_mode - The brush’s tile mode.
• stretch - The brush’s stretch.
• alignment_x - The brush’s horizontal alignment.
• alignment_y - The brush’s vertical alignment.
• source_rect - The brush’s source rect
• destination_rect - The brush’s destination rect.
• content_size - The size of the content of the tile brush.
• target_size - The size of the control to which the brush is being rendered.

pub fn is_valid(&self) -> bool

Upstream declares this get-only property and never assigns it, so it is always false.

pub fn destination_rect(&self) -> Rect

Gets the rectangle on the destination control to which content should be rendered.

If the tile mode of the brush is repeating then this is describes rectangle of a single repeat of the tiled content.

pub fn intermediate_clip(&self) -> Rect

Gets the clip rectangle on the intermediate image with which the brush content should be drawn when needs_intermediate is true.

pub fn intermediate_size(&self) -> Size

Gets the size of the intermediate image that should be created when needs_intermediate is true.

pub fn intermediate_transform(&self) -> Matrix

Gets the transform to be used when rendering to the intermediate image when needs_intermediate is true.

pub fn needs_intermediate(&self) -> bool

Gets a value indicating whether an intermediate image should be created in order to render the tile brush.

Intermediate images are required when a brush’s tile mode is not repeating but the source and destination aspect ratios are unequal, as all of the currently supported rendering backends do not support non-tiled image brushes.

pub fn source_rect(&self) -> Rect

Gets the area of the source content to be rendered.

pub fn calculate_translate( alignment_x: AlignmentX, alignment_y: AlignmentY, source_rect: Rect, destination_rect: Rect, scale: Vector, ) -> Vector

pub fn calculate_translate_sizes( alignment_x: AlignmentX, alignment_y: AlignmentY, source_size: Size, destination_size: Size, ) -> Vector

pub fn calculate_intermediate_transform( tile_mode: TileMode, source_rect: Rect, destination_rect: Rect, scale: Vector, translate: Vector, ) -> (Matrix, Rect)

Returns the transform and the draw rectangle (upstream’s out drawRect).
