QuickReject(Path)

Return true if the specified path, after being transformed by the current matrix, would lie completely outside of the current clip.

[Android.Runtime.Register("quickReject", "(Landroid/graphics/Path;)Z", "GetQuickReject_Landroid_graphics_Path_Handler", ApiSince=30)]
public virtual bool QuickReject (Android.Graphics.Path path);

[<Android.Runtime.Register("quickReject", "(Landroid/graphics/Path;)Z", "GetQuickReject_Landroid_graphics_Path_Handler", ApiSince=30)>]
abstract member QuickReject : Android.Graphics.Path -> bool
override this.QuickReject : Android.Graphics.Path -> bool

Parameters

path: Path

The path to compare with the current clip

Returns

Boolean

true if the path (transformed by the canvas' matrix) does not intersect with the canvas' clip

Attributes: RegisterAttribute

Remarks

Return true if the specified path, after being transformed by the current matrix, would lie completely outside of the current clip. Call this to check if an area you intend to draw into is clipped out (and therefore you can skip making the draw calls). Note: for speed it may return false even if the path itself might not intersect the clip (i.e. the bounds of the path intersects, but the path does not).

QuickReject(Path, Canvas+EdgeType)

Return true if the specified rectangle, after being transformed by the current matrix, would lie completely outside of the current clip.

[Android.Runtime.Register("quickReject", "(Landroid/graphics/Path;Landroid/graphics/Canvas$EdgeType;)Z", "GetQuickReject_Landroid_graphics_Path_Landroid_graphics_Canvas_EdgeType_Handler")]

abstract member QuickReject : Android.Graphics.Path * Android.Graphics.Canvas.EdgeType -> bool
override this.QuickReject : Android.Graphics.Path * Android.Graphics.Canvas.EdgeType -> bool

Parameters

path: Path

The path to compare with the current clip

type: Canvas.EdgeType

Canvas EdgeType AA if the path should be considered antialiased, since that means it may affect a larger area (more pixels) than non-antialiased (Canvas EdgeType BW).

Boolean

true if the rect (transformed by the canvas' matrix) does not intersect with the canvas' clip
