Given a start and stop distance, append to dst the intervening segment(s).
[Android.Runtime.Register("getSegment", "(FFLandroid/graphics/Path;Z)Z", "GetGetSegment_FFLandroid_graphics_Path_ZHandler")]
public virtual bool GetSegment(float startD, float stopD, Android.Graphics.Path? dst, bool startWithMoveTo);[<Android.Runtime.Register("getSegment", "(FFLandroid/graphics/Path;Z)Z", "GetGetSegment_FFLandroid_graphics_Path_ZHandler")>]
abstract member GetSegment : single * single * Android.Graphics.Path * bool -> bool
override this.GetSegment : single * single * Android.Graphics.Path * bool -> boolParameters
- startD
- Single
The starting contour distance; negative values are raised to zero.
- stopD
- Single
The ending contour distance; values beyond the contour length are reduced to that length.
- dst
- Path
The path to which the extracted segment is appended.
- startWithMoveTo
- Boolean
Whether to begin the appended segment with a move to its starting point.
Returns
true when a segment is appended; false if none can be extracted, including when the adjusted start is not before the stop.
- Attributes
Remarks
Given a start and stop distance, return in dst the intervening segment(s). If the segment is zero-length, return false, else return true. startD and stopD are pinned to legal values (0..getLength()). If startD >= stopD then return false (and leave dst untouched). Begin the segment with a moveTo if startWithMoveTo is true.
On android.os.Build.VERSION_CODES#KITKAT and earlier releases, the resulting path may not display on a hardware-accelerated Canvas. A simple workaround is to add a single operation to this path, such as dst.rLineTo(0, 0).
