Class TSubPolygon

Properties

Unit

type TSubPolygon = class(TObject)

TSubPolygon is used to make determining whether a point is inside a TScreenObject faster.

	`constructor Create(const Points: TRealPointArray; const Count, Start: integer);`
	`destructor Destroy; override;`

	`FCount: integer;`
`FCount`: integer; `FCount` is the number of points used by the `TSubPolygon`.

	`FMaxX: real;`
`FMaxX`: real; `FMaxX` is the maximum X value of any of the points used by the `TSubPolygon`.

	`FMaxY: real;`
`FMaxY`: real; `FMaxY` is the maximum Y value of any of the points used by the `TSubPolygon`.

	`FMinY: real;`
`FMinY`: real; `FMinY` is the minimum Y value of any of the points used by the `TSubPolygon`.

	`FStart: integer;`
`FStart` is the index of the first point used by the `TSubPolygon`.

	`FSubPolygon1: TSubPolygon;`
`FSubPolygon1`: `TSubPolygon`; `FSubPolygon1` represents the `TSubPolygon` used to process the first half of the points if the number of points exceeds a threshold.

	`FSubPolygon2: TSubPolygon;`
`FSubPolygon2`: `TSubPolygon`; `FSubPolygon2` represents the `TSubPolygon` used to process the second half of the points if the number of points exceeds a threshold.

constructor Create(const Points: TRealPointArray; const Count, Start: integer);

Create creates and instance of TSubPolygon. If Count is large enough, it will create FSubPolygon1 and FSubPolygon2 to handle what it needs to do.

Points: is the array of T2DRealPoints to be used by TSubPolygon.
Count: is the number of T2DRealPoints in Points to be used by TSubPolygon.
Count: is the index of the first T2DRealPoints in Points to be used by TSubPolygon.

	`destructor Destroy; override;`
`Destroy` destroys the current instance of `TSubPolygon`. Do not call `Destroy` directly. Call Free instead.
