DotSpatial.Data.Extent

Extent

Summary

Extent works like an envelope but is faster acting, has a minimum memory profile, only works in 2D and has no events.

Methods

	Name	Description
	Clone	Produces a clone, rather than using this same object.
	Constructor	This function has 5 overloads.
	Contains	This function has 3 overloads.
	CopyFrom	Copies the MinX, MaxX, MinY, MaxY values from extent.
	Equals	Allows equality testing for extents that is derived on the extent itself.
	ExpandBy	This function has 2 overloads.
	ExpandToInclude	This function has 2 overloads.
	GetHashCode	Spreads the values for the basic X, Y extents across the whole range of int. Repetition will occur, but it should be rare.
	Intersection	Calculates the intersection of this extent and the other extent. A result with a min greater than the max in either direction is considered invalid and represents no intersection.
	Intersects	This function has 5 overloads.
	IsEmpty	If this is undefined, it will have a min that is larger than the max, or else any value is NaN. This only applies to the X and Z terms. Check HasM or HasZ higher dimensions.
	Parse	This allows parsing the X and Y values from a string version of the extent as: 'X[-180|180], Y[-90|90]' Where minimum always precedes maximum. The correct M or MZ version of extent will be returned if the string has those values.
	SetCenter	This function has 3 overloads.
	ToEnvelope	Creates a geometric envelope interface from this
	ToString	Creates a string that shows the extent.
	TryExtract	Attempts to extract the min and max from one element of text. The element should be formatted like X[1.5, 2.7] using an invariant culture.
	TryParse	This reads the string and attempts to derive values from the text.
	TryParseExtremes	This method converts the X and Y text into two doubles.
	Within	This function has 2 overloads.

Properties

	Name	Description
	HasM	Gets or sets whether the M values are used. M values are considered optional,and not mandatory. Unused could mean either bound is NaN for some reason, orelse that the bounds are invalid by the Min being less than the Max.
	HasZ	Gets or sets whether the M values are used. M values are considered optional,and not mandatory. Unused could mean either bound is NaN for some reason, orelse that the bounds are invalid by the Min being less than the Max.
	Height	Gets MaxY - MinY. Setting this will update MinY, keeping MaxY the same. (Pinned at top left corner).
	MaxX	Max X
	MaxY	Max Y
	MinX	Min X
	MinY	Min Y
	Width	Gets MaxX - MinX. Setting this will update MaxX, keeping MinX the same. (Pinned at top left corner).
	X	Gets MinX. Setting this will shift both MinX and MaxX, keeping the width the same.
	Y	Gets MaxY. Setting this will shift both MinY and MaxY, keeping the height the same.
