## Remarks
Use the `startIndex` and `endIndex` parameters to copy a specified range of the path data.
## Examples
The following example is designed for use with Windows Forms, and it requires <xref:System.Windows.Forms.PaintEventArgs> `e`, an <xref:System.Windows.Forms.Form.OnPaint%2A> event object. The code performs the following actions:
- Creates a graphics path.
- Populates it with several primitives and some markers.
- Lists the path data on the left side of the screen.
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPathIterator> and rewinds it.
- Increments the path data index to the second marker.
- Calls the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.CopyData%2A> method to copy the path data contained between the start and end indexes to the points and types arrays.
- Lists this copied data on the right side of the screen.

## Examples
The following example is designed for use with Windows Forms, and it requires <xref:System.Windows.Forms.PaintEventArgs> `e`, an <xref:System.Windows.Forms.Form.OnPaint%2A> event object. The code performs the following actions:
- Creates a graphics path.
- Populates it with several primitives and some markers.
- Lists the path data on the left side of the screen.
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPathIterator> and rewinds it.
- Increments the path data index to the second marker.
- Calls the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.Enumerate%2A> method to copy the path data to the `points` and `types` arrays.
- Lists this copied data on the right side of the screen.

<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
All curves in a path are stored as sequences of Bézier splines. For example, when you add an ellipse to a path, you specify the upper-left corner, the width, and the height of the ellipse's bounding rectangle. Those numbers (upper-left corner, width, and height) are not stored in the path; instead; the ellipse is converted to a sequence of four Bézier splines. The path stores the endpoints and control points of those Bézier splines.
A path stores an array of data points, each of which belongs to a line or a Bézier spline. If some of the points in the array belong to Bézier splines, then <xref:System.Drawing.Drawing2D.GraphicsPathIterator.HasCurve%2A> returns `true`. If all points in the array belong to lines, then <xref:System.Drawing.Drawing2D.GraphicsPathIterator.HasCurve%2A> returns `false`.
Certain methods flatten a path, which means that all the curves in the path are converted to sequences of lines. After a path has been flattened, <xref:System.Drawing.Drawing2D.GraphicsPathIterator.HasCurve%2A> will always return `false`. Calling the <xref:System.Drawing.Drawing2D.GraphicsPath.Flatten%2A>, <xref:System.Drawing.Drawing2D.GraphicsPath.Widen%2A>, or <xref:System.Drawing.Drawing2D.GraphicsPath.Warp%2A> method of the <xref:System.Drawing.Drawing2D.GraphicsPath> class will flatten a path.
## Examples
The following example is designed for use with Windows Forms, and it requires <xref:System.Windows.Forms.PaintEventArgs> `e`, an <xref:System.Windows.Forms.Form.OnPaint%2A> event object. The code performs the following actions:
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPath> object, `myPath`.
- Adds three lines, a rectangle, and an ellipse.
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPathIterator> object for `myPath`.
- Tests to see if the current path `myPath` contains a curve.
- Shows the result of the test in a message box.

- In a `for` loop, iterates through the points using the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextPathType%2A> and <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextPathType%2A> methods.
- Uses the values returned from the iterative calls to list the subpath number, the number of points in it, and the type of the path points to the right side of the screen.
- Displays the value for the total number of points to the screen.
Note that `ListPathPoints` is a helper function that separates most (not all) of the display code from the graphics path code.

## Examples
The following example is designed for use with Windows Forms, and it requires <xref:System.Windows.Forms.PaintEventArgs> `e`, an <xref:System.Windows.Forms.Form.OnPaint%2A> event object. The code performs the following actions:
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPath> object.
- Adds three lines, a rectangle, an ellipse, and two markers.
- Lists the values of all the path's points to the left side of the screen.
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPathIterator> object.
- Creates a <xref:System.Drawing.Drawing2D.GraphicsPath> object, `myPathSection`, to receive copied points.
- Calls the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextSubpath%2A> method, which iterates to the third subpath (figure) and copies all the points contained in that subpath to the `myPathSection` path, and also returns the number of points copied to `subpathPoints`.
- Lists the subpath number and number of points it contains to the right side of the screen.

## Remarks
The first time you call the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextSubpath%2A> method of an iterator, it gets the first figure (subpath) of that iterator's associated path. The second time, it gets the second figure, and so on. When you call the <xref:System.Drawing.Drawing2D.GraphicsPathIterator.Rewind%2A> method, the sequence starts over; that is, after you call <xref:System.Drawing.Drawing2D.GraphicsPathIterator.Rewind%2A>, the next call to <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextSubpath%2A> gets the first figure in the path. The <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextMarker%2A> and <xref:System.Drawing.Drawing2D.GraphicsPathIterator.NextPathType%2A> methods behave similarly.
