CGpGraphicsPathIterator.GetCountmethod

Returns the number of data points in the path.

Syntax

FUNCTION GetCount () AS INT

Description

Returns the number of data points in the path.

Remarks

This GraphicsPathIterator object is associated with a GraphicsPath object. That GraphicsPath object has an array of points and an array of types. Each element in the array of types is a byte that specifies the point type and a set of flags for the corresponding element in the array of points. Possible point types and flags are listed in the PathPointType enumeration.

Example

' ======================================================================================== ' Returns the number of data points in the path. ' ======================================================================================== SUB Example_PathIterGetCount (BYVAL hdc AS HDC)

' // Create a graphics object from the window device context DIM graphics AS CGpGraphics = hdc ' // Set the scale transform graphics.ScaleTransformForDpi

' // Create a GraphicsPath with two figures DIM path AS CGpGraphicsPath path.AddLine(20, 20, 120, 20) path.AddLine(120, 20, 70, 100) path.CloseFigure

path.StartFigure path.AddLine(150, 30, 200, 80) path.AddLine(200, 80, 150, 130)

' // Create a GraphicsPathIterator DIM iterator AS CGpGraphicsPathIterator = CGpGraphicsPathIterator(@path)

' // Get total number of points in the path DIM totalCount AS LONG = iterator.GetCount()

' // Create font and brush for displaying the result DIM fontFamily AS CGpFontFamily = CGpFontFamily("Arial") DIM font AS CGpFont = CGpFont(@fontFamily, AfxGdipPointsToPixels(16, TRUE), FontStyleRegular) DIM brush AS CGpSolidBrush = ARGB_BLACK

' // Draw the total point count as a string DIM info AS STRING = "Total path points: " & totalCount DIM layout AS GpRectF = (10.0, 10.0, 300.0, 20.0) graphics.DrawString(info, -1, @font, @layout, @brush)
