GdipAddPathArcfunction

Adds an elliptical arc to the current figure of this path.

Graphicsfunctiondocumented

Syntax

FUNCTION GdipAddPathArc (BYVAL path AS GpPath PTR, BYVAL x AS REAL, BYVAL y AS REAL, BYVAL width AS REAL, BYVAL height AS REAL, BYVAL startAngle AS REAL, BYVAL sweepAngle AS REAL) AS GpStatus

Also documented as GdipAddPathArcI — one description covers them all.

Parameters

Name		Description
`path`		[in] Pointer to the GraphicsPath object.
`x`		[in] The x-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
`y`		[in] The y-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
`width`		[in] The width of the bounding rectangle for the ellipse that contains the arc.
`height`		[in] The height of the bounding rectangle for the ellipse that contains the arc.
`startAngle`		[in] The clockwise angle, in degrees, between the horizontal axis of the ellipse and the starting point of the arc.
`sweepAngle`		[in] The clockwise angle, in degrees, between the starting point (startAngle) and the ending point of the arc.

Description

Adds an elliptical arc to the current figure of this path.

Example

' ======================================================================================== ' The following example draws a 90-degree arc. ' ======================================================================================== SUB Example_DrawArc (BYVAL hdc AS HDC)

DIM hStatus AS LONG

' // Create a graphics object from the device context DIM graphics AS GpGraphics PTR hStatus = GdipCreateFromHDC(hdc, @graphics)

' // Get the DPI scaling ratios DIM dpiX AS SINGLE hStatus = GdipGetDpiX(graphics, @dpiX) DIM rxRatio AS SINGLE = dpiX / 96 DIM dpiY AS SINGLE hStatus = GdipGetDpiY(graphics, @dpiY) Dim ryRatio AS SINGLE = dpiY / 96 ' // Set the scale transform hStatus = GdipScaleWorldTransform(graphics, rxRatio, ryRatio, MatrixOrderPrepend)

' // Create a GraphicsPath object and initializes the fill mode. DIM path AS GpPath PTR hStatus = GdipCreatePath(FillModeAlternate, @path)

' // Adds an elliptical arc to the current figure of this path.

hStatus = GdipAddPathArc(path, 140, 15, 100, 150, 0, 180) ' // Closes the current figure of the path. hStatus = GdipClosePathFigure(path)

' // Create a red pen DIM pen AS GpPen PTR hStatus = GdipCreatePen1(ARGB_RED, 1, UnitWorld, @pen) ' // Draw the path. hStatus = GdipDrawPath(graphics, pen, path)

' // Cleanup IF pen THEN GdipDeleteBrush(pen) IF path THEN GdipDeletePath(path) IF graphics THEN GdipDeleteGraphics(graphics)

END SUB ' ========================================================================================
