Syntax

FUNCTION DrawArc (BYVAL pPen AS CGpPen PTR, BYVAL x AS SINGLE, BYVAL y AS SINGLE, BYVAL nWidth AS SINGLE, BYVAL nHeight AS SINGLE, BYVAL startAngle AS SINGLE, BYVAL sweepAngle AS SINGLE) AS LONG

FUNCTION DrawArc (BYVAL pPen AS CGpPen PTR, BYVAL x AS INT_, BYVAL y AS INT_, BYVAL nWidth AS INT_, BYVAL nHeight AS INT_, BYVAL startAngle AS SINGLE, BYVAL sweepAngle AS SINGLE) AS LONG

FUNCTION DrawArc (BYVAL pPen AS CGpPen PTR, BYVAL rc AS GpRectF PTR, BYVAL startAngle AS SINGLE, BYVAL sweepAngle AS SINGLE) AS LONG

FUNCTION DrawArc (BYVAL pPen AS CGpPen PTR, BYVAL rc AS GpRect PTR, BYVAL startAngle AS SINGLE, BYVAL sweepAngle AS SINGLE) AS LONG

Parameters

Name		Description
`pPen`		Pointer to a pen that is used to draw the arc.
`x`		The x-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
`y`		The y-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
`nWidth`		The width of the ellipse that contains the arc.
`nHeight`		The height of the ellipse that contains the arc.
`startAngle`		The angle between the x-axis and the starting point of the arc.
`sweepAngle`		The angle between the starting and ending points of the arc.

Return value

If the function succeeds, it returns StatusOk, which is an element of the GpStatus enumeration.

If the function fails, it returns one of the other elements of the GpStatus enumeration.

Description

Draws an arc. The arc is part of an ellipse.

Example

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

' // Create a graphics object from the window device context DIM graphics AS CGpGraphics = hdc ' // Get the DPI scaling ratio DIM rxRatio AS SINGLE = graphics.GetDpiX / 96 DIM ryRatio AS SINGLE = graphics.GetDpiY / 96 ' // Set the scale transform graphics.ScaleTransform(rxRatio, ryRatio)

' // Draw the arc DIM redPen AS CGpPen = CGpPen(ARGB_RED, 3) graphics.DrawArc(@redPen, 0, 0, 200, 100, 0.0, 90.0)
