Syntax

FUNCTION GdipAddPathLine (BYVAL path AS GpPath PTR, BYVAL x1 AS REAL, BYVAL y1 AS REAL, BYVAL x2 AS REAL, BYVAL y2 AS REAL) AS GpStatus

Also documented as GdipAddPathLineI — one description covers them all.

Parameters

Name		Description
`path`		[in] Pointer to the GraphicsPath object.
`x1`		[in] The x-coordinate of the starting point of the line.
`y1`		[in] The y-coordinate of the starting point of the line.
`x2`		[in] The x-coordinate of the ending point of the line.
`y2`		[in] The y-coordinate of the ending point of the line.

Description

Adds a line to the current figure of the path.

Example

' ======================================================================================== ' This example draws a single line using GdipAddPathLine. ' ======================================================================================== SUB Example_DrawLine (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)

' // Add a line from (50, 50) to (250, 150) hStatus = GdipAddPathLine(path, 50, 50, 250, 150)

' // Create pen DIM pen AS GpPen PTR hStatus = GdipCreatePen1(ARGB_BLACK, 2, UnitWorld, @pen)

' // Draw path hStatus = GdipDrawPath(graphics, pen, path)

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

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