示例

 

' ========================================================================================

' The following example creates an AdjustableArrowCap object, myArrow, and sets the fill

' mode to TRUE. The code then creates a Pen object and assigns myArrow as the ending line

' cap for this Pen object. Next, the code tests whether myArrow is filled and, if it is,

' draws a line.

' ========================================================================================

SUB Example_IsFilled (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

  ' // Set the scale transform

  graphics.ScaleTransform(rxRatio, rxRatio)

 

  ' // Create an AdjustableArrowCap with a height of 10 pixels

  DIM myArrow AS CGpAdjustableArrowCap = CGpAdjustableArrowCap(10, 10, CTRUE)

  ' // Adjust to DPI by setting the scale width

  myArrow.SetWidthScale(rxRatio)

 

  ' // Create a Pen, and assign myArrow as the end cap

  DIM arrowPen AS CGpPen = GDIP_ARGB(255, 0, 0, 0)

  arrowPen.SetCustomEndCap(@myArrow)

 

  ' // If the cap is filled, draw a line using arrowPen

  IF myArrow.IsFilled THEN graphics.DrawLine(@arrowPen, 0, 0, 100, 100)

 

END SUB
