示例
' ========================================================================================
' The following example creates a solid brush and uses it to fill a rectangle. The code
' uses GdipSetSolidFillColor to change the color of the solid brush and then paints a
' second rectangle the new color.
' ========================================================================================
SUB Example_SetColor (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 a solid brush, and use it to fill a rectangle
DIM solidBrush AS CGpSolidBrush = GDIP_ARGB(255, 0, 0, 255)
graphics.FillRectangle(@solidBrush, 10, 10, 200, 100)
' // Change the color of the brush to red, and fill another rectangle
solidBrush.SetColor(GDIP_ARGB(255, 255, 0, 0))
graphics.FillRectangle(@solidBrush, 220, 10, 200, 100)
END SUB
