示例

 

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

' The following example creates a solid brush and uses it to fill a rectangle. The code

' gets the color of the solid brush and stores it. Then, the code creates a second solid

' brush using the stored color and paints a second rectangle with the second solid brush.

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

SUB Example_GetColor (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)

 

  ' // Get the color of the solid brush

  DIM colour AS ARGB

  solidBrush.GetColor(@colour)

 

  ' // Create a second solid brush with that same color

  DIM solidBrush2 AS CGpSolidBrush = colour

 

  ' // Paint a second rectangle with the second solid brush

  graphics.FillRectangle(@solidBrush2, 220, 10, 200, 100)

 

END SUB
