示例

 

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

' The following example creates a Font object, gets the size of the font, and creates a second

' Font object of the same size as the first. The second Font object is then used to draw text.

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

SUB Example_GetSize (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)

 

  ' // Create a Font object according to the DPI setting

  DIM font AS CGpFont = CGpFont("Arial", AfxPointsToPixelsX(16) / rxRatio)

 

  ' // Get the size of font

  DIM size AS SINGLE = font.GetSize

 

  ' // Create a second Font object with the same emSize as myFont.

  DIM sizeFont AS CGpFont = CGpFont("Arial", size)

 

  ' // Draw text using sizeFont

  DIM solidbrush AS CGpSolidBrush = GDIP_ARGB(255, 0, 0, 0)

  DIM wszText AS WSTRING * 260 = "Font with an acquired size"

  graphics.DrawString(@wszText, -1, @sizeFont, 0, 0, @solidbrush)
