' // Create a graphics object from the window device context DIM graphics AS CGpGraphics = hdc ' // Set the scale transform graphics.ScaleTransformForDpi

' // Set the interpolation mode

graphics.SetInterpolationMode(InterpolationModeHighQuality)

' // Get the interpolation mode DIM mode AS InterpolationMode = graphics.GetInterpolationMode

' Create font and brush DIM font AS CGpFont = CGpFont("Arial", AfxGdipPointsToPixels(16, TRUE), FontStyleRegular) DIM brush AS CGpSolidBrush = ARGB_BLACK

' // Draw text with high contrast DIM layoutRect AS GpRectF = (0, 0, 0, 0) DIM info AS WSTRING * 128 = "Interpolation mode: " & mode graphics.DrawString(info, LEN(info), @font, @layoutRect, @brush)
