PictureBox.Image with Interpolation and SmoothingMode

Question

The only way I know to draw an image to a picturebox without being jagged, is settings the Graphics to

    uGraphics.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
    uGraphics.SmoothingMode = Drawing2D.SmoothingMode.HighQuality

But the only way where I can do this is to do that inside a PictureBox_Paint event.

However, I would like to do it only once.

Does anybody spot where I did it wrong?

I was trying to do it like this:

PictureBoxSetImage(Me.picUserImage, Me.ILUserIcons.Images(sGUID))

Public Sub PictureBoxSetImage(ByRef uPic As PictureBox, ByRef uBMP As Bitmap)

    Using g As Graphics = Graphics.FromImage(uBMP)
        modControls.GraphicsSetSmoothingMode(g)
        uPic.Image = uBMP
    End Using

End Sub

Public Sub GraphicsSetSmoothingMode(ByRef uGraphics As Graphics)

    uGraphics.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
    uGraphics.SmoothingMode = Drawing2D.SmoothingMode.HighQuality

End Sub

With this approach, the image is still jagged. When I use the "Graphics" instead that the Paint event exposes, it works fine, and the picture is smoothed.

Can anyone help?

PictureBox does not expose these properties. To do it cleanly and [DRY](https://en.wikipedia.org/wiki/Don't_repeat_yourself), derive a class from PictureBox, override the `OnPaint` event, and add the desired properties there. — Cody Gray - on strike, Dec 16 '16 at 19:08
