Disable anti-alaised painting in Paint event

[Bucky]

I'm trying to resize an image and paint it in a PictureBox in its

Paint event, but the picture is supposed to be drawn regularly,

not anti-aliased. Setting the SmoothingMode property to None

has no effect; it's drawn fine, but it is still anti-aliased.

 

How can I have it painted regularly, but still scaled up?

 

Here's what I'm using ATM:

private void pic_Paint(object sender, System.Windows.Forms.PaintEventArgs e) {
Graphics g = e.Graphics;
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;

Rectangle dest = new Rectangle(xOffset * scale * -1, yOffset * scale * -1, bmp.Width * scale, bmp.Height * scale); // these are all form-level variables
g.DrawImage(bmp, dest); // bmp is a form-level variable
}

 

Thanks.

Have you tried fiddling with CompositingMode, CompositingQuality and InterpolationMode?

[Bucky]

No such luck. In fact, I just realized that I cannot even change the

properties of the Graphics object. Whenever I assign a value, the

property doesn't even change to the value I try to assign to it.

I had forgotten that e.Graphics is a read-only object.

 

So, I take it I need to do the painting somewhere else, or find a

way to alter the e.Graphics object. Which of these should I do,

and how?
