我需要我的缩放图像在C＃中别名-IneedmyscaledimagetobealiasedinC#

This might be an odd question, but when I scale my image in C# I need it to be pixelated and not anti-aliased. Just like in MSpaint when you scale.

这可能是一个奇怪的问题,但是当我在C#中扩展我的图像时,我需要将其设置为像素化而不是消除锯齿。就像在缩放时的MSpaint一样。

I hope images anti-alias by default in C#, or else I changed something I didn't want to.

我希望在C#中默认图像反别名,否则我改变了我不想要的东西。

I've tried playing around with the Graphics.InterpolationMode but no luck there. I'm using a Bitmap object to hold the image and it's being constructed like so:

我试过玩Graphics.InterpolationMode但没有运气。我正在使用Bitmap对象来保存图像,它的构造如下:

// A custom control holds the image
this.m_ZoomPanPicBox.Image = new Bitmap(szImagePath);

And a brief synapsis of the custom control:

以及自定义控件的简要概述:

class ZoomPanPicBox : ScrollableControl
{
    Image m_image;
    float m_zoom = 1.0f;
    InterpolationMode m_interpolationMode;
    ...
    ////////////////////////////////////////////////////////
    public ZoomPanPicBox()
    {
        //Double buffer the control
        this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.ResizeRedraw | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true);

        this.AutoScroll=true;
    }
    ////////////////////////////////////////////////////////
    protected override void OnPaint(PaintEventArgs e)
    {
        //if no image, don't bother
        if(m_image==null)
        {
            base.OnPaintBackground(e);
            return;
        }

        //Set up a zoom matrix
        Matrix mx = new Matrix(m_zoom,0,0,m_zoom,0,0);

        //now translate the matrix into position for the scrollbars
        mx.Translate(this.AutoScrollPosition.X / m_zoom, this.AutoScrollPosition.Y / m_zoom);

        //use the transform
        e.Graphics.Transform = mx;

        //and the desired interpolation mode
        e.Graphics.InterpolatiOnMode= m_interpolationMode;

        //Draw the image ignoring the images resolution settings.
        e.Graphics.DrawImage(m_image,new Rectangle(0,0,this.m_image.Width,this.m_image.Height),0,0,m_image.Width, m_image.Height,GraphicsUnit.Pixel);

        base.OnPaint(e);
    }

Any ideas? Thanks.
