您不需要Form双重缓冲,需要PB.在CF中很难做到这一点.但是,您可以创建自己的控件,PB非常简单.例如:
You don't need the Form double-buffered, you need the PB to be. That's not so easy to come by in CF. However, you could create your own control, PB is pretty simple. For example:
using System;
using System.Drawing;
using System.Windows.Forms;
public class MyPictureBox : Control {
private Image mImage;
public Image Image {
get { return mImage; }
set { mImage = value; Invalidate(); }
}
protected override void OnPaintBackground(PaintEventArgs pevent) {
// Do nothing
}
protected override void OnPaint(PaintEventArgs e) {
using (Bitmap bmp = new Bitmap(this.ClientSize.Width, this.ClientSize.Height)) {
using (Graphics bgr = Graphics.FromImage(bmp)) {
bgr.Clear(this.BackColor);
if (mImage != null) bgr.DrawImage(mImage, 0, 0);
}
e.Graphics.DrawImage(bmp, 0, 0);
}
base.OnPaint(e);
}
}
希望我没有使用CF中没有的东西...
Hopefully, I didn't use stuff that isn't available in CF...
