本文實例講述了C#手工雙緩沖技巧。分享給年夜家供年夜家參考。詳細以下:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace advanced_drawing { public partial class Form19 : Form { BufferedGraphicsContext bufferContext; Bitmap gif = new Bitmap(@"d:/我的文檔/桌面/ico/a.GIF"); public Form19() { InitializeComponent(); bufferContext = new BufferedGraphicsContext(); bufferContext.MaximumBuffer = this.ClientRectangle.Size; } void gif_FrameChanged(object sender, EventArgs e) { Graphics g = this.CreateGraphics(); BufferedGraphics frame = bufferContext.Allocate(g, this.ClientRectangle); ImageAnimator.UpdateFrames(gif); frame.Graphics.DrawImage(gif, this.ClientRectangle); frame.Render(); } private void Form19_FormClosing(object sender, FormClosingEventArgs e) { bufferContext.Dispose(); } private void Form19_Paint(object sender, PaintEventArgs e) { if (ImageAnimator.CanAnimate(gif)) { ImageAnimator.Animate(gif, gif_FrameChanged); } } } }
願望本文所述對年夜家的C#法式設計有所贊助。
