写毕业论文要基于PCA的图像融合的代码和设计报告，可以私信发给我

private void lbl_CutImage_Paint(object sender, PaintEventArgs e)
{
int imgWidth = this.lbl_CutImage.Width - 4;
int imgHeight = this.lbl_CutImage.Height - 4;
if (imgWidth < 1) { imgWidth = 1; }
if (imgHeight < 1) { imgHeight = 1; }

// 创建缓存图像，先将要绘制的内容全部绘制到缓存中，最后再一次性绘制到 Label 上，
// 这样可以提高性能，并且可以防止屏幕闪烁的问题
Bitmap bmp_lbl = new Bitmap(this.lbl_CutImage.Width, this.lbl_CutImage.Height);
Graphics g = Graphics.FromImage(bmp_lbl);

// 将要截取的部分绘制到缓存
Rectangle destRect = new Rectangle(2, 2, imgWidth, imgHeight);
Point srcPoint = this.lbl_CutImage.Location;
srcPoint.Offset(2, 2);
Rectangle srcRect = new Rectangle(srcPoint, new System.Drawing.Size(imgWidth, imgHeight));
g.DrawImage(this.screenImage, destRect, srcRect, GraphicsUnit.Pixel);

SolidBrush brush = new SolidBrush(Color.FromArgb(10, 124, 202));
Pen pen = new Pen(brush, 1.0F);

这个50财富值搞不定
500块钱还行

你好，帮你一下保证没问题.
