有装msdn没

没有去www.msdn.com

查找Graphics类

然后你就搞定了

public void DrawImage4Float(PaintEventArgs e)
{

// Create image.
Image newImage = Image.FromFile("SampImag.jpg");

// Create coordinates for upper-left corner.

// of image and for size of image.
float x = 100.0F;
float y = 100.0F;
float width = 450.0F; 指定大小
float height = 150.0F;

// Draw image to screen.
e.Graphics.DrawImage(newImage, x, y, width, height);
}
