的ImageButton，将自动调整图像 [英] ImageButton that will AutoSize the image

问题描述

我在寻找一个按钮控制将自动调整大小的形象。普通按钮控件是不会这样做的。我使用C＃.NET 2.0。

I'm searching for a button control that will AutoSize its image. Normal button controls won't do this. I'm using C#.Net 2.0.

例如，我有一个按钮，是200×50像素和图像是800 * 100像素。我要调整大小的图像，它是一个小到左边，按钮的文本附近。随着图片框我可以做到这一点。但是，当我打下了图片框在按钮的非常难看，因为你不能点击那里。

For example, I have a Button that is 200 x 50px and an image that is 800 x 100px. I want to resize the Image so that it is a little to the left, near the text of the button. With a PictureBox I can do this. But when I lay a PictureBox over the Button its very ugly because you can't click there.

推荐答案

您可以做到这一点，如下所示：

You can do this as follows:

button.Image = Image.FromFile(path);
button.AutoSize = true;

例如：或者，您可以创建一个将改变图像大小的新按钮类型：

E.g: Or, You can create a new Button type that will change the size of the image:

public class AutoSizeButton : Button
{

    public new Image Image
    {
        get { return base.Image; }
        set 
        {
            Image newImage = new Bitmap(Width, Height);
            using (Graphics g = Graphics.FromImage(newImage))
            {
                g.DrawImage(value, 0, 0, Width, Height);
            }
            base.Image = newImage;
        }
    }
}

测试：

AutoSizeButton button = new AutoSizeButton();
button.Location = new Point(27, 52);
button.Name = "button";
button.Size = new Size(75, 23);
button.Text = "Test";
button.UseVisualStyleBackColor = true;
button.Image = Image.FromFile(path);
Controls.Add(button);
