我正在使用WinForms。在我的表格中,我有一个picturebox
。它的sizemode设置为Zoom
。如果我将图片加载到picturebox
,则图片会根据picturebox
尺寸进行缩放。
我想知道如何在picturebox
内获得缩放图像的大小。
这些是我尝试过的一些东西,但这并没有给我我想要的结果。
private void Debug_Write_Click(object sender, EventArgs e)
{
//var pictureWidth = pictureBox1.ClientSize.Width; //This gives the size of the picturebox
//var picturewidth1 = pictureBox1.Image.Width; This gives the actual size of the image
//var pictureHight = pictureBox1.ClientSize.Height; //This gives the size of the picturebox
//var pictureHight1 = pictureBox1.ClientSize.Height; This gives the actual size of the image
Debug.WriteLine("Width: " + pictureWidth.ToString() + " Height: " + pictureHight.ToString());
}
Picturebox
尺寸模式设置为Zoom
,因此根据我的picturebox
尺寸缩放图片:
如何找出此图像的缩放长度和宽度?
答案 0 :(得分:6)
你应该做数学!
Image img = //...;
PictureBox pb = //...;
var wfactor = (double)img.Width / pb.ClientSize.Width;
var hfactor = (double)img.Height / pb.ClientSize.Height;
var resizeFactor = Math.Max(wfactor, hfactor);
var imageSize = new Size((int)(img.Width / resizeFactor), (int)(img.Height / resizeFactor));
