public Form1()

InitializeComponent();
}
private void Form1_Load_1(object sender, EventArgs e)
{
// Image image = Image.FromFile(@"C:'Users'Public'Pictures'Sample Pictures'Koala.jpg");
// Set the PictureBox image property to this image.
// ... Then, adjust its height and width properties.
// pictureBox1.Image = image;
//pictureBox1.Height = image.Height;
//pictureBox1.Width = image.Width;
string strFileName = @"C:'Users'Public'Pictures'Sample Pictures'Koala.jpg";
Bitmap bitmap = new Bitmap(strFileName);
//bitmap.Save("testing.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
pictureBox1.Image = bitmap;
pictureBox1.Height = bitmap.Height;
pictureBox1.Width = bitmap.Width;
}
}
}
我正在使用上面的代码将jpg文件转换为位图。它的工作原理,但我需要知道如何流jpg图像,并将其转换为位图,然后显示位图图像与存储它。我正在使用c#和vb.net
尝试将此转换为位图:
public Bitmap ConvertToBitmap(string fileName)
{
Bitmap bitmap;
using(Stream bmpStream = System.IO.File.Open(fileName, System.IO.FileMode.Open ))
{
Image image = Image.FromStream(bmpStream);
bitmap = new Bitmap(image);
}
return bitmap;
}
可能更容易:
var bitmap = new Bitmap(Image.FromFile(path));
可能更容易:
var bitmap = new Bitmap(path);
