位图转换为图标 [英] Converting Bitmap to Icon

问题描述

我试图将图像从一个位图转换为Windows图标。这是code。

I'm trying to convert an image from a Bitmap to a Windows icon. This is the code.

private void btnCnvrtSave_Click(object sender, EventArgs e)
{
    Bitmap bmp = (Bitmap)picturePanel.BackgroundImage;
    Bitmap newBmp = new Bitmap(bmp);
    Bitmap targetBmp = newBmp.Clone(new Rectangle(0, 0, newBmp.Width, newBmp.Height), PixelFormat.Format64bppArgb);
    IntPtr Hicon = targetBmp.GetHicon();
    Icon myIcon = Icon.FromHandle(Hicon);

    SaveFileDialog sfd = new SaveFileDialog();
    sfd.Title = "Save Icon";
    sfd.Filter = "Icon|*.ico";
    sfd.ShowDialog();

    FileStream fileStream = new FileStream(sfd.FileName,FileMode.OpenOrCreate);
    myIcon.Save(fileStream);
    fileStream.Flush();
    fileStream.Close();

    MessageBox.Show("Image is converted successfully!");
}

在code工作正常，但问题是，当我将图片转换为转换的图标失去了它的真面目和渐变的图标（图像显示）。那么，有没有任何方式，我可以将图像转换，而不会失去它的颜色？

The code is working fine but the problem is, when I convert the picture to an icon the converted icon loses its true colors and gradients (shown in image). So, is there any way by which I can convert the image without losing its colors?

这是我的图标看起来像。

This is what my icon looks like.

推荐答案

这是与.net一个已知的问题，因为它没有连接codeR的图标。请参阅可能的解决方法如下。

This is a known issue with .Net since it doesn't have an icon encoder. See the following for possible workarounds.
