问题描述
我想实现一个图像编辑程序,但我不能在我的WPF显示位图。
对于一般的编辑,我需要一个位图。但我不能显示的图像。
I want to implement a image editing program, but I can not display the Bitmap in my WPF.For the general editing I need a Bitmap. But I can not display that in a Image.
private void MenuItemOpen_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog openfiledialog = new OpenFileDialog();
openfiledialog.Title = "Open Image";
openfiledialog.Filter = "Image File|*.bmp; *.gif; *.jpg; *.jpeg; *.png;";
if (openfiledialog.ShowDialog() == true)
{
image = new Bitmap(openfiledialog.FileName);
}
}
我打开了的OpenFileDialog图像到位图。现在,我想设置的画面在我的WPF。像这样:
I load the Image with a OpenFileDialog into the Bitmap. Now I want to set the picture in my WPF. Like so:
Image.Source = image;
我真的需要一个位图来获得一个特殊的像素的颜色!我需要一个简单的code剪断。
I really need a Bitmap to get the color of a special pixel! I need a simple code snipped.
谢谢您的帮助!
推荐答案
我用现在这个剪断的位图转换为ImageSource的:
I have used this snipped now to convert the Bitmap to a ImageSource:
BitmapImage BitmapToImageSource(Bitmap bitmap)
{
using (MemoryStream memory = new MemoryStream())
{
bitmap.Save(memory, System.Drawing.Imaging.ImageFormat.Bmp);
memory.Position = 0;
BitmapImage bitmapimage = new BitmapImage();
bitmapimage.BeginInit();
bitmapimage.StreamSource = memory;
bitmapimage.CacheOption = BitmapCacheOption.OnLoad;
bitmapimage.EndInit();
return bitmapimage;
}
}
