这似乎是一个 DPI 问题。首先尝试从图像初始化程序中删除宽度和高度。它还应该调整大小以适合其内容。
您还可以尝试将链接到的代码替换为以下代码,以确保正确生成图像:
using (System.Drawing.Imaging.Metafile emf = new System.Drawing.Imaging.Metafile(path))
using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(emf.Width, emf.Height))
{
bmp.SetResolution(emf.HorizontalResolution, emf.VerticalResolution);
using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bmp))
{
g.DrawImage(emf,
new Rectangle(0, 0, emf.Width, emf.Height),
new Rectangle(0, 0, emf.Width, emf.Height),
GraphicsUnit.Pixel
);
return System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(bmp.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
}
}
