GDI+错误只出现在windowsXP上-GDI+ErroronlyoccuringonwindowsXP

I have some c# code that works fine on Vista & Windows 7 but throws a GDI+ Error on Windows XP (with service pack 3 installed).

我有一些c#代码在Vista和Windows 7上运行良好，但在Windows XP上抛出GDI+错误(安装了service pack 3)。

Error thrown on XP

错误扔在XP

System.Runtime.INteropServices.ExternalException(0x80004005): A generic error occured in GDI+ at System.Drawing.Graphics.CheckErrorStatus(Int32Status) at System.Drawing.Graphics.DrawImage(Image image, Int32 x, Int32 y) At System.Drawing.Graphics.DrawImageUnscaled(Image image, Int32 x,Int 32 y) at mysolution.Core.ImageTools.ConvertToBitonal(Bitmap orginal, Int32 threshold)

System.Runtime.INteropServices.ExternalException(0x80004005): GDI+在system . draw. graphics . checkerrorstatus (Int32Status)中出现的一个通用错误。DrawImage(Image Image, Int32 x, Int32 y) At System.Drawing.Graphics。在mysolution.Core.ImageTools中，drawimageunscale(图像图像，Int32 x,Int 32 y)。ConvertToBitonal(位图原创,Int32阈值)

Code breaks on this line:

代码在这一行上中断:

using (var g = Graphics.FromImage(source))
   {
      g.DrawImageUnscaled(original, 0, 0); // Error Is Thrown Here
   }

Below is the full function I'm calling.

下面是我调用的完整函数。

    public static Bitmap ConvertToBitonal(Bitmap original, int threshold)
    {
        Bitmap source;

        // If original bitmap is not already in 32 BPP, ARGB format, then convert
        if (original.PixelFormat != PixelFormat.Format32bppArgb)
        {
            source = new Bitmap(original.Width, original.Height, PixelFormat.Format32bppArgb);
            source.SetResolution(original.HorizontalResolution, original.VerticalResolution);

            using (var g = Graphics.FromImage(source))
            {
                g.DrawImageUnscaled(original, 0, 0);
            }
        }
        else
        {
            source = original;
        }

        // Lock source bitmap in memory
        var sourceData = source.LockBits(new Rectangle(0, 0, source.Width, source.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb);

        // Copy image data to binary array
        var imageSize = sourceData.Stride * sourceData.Height;
        var sourceBuffer = new byte[imageSize];
        Marshal.Copy(sourceData.Scan0, sourceBuffer, 0, imageSize);

        // Unlock source bitmap
        source.UnlockBits(sourceData);

        // Create destination bitmap
        var destination = new Bitmap(source.Width, source.Height, PixelFormat.Format1bppIndexed);
        destination.SetResolution(original.HorizontalResolution, original.VerticalResolution);

        // Lock destination bitmap in memory
        var destinatiOnData= destination.LockBits(new Rectangle(0, 0, destination.Width, destination.Height), ImageLockMode.WriteOnly, PixelFormat.Format1bppIndexed);

        // Create destination buffer
        imageSize = destinationData.Stride * destinationData.Height;
        var destinatiOnBuffer= new byte[imageSize];

        var sourceIndex = 0;
        var destinatiOnIndex= 0;
        var pixelTotal = 0;
        byte destinatiOnValue= 0;
        var pixelValue = 128;
        var height = source.Height;
        var width = source.Width;

        // Iterate lines
        for (var y = 0; y  threshold)
                {
                    destinationValue += (byte)pixelValue;
                }
                if (pixelValue == 1)
                {
                    destinationBuffer[destinationIndex] = destinationValue;
                    destinationIndex++;
                    destinatiOnValue= 0;
                    pixelValue = 128;
                }
                else
                {
                    pixelValue >>= 1;
                }
                sourceIndex += 4;
            }

            if (pixelValue != 128)
            {
                destinationBuffer[destinationIndex] = destinationValue;
            }
        }

        // Copy binary image data to destination bitmap
        Marshal.Copy(destinationBuffer, 0, destinationData.Scan0, imageSize);

        // Unlock destination bitmap
        destination.UnlockBits(destinationData);

        // Dispose of source if not originally supplied bitmap
        if (source != original)
        {
            source.Dispose();
        }

        // Return
        return destination;
    }

Bitmap source = new Bitmap(0, 0);  
using (Graphics g = Graphics.FromImage(source))  
{   g.Clear(Color.White); 
    g.Graphics.DrawImageUnscaled(your original source,0,0);  
}
