public BitmapImage BitmapToBitmapImage(System.Drawing.Bitmap bitmap)
{
System.Drawing.Bitmap bitmapSource = new System.Drawing.Bitmap(bitmap.Width, bitmap.Height);
int i, j;
for (i = 0; i < bitmap.Width; i++)
for (j = 0; j < bitmap.Height; j++)
{
System.Drawing.Color pixelColor = bitmap.GetPixel(i, j);
System.Drawing.Color newColor = System.Drawing.Color.FromArgb(pixelColor.R, pixelColor.G, pixelColor.B);
bitmapSource.SetPixel(i, j, newColor);
}
MemoryStream ms = new MemoryStream();
bitmapSource.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = new MemoryStream(ms.ToArray());
bitmapImage.EndInit();
return bitmapImage;
}这种方法快多了。赶紧快去试试吧：
public BitmapImage ToBitmapImage(System.Drawing.Bitmap ImageOriginal)
{
System.Drawing.Bitmap ImageOriginalBase = new System.Drawing.Bitmap(ImageOriginal);
BitmapImage bitmapImage = new BitmapImage();
using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
ImageOriginalBase.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
bitmapImage.BeginInit();
bitmapImage.StreamSource = ms;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
bitmapImage.Freeze();
}
return bitmapImage;
}补：C# Byte[]、Image、Bitmap 之间的相互转换
/// <summary>
/// 将图片Image转换成Byte[]
/// </summary>
/// <param name="Image">image对象</param>
/// <param name="imageFormat">后缀名</param>
/// <returns></returns>
public static byte[] ImageToBytes(Image Image, System.Drawing.Imaging.ImageFormat imageFormat)
{
if (Image == null) { return null; }
byte[] data = http://www.cnblogs.com/peasana/archive/2012/02/13/null;
using (MemoryStream ms= new MemoryStream())
{
using (Bitmap Bitmap = new Bitmap(Image))
{
Bitmap.Save(ms, imageFormat);
ms.Position = 0;
data = https://cache.yisu.com/upload/information/20211118/112/375749.Png);
BitmapImage bImage = new BitmapImage();
bImage.BeginInit();
bImage.StreamSource = new MemoryStream(ms.ToArray());
bImage.EndInit();
ms.Dispose();
Bi.Dispose();
System.Windows.Controls.Image i = new System.Windows.Controls.Image();
i.Source = bImage;
return i ;
}
//byte[] 转换 Bitmap
public static Bitmap BytesToBitmap(byte[] Bytes)
{
MemoryStream stream = null;
try
{
stream = new MemoryStream(Bytes);
return new Bitmap((Image)new Bitmap(stream));
}
catch (ArgumentNullException ex)
{
throw ex;
}
catch (ArgumentException ex)
{
throw ex;
}
finally
{
stream.Close();
}
}
//Bitmap转byte[]
public static byte[] BitmapToBytes(Bitmap Bitmap)
{
MemoryStream ms = null;
try
{
ms = new MemoryStream();
Bitmap.Save(ms, Bitmap.RawFormat);
byte[] byteImage = new Byte[ms.Length];
byteImage = ms.ToArray();
return byteImage;
}
catch (ArgumentNullException ex)
{
throw ex;
}
finally
{
ms.Close();
}
}
