WPF中将指纹字节数组转换为ImageSource的过程可以通过以下步骤完成: 首先,需要将指纹字节数组转换为Bitmap对象。可以使用System.Drawing命名空间中的类来实现这一步骤。具体代码如下: 代码语言:txt 复制 using System.Drawing; using System.IO; // 将指纹字节数组转换为Bitmap对象 public Bitmap ByteArrayToBitmap(byt...
BitmapImage转换为byte[]: publicstaticbyte[] BitmapImageToByteArray(BitmapImage bmp) {byte[] byteArray =null;try{ Stream sMarket=bmp.StreamSource;if(sMarket !=null&& sMarket.Length >0) {//很重要,因为Position经常位于Stream的末尾,导致下面读取到的长度为0。sMarket.Position =0;using(BinaryReade...
bmp.StreamSource =newMemoryStream(stream.ToArray());//stream;bmp.EndInit(); bmp.Freeze(); }returnbmp; }// RenderTargetBitmap --> BitmapImagepublicstaticBitmapImageRenderTargetBitmapToBitmapImage(RenderTargetBitmap rtb){varrenderTargetBitmap = rtb;varbitmapImage =newBitmapImage();varbitmap...

UserHeadImage.Source = null; 注意 如果StreamSource 和 UriSource 均设置,则忽略 StreamSource 值。要在创建 BitmapImage 后关闭流,请将 CacheOption 属性设置为 BitmapCacheOption.OnLoad。默认 OnDemand 缓存选项保留对流的访问,直至需要位图并且垃圾回收器执行清理为止。 下面的这种方式会导致内存泄漏 如果在针对...

img1.Source = new BitmapImage(new Uri(@"image file path", UriKind.RelativeOrAbsolute)); 利用這樣的方式，將圖片檔案顯示在Imagez上面；如果來源是byte array的話，會利用類似這樣的方式 System.IO.FileStream fs = new System.IO.FileStream(filepath, System.IO.FileMode.Open, System.IO.File...
