WPF BitmapImage内存使用率
|
我正在尝试将图像的字节数组转换为BitmapImage以绑定到按钮。
public static BitmapImage GetBitmapImageFromByteArray(byte[] p_Image)
{
try
{
BitmapImage bmpImage;
if (p_Image != null)
{
using (MemoryStream msStream = new MemoryStream(p_Image))
{
msStream.Position = 0;
bmpImage = GetBitmapImageFromStream(msStream);
//msStream.Close();
return bmpImage;
}
}
}
catch
{
}
return null;
}
public static BitmapImage GetBitmapImageFromStream(MemoryStream msImage)
{
try
{
if (msImage == null) return null;
BitmapImage bmpImg = new BitmapImage();
msImage.Position = 0;
bmpImg.BeginInit();
bmpImg.CacheOption = BitmapCacheOption.OnLoad;
bmpImg.StreamSource = msImage;
bmpImg.EndInit();
return bmpImg;
}
catch
{
return null;
}
}
没有找到相关结果

不会收集所有复制到流中的数据，但内存中将有多个副本。联课
var bmpImg = new BitmapImage(); msImage.Position = 0; bmpImg.BeginInit(); bmpImg.DecodePixelHeight =containerHeight; bmpImg.CacheOption = BitmapCacheOption.OnLoad; bmpImg.StreamSource = msImage; bmpImg.EndInit(); return bmpImg;
