C＃System.OutOfMemoryException：'内存不足'。 [英] C# System.OutOfMemoryException: 'Out of memory.'
问题描述
我正在使用AForge的videoSourcePlayer。现在我不得不为它添加一个函数，因为GetCurrentVideoFrame（）不能正常工作我需要的原因。所以我创建一个名为GetCurrent（）的
函数，它按照我想要的方式工作。我遇到的问题是当我使用它代替GetCurrentVideoFrame（）时，我得到一个System.OutOfMemoryException：'内存不足。'例外，我没有理想的原因。这是我的代码：
Bitmap getPic2（int i2）
{
位图bmp = null;
位图tempB = null;
if（endIRList [i2] .X> videoSourcePlayer.Width - 1）
endIRList [i2] = new System.Drawing.Point（videoSourcePlayer.Width - 1，endIRList [i2] .Y）;
if（endIRList [i2] .Y> videoSourcePlayer.Height - 1）
endIRList [i2] = new System.Drawing.Point（endIRList [i2] .X，videoSourcePlayer.Height - 1）;
if（stIRList [i2] .X> = 0&& stIRList [i2] .Y> = 0&& endIRList [i2] .X< videoSourcePlayer.Width&& endIRList [i2] .Y< videoSourcePlayer.Height）
{
if（endIRList [i2] .X - stIRList [i2] .X> 0&& endIRList [i2] .Y - stIRList [i2] .Y> 0）
{
bmp = videoSourcePlayer.GetCurrent（）;
System.Drawing.Image iOld = p2.Image;
tempB = bmp.Clone（new Rectangle（stIRList [i2] .X，stIRList [i2] .Y，endIRList [i2] .X - stIRList [i2] .X，endIRList [i2] .Y - stIRList [ 12] .Y），bmp.PixelFormat）;
if（iOld！= null）
{
iOld.Dispose（）;
iOld = null;
}
}
}
pictureBox1.Image = this.videoSourcePlayer.GetCurrent（）;
TestPicBox.Image = tempB;
返回tempB;
}
我遇到的问题是：
tempB = bmp 。 克隆 （ new Rectangle （ stIRList [ i2 ]。 X ， stIRList [ i2 ]。 Y ， endIRList [ i2 ]。 X - stIRList [ i2 ]。 X ， endIRList [ i2 ]。 Y - stIRList [ i2 ]。 Y ）， bmp 。 PixelFormat ）;

{
iOld.Dispose（）;
iOld = null;
}
}
}
pictureBox1.Image = this.videoSourcePlayer.GetCurrent（）;
TestPicBox.Image = tempB;
返回tempB;
}我遇到的问题是：
tempB = bmp 。 Clone （ new < span class ="typ"style ="margin：0px; padding：0px; border：0px; vertical-align：baseline; color：＃2b91af; font-style：inherit; font-variant：inherit; font-weight：inherit; line-height：inherit; font-family：inherit"> Rectangle （ stIRList [ i2 ]。 X ， stIRList [ i2 ]。 Y ， endIRList [ i2 ]。 X - stIRList [ i2 ]。 X ， endIRList [ i2 ]。 Y - stIRList [ i2 ]。 Y ）， bmp 。 PixelFormat ）;
现在如果我只是使用bmp = GetCurrentVideoFrame我没有遇到问题。所以我的函数GetCurrentVideo出现问题
这里是代码：public Bitmap GetCurrentVideoFrame（）
{
lock（sync）
{
return（currentFrame == null）？null：AForge.Imaging.Image.Clone（currentFrame）;
}
}
public Bitmap GetCurrent （）
{
lock（sync）
{
Bitmap original = GetCurrentVideoFrame（）;
currentPic = new Bitmap（original，new Size（original） .Width / 2，original.Height / 2））;
original.Dispose（）;
original = null;
return currentPic;
}
}
我只是看不出为什么他们的功能有效而且我没有。有人可以帮忙吗？
I am using videoSourcePlayer from AForge. now I had to add a function to it because GetCurrentVideoFrame( ) was not working the why I needed. So I make a function called GetCurrent() and it work the way I wanted. The problem I am having is when I used it in place of GetCurrentVideoFrame( ) I get a System.OutOfMemoryException: 'Out of memory.' Exception and I have no Ideal why. here is my code :
Bitmap getPic2(int i2)
{
Bitmap bmp = null;
Bitmap tempB = null;
if (endIRList[i2].X > videoSourcePlayer.Width - 1)
endIRList[i2]= new System.Drawing.Point(videoSourcePlayer.Width - 1, endIRList[i2].Y);
if (endIRList[i2].Y > videoSourcePlayer.Height - 1)
endIRList[i2] = new System.Drawing.Point(endIRList[i2].X, videoSourcePlayer.Height - 1);
if (stIRList[i2].X >= 0 && stIRList[i2].Y >= 0 && endIRList[i2].X < videoSourcePlayer.Width && endIRList[i2].Y < videoSourcePlayer.Height)
{
if (endIRList[i2].X - stIRList[i2].X > 0 && endIRList[i2].Y - stIRList[i2].Y > 0)
{
bmp = videoSourcePlayer.GetCurrent();
System.Drawing.Image iOld = p2.Image;
tempB = bmp.Clone(new Rectangle(stIRList[i2].X, stIRList[i2].Y, endIRList[i2].X - stIRList[i2].X, endIRList[i2].Y - stIRList[i2].Y),bmp.PixelFormat);
if (iOld != null)
{
iOld.Dispose();
iOld = null;
}
}
}
pictureBox1.Image =this.videoSourcePlayer.GetCurrent();
TestPicBox.Image = tempB;
return tempB;
}the problem I am having is at:
tempB = bmp.Clone(new Rectangle(stIRList[i2].X, stIRList[i2].Y, endIRList[i2].X - stIRList[i2].X, endIRList[i2].Y - stIRList[i2].Y),bmp.PixelFormat);I am using videoSourcePlayer from AForge. now I had to add a function to it because GetCurrentVideoFrame( ) was not working the why I needed. So I make a function called GetCurrent() and it work the way I wanted. The problem I am having is when I used it in place of GetCurrentVideoFrame( ) I get a System.OutOfMemoryException: 'Out of memory.' Exception and I have no Ideal why. here is my code :
Bitmap getPic2(int i2) { Bitmap bmp = null; Bitmap tempB = null; if (endIRList[i2].X > videoSourcePlayer.Width - 1) endIRList[i2]= new System.Drawing.Point(videoSourcePlayer.Width - 1, endIRList[i2].Y); if (endIRList[i2].Y > videoSourcePlayer.Height - 1) endIRList[i2] = new System.Drawing.Point(endIRList[i2].X, videoSourcePlayer.Height - 1); if (stIRList[i2].X >= 0 && stIRList[i2].Y >= 0 && endIRList[i2].X < videoSourcePlayer.Width && endIRList[i2].Y < videoSourcePlayer.Height) { if (endIRList[i2].X - stIRList[i2].X > 0 && endIRList[i2].Y - stIRList[i2].Y > 0) { bmp = videoSourcePlayer.GetCurrent(); System.Drawing.Image iOld = p2.Image; tempB = bmp.Clone(new Rectangle(stIRList[i2].X, stIRList[i2].Y, endIRList[i2].X - stIRList[i2].X, endIRList[i2].Y - stIRList[i2].Y),bmp.PixelFormat); if (iOld != null) { iOld.Dispose(); iOld = null; } } } pictureBox1.Image =this.videoSourcePlayer.GetCurrent(); TestPicBox.Image = tempB; return tempB; }the problem I am having is at:
tempB = bmp.Clone(new Rectangle(stIRList[i2].X, stIRList[i2].Y, endIRList[i2].X - stIRList[i2].X, endIRList[i2].Y - stIRList[i2].Y),bmp.PixelFormat);
now if I just use bmp = GetCurrentVideoFrame I do not get the problem. so something most be wrong with my function GetCurrentVideo
here is the code :
public Bitmap GetCurrentVideoFrame( ) { lock ( sync ) { return ( currentFrame == null ) ? null : AForge.Imaging.Image.Clone( currentFrame ); } } public Bitmap GetCurrent() { lock (sync) { Bitmap original = GetCurrentVideoFrame(); currentPic = new Bitmap(original, new Size(original.Width / 2, original.Height / 2)); original.Dispose(); original = null; return currentPic; } }
I just cant see why their function works and my does not. can anyone help?
