here basically is the code:
Byte[w*h] barray = new byte[w*h];
Mashal.copy((intptr)(img), barray, 0,w*h);
GChandle hd = GChandle.Alloc(barray, Gchandletype.Pinned);
try
{IntPtr p = hd.AddrofPinnedObject();
Bitmap b = Bitmap.FromHbitmap(p);}
finally
{;}
the line bitmap.fromhbitmap(p), will throw an error

发帖数: 2604 | 2 Yes, I did with following code
Byte[w*h] barray = new byte[w*h]; Mashal.copy((intptr)(img), barray, 0,w*h);
unsafe{fixed(byte* parray=barray)
{InrPtr p= new IntPtr((void* parray));
Bitmap bmp = Bitmap.FromHbitmap(p);}}
same error, on lastline give me "A generic error occured in GDI+"
Is there anything wrong with the code?
do u think the size w,h matters, cz in the run time they are 1066,782 which
is weird to me.
thank u.

很糟糕，大数据过不去
应该可以用bitmap 优化一下 今天懒得弄了

发帖数: 2604 | 4 how should I get the "array" in the example code. what is the way to read it
from memory? Something like this?
short* img;
int w;
int h;
Byte[] barray = new Byte[w*h*3];
Marshal.copy(IntPtr(img), barray, 0, w*h*3);
